To aid urban planners and residents in understanding the nuances of day-to-day urban dynamics, we actively pursue the improvement of data visualisation tools that can adapt to changing conditions. An architecture was created and implemented that ensures secure and easy connectivity between various sources, such as a network of Internet of Things (IoT) devices, to merge with crowdsensing data and use them efficiently. In addition, we expanded the scope of our study to include the development of mobile and online applications, emphasizing the integration of autonomous and geo-surveillance. The main findings highlight the importance of sensor data in urban knowledge. Their incorporation via Tepresentational State Transfer (REST) Application Programming Interface (APIs) improves data access and informed decision-making, and dynamic data visualisation provides better insights.

Given the relevance of these topics, the present study focused on the analysis of customer complaint data, employing ML techniques to anticipate complaint accountability. The primary objective was to enhance data accessibility, harnessing the potential of ML models to optimize the complaint handling process and thereby positively contribute to data-driven decision-making. This approach aimed not only to reduce the number of units to be analyzed and customer response time but also to underscore the pressing need for a paradigm shift in quality management. The application of AI techniques sought to enhance not only the efficiency of the complaint handling process and data accessibility but also to demonstrate how the integration of these innovative approaches could profoundly transform the way quality is conceived and managed within organizations. Design/methodology/approach: To conduct this study, real customer complaint data from an automotive company was utilized. Our main objective was to highlight the importance of artificial intelligence (AI) techniques in the context of quality. To achieve this, we adopted a methodology consisting of 10 distinct phases: business analysis and understanding; project plan definition; sample definition; data exploration; data processing and pre-processing; feature selection; acquisition of predictive models; evaluation of the models; presentation of the results; and implementation. This methodology was adapted from data mining methodologies referenced in the literature, taking into account the specific reality of the company under study. This ensured that the obtained results were applicable and replicable across different fields, thereby strengthening the relevance and generalizability of our research findings. Findings: The achieved results not only demonstrated the ability of ML models to predict complaint accountability with an accuracy of 64%, but also underscored the significance of the adopted approach within the context of Quality 4.0 (Q4.0). This study served as a proof of concept in complaint analysis, enabling process automation and the development of a guide applicable across various areas of the company. The successful integration of AI techniques and Q4.0 principles highlighted the pressing need to apply concepts of digitization and artificial intelligence in quality management. Furthermore, it emphasized the critical importance of data, its organization, analysis and availability in driving digital transformation and enhancing operational efficiency across all company domains. In summary, this work not only showcased the advancements achieved through ML application but also emphasized the pivotal role of data and digitization in the ongoing evolution of Quality 4.0. Originality/value: This study presents a significant contribution by exploring complaint data within the organization, an area lacking investigation in real-world contexts, particularly focusing on practical applications. The development of standardized processes for data handling and the application of predictions for classification models not only demonstrated the viability of this approach but also provided a valuable proof of concept for the company. Most importantly, this work was designed to be replicable in other areas of the factory, serving as a fundamental basis for the company’s data scientists. Until then, limited data access and lack of automation in its treatment and analysis represented significant challenges. In the context of Quality 4.0, this study highlights not only the immediate advantages for decision-making and predicting complaint outcomes but also the long-term benefits, including clearer and standardized processes, data-driven decision-making and improved analysis time. Thus, this study not only underscores the importance of data and the application of AI techniques in the era of quality but also fills a knowledge gap by providing an innovative and replicable approach to complaint analysis within the organization. In terms of originality, this article stands out for addressing an underexplored area and providing a tangible and applicable solution for the company, highlighting the intrinsic value of aligning quality with AI and digitization. © 2024, Anabela Costa Silva, José Machado and Paulo Sampaio.}, note = {cited By 0}, keywords = {Artificial intelligence techniques; Customer complaints; Data accessibility; Decisions makings; Digital transformation; Digitisation; Machine learning and customer complaint; Machine-learning; Predictive models; Quality 4.0, Data mining; Forecasting; Industry 4.0; Learning systems; Machine learning; Metadata; Quality control; Quality management; Sales, Decision making}, pubstate = {published}, tppubtype = {article} } @inproceedings{Sousa2024467, title = {The Interplay of Inflation, Healthcare Spending, and Suicide Rates: An Empirical Analysis}, author = {R.

The demand for online job searching and searching for labor regulations in legal documents, particularly regarding the policy for unemployment benefits, is essential. Nowadays, each function has some programs for its working. However, there is no program that combines both functions. In practice, when users seek a job, they may be unemployed or want to transfer to another work. Thus, they are required to search for regulations about unemployment insurance policies and related information, as well as regulations about workers working smoothly and following labor law. Ontology is a useful technique for representing areas of practical knowledge. This article proposes an ontology-based method for solving labor and employment-related problems. First, we construct an ontology of job skills to match curriculum vitae (CV) and job descriptions (JD). In addition, an ontology for representing labor law documents is proposed to aid users in their search for legal labor law regulations. These ontologies are combined to construct the knowledge base of a job-searching and labor law-searching system. In addition, this integrated ontology is used to study several issues involving the matching of CVs and JDs and the search for labor law issues. A system for intelligent resume searching in information technology is developed using the proposed method. This system also incorporates queries pertaining to Vietnamese labor law policies regarding unemployment and healthcare benefits. The experimental results demonstrate that the method designed to assist job seekers and users searching for legal labor documents is effective. © 2024 Nguyen et al.}, note = {cited By 0}, keywords = {Employment; Insurance; Knowledge representation; Laws and legislation; Personnel; Search engines, Intelligent search systems; Job description; Knowledge-based systems; Knowledge-representation; Labor laws; Legal documents; Ontology's; Searching systems; Talent acquisition; Unemployment insurance, Ontology}, pubstate = {published}, tppubtype = {article} } @inproceedings{Sousa2024452, title = {Towards a Standardized Real-Time Data Repository based on Laboratory Test Results}, author = {R.

However, testing the new methodologies or technologies directly in the real world is an almost impossible feat that, inclusively, can result in disaster. Thus, there is the importance of simulation. Simulation enables testing new and complex methodologies and gauging their impact in a realistic context without adding any safety issues. Additionally, these can accurately map real-world conditions depending on the simulation configuration. One key aspect of the simulation is the traffic flows in the simulated region. These may be hard to find and, if ill-set, may introduce bias in the results. This work is on the characterization of the traffic in the city center of Guimarães, Portugal.

In conducting the sentiment analysis, the FinBERT model was used to classify dividend news headlines into positive, negative, and neutral sentiment. Then, a Spearman rank correlation test is conducted with the closing price of the stock to see the relationship. The results show that the sentiment formed by news headlines is dominated by neutral sentiment (46%), followed by positive sentiment (28%) and negative sentiment (26%). The study, conducted over the 2018-2022 dividend period, shows a positive relationship between news headlines and stock returns. The analysis shows that the sentiment conveyed in news headlines has a statistically significant positive correlation with changes in company stock returns. These findings suggest that the sentiment expressed in news headlines can serve as a valuable indicator for predicting and understanding fluctuations in stock returns during dividend periods. © 2023 IEEE.}, note = {cited By 0; Conference of 2023 International Conference on Digital Business and Technology Management, ICONDBTM 2023 ; Conference Date: 2 August 2023 Through 3 August 2023; Conference Code:195011}, keywords = {Asymmetric information; Company performance; Dividend period; FinBERT; Headline news; Informed decision; Investment decisions; Sentiment analysis; Stock price fluctuation; Stock returns, Costs; Financial markets; Investments, Sentiment analysis}, pubstate = {published}, tppubtype = {inproceedings} } @article{Machado2023C1, title = {Correction to: Distributed Computing and Artificial Intelligence, Special Sessions, 19th International Conference (Springer Science and Business Media Deutschland GmbH, 10.1007/978-3-031-23210-7)}, author = {J.

The incidence of ABI has increased in recent years, highlighting the need for a comprehensive approach to treatment and rehabilitation to improve patients’ quality of life.

This problem exacerbates the complexity of designing the rehabilitation activities, which is a time-consuming and complicated task that may cause poor patient recovery, if such activities are poorly designed. In order to overcome this problem, it is common practice to create groups of patients with similar complaints and deficits and to design rehabilitation activities that may be reused internally by such groups, facilitating comparative analyses. Usually, such grouping is conducted by specialists who may neglect to detect commonalities due to the huge amount of information to be processed.

In recent years, there has been a significant increase in the incidence of ABI, highlighting the need for a comprehensive approach that improves the rehabilitation process and, thus, provides people with ABI with a better quality of life. Developing appropriate rehabilitation activities for these patients is a major challenge for experts in the field, as their poor design can hinder the recovery process. One way to address this problem is through the use of smart systems that generate such rehabilitation activities in an automatic way that can then be modified by therapists as they deem appropriate. This automatic generation of rehabilitation activities uses experts’ knowledge to determine their suitability according to the patient’s needs. The problem is that this knowledge may be ill-defined, hampering the rehabilitation process. This paper investigates the possibility of applying Deep Q-Networks, a Reinforcement Learning (RL) algorithm, to evolve and adapt that information according to the outcomes of the rehabilitation process of groups of patients. This will help minimize possible errors made by experts and improve the rehabilitation process. © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.}, note = {cited By 0; Conference of 15th International Conference on Ubiquitous Computing and Ambient Intelligence, UCAmI 2023 ; Conference Date: 28 November 2023 Through 29 November 2023; Conference Code:304769}, keywords = {Acquired brain injuries; Condition; Deep q-network; Gesture interaction; Multi-modal; Multimodal gesture interaction; Rehabilitation activities; Reinforcement learning algorithms; Reinforcement learnings; Telerehabilitation, Brain; Deep learning; Learning algorithms; Patient rehabilitation, Reinforcement learning}, pubstate = {published}, tppubtype = {inproceedings} } @inproceedings{Hernández2023300, title = {A Machine Learning Approach to Evaluating the Relationship Between Dental Extraction and Craniofacial Growth in Adolescents}, author = {G.

The lack of interoperability in Health Information Systems (HIS) has been a significant challenge. The need for systems that promote interoperability between HIS within the same institution or even between HIS from different institutions is a worldwide concern. A system that contributes to improving interoperability in healthcare through the use of the openEHR standard is proposed with this paper. The system provides a way to manipulate clinical data by creating an artifact built with React and NextJS that allows the conversion of openEHR standardized data into a JSON object. The artifact being a web application presents a new way for users to check openEHR data, while the API can be used by developers to work with openEHR data in a more accessible and supported way.

Although the DenseNet model achieves the highest score with 93.7% Area Under the ROC Curve (AUC) and 97.4% Average Precision Score (APS), the BiT model is more suitable for deployment in a real-world setting since it can predict more malignant cases correctly than the other two models with a sensitivity score of 90.79%. © 2023 IEEE.}, note = {cited By 0; Conference of 5th International Conference on Advancement in Data Science, E-Learning and Information Systems, ICADEIS 2023 ; Conference Date: 2 August 2023 Through 3 August 2023; Conference Code:193233}, keywords = {Breast Cancer; Breast cancer detection; Cancer detection; Deep learning; Learning models; Learning techniques; Specific tasks; Transfer learning; Vision model; World Health Organization, Computer vision, Deep learning; Diseases; Learning systems; Medical imaging; Transfer learning}, pubstate = {published}, tppubtype = {inproceedings} } @inproceedings{Arfilinia2023, title = {Multidimensional Sentiment Analysis of Tourism Object in DKI Jakarta, Banten, East Java, Central Java and West Java using Support Vector Machine Algorithm}, author = {A.

This study aims to utilize process mining techniques to analyze event logs and identify bottleneck activities within the billing process. By evaluating the process, the research aims to understand the causality behind these bottlenecks and propose effective solutions for enhancing efficiency and reducing time costs. The research employs the PM4Py open-source toolkit, including PM4Py-GPU for computationally intensive tasks. Through fitness alignments between event logs and process models, it is found that approximately 47.128 percent of traces match the process model, exhibiting a good level of conformity with an average fitness of 0.8888. Notably, the study reveals that over 3 percent of billing processes in regional hospitals exhibit repetitive occurrences of specific activities consecutively. The identification of this repetitive activity pattern prompts a deeper investigation into its root causes and implications for resource utilization and performance. By addressing these causative factors, the research aims to propose optimized approaches to streamline the billing process, thus enhancing overall efficiency and customer satisfaction levels for the hospitals.

Furthermore, there is a need to reduce the gap on time from when information is created to when actions and insights can be offered. However, a challenge in implementing a large-scale data processing architecture is deciding which tools are appropriate, and how to apply them in the best way possible. For example, streaming systems are now mature enough that hospitals worldwide can use their extremely large datasets, along with data producers, to predict and influence future events. Thus, the main objective of this systematic review is to identify the state-of-the-art in data platforms on healthcare that allow the creation of metrics and actions in real-time. The PRISMA guideline for reporting systematic reviews was implemented to deliver a transparent and consistent report, validating the technological advances in a critical sector. Multiple pertinent articles and papers were retrieved from the SCOPUS abstract and citation database on May 13, 2022, using several relevant keywords to identify potentially relevant documents published from January 2020 onward. These documents must have already been published in English and been already published, and accessible through the B-ON consortium that allows Portuguese students to legally download from most publishers. Over seven studies have been selected for deeper discussion based on their relevance and impact for this review, showcasing their main objectives, data sources, and tools used, as well as their approaches for interoperability and support of machine learning algorithms for decision support. In closing, the collected articles have shown that while Big Data is currently in use at health institutions of all sizes, the ability of processing large amounts of data from sensors and events, and notifying stakeholders as quickly as possible is still in its infancy. © 2023 Elsevier B.V..

Continuous improvement has made the care provided a factor of excellence in the population, improving people’s daily lives and increasing average life expectancy. Even so, the resulting aging has caused patterns to increase day by day and the paradigm of medicine to shift from reaction to prevention. Often, the principle of evidence-based medicine is compromised by lack of evidence on pathogenic mechanisms, risk prediction, lack of resources, and effective therapeutic strategies. This is even more evident in pandemic situations. The current data management tools (centered in a single machine) do not have an ideal behavior for the processing of large amounts of information. This fact combined with the lack of sensitivity for the health area makes it imminent the need to create and implement an architecture that performs this management and processing effectively. In this sense, this paper aims to study the problem of knowledge construction from Big Data in health institutions.

Recent research shows a growing interest in using Text Mining via NLP to extract drug–drug interactions from unstructured data sources to support clinical prescribing decisions. NLP text mining and machine learning classifier training for drug relation extraction were used in this process. In this context, the proposed solution allows to develop an extraction system for drug–drug interactions from unstructured data sources. The system produces structured information, which can be inserted into a database that contains information acquired from three different data sources. The architecture outlined for the drug–drug interaction extraction system is capable of receiving unstructured text, identifying drug entities sentence by sentence, and determining whether or not there are interactions between them. © 2023 The Authors.

Data was explored in this study in order to determine which attributes, techniques, and approaches can effectively improve this predictive objective. The main approaches to investigating the data using CRISP-DM were classification and association rules, a methodology that allows searching and finding hidden patterns and relations within data. Results obtained and represented show sensitivity and accuracy values higher than 70%, using J48 and SVM classification algorithms, and allowed to examine that social-economical attributes are not enough to illness prediction. The same applies when only those most indicative characteristics are used—i.e. physical activity, healthy eating and lifestyle, regular health exams—which indicates that a greater set of information is needed so as to be designed an effective model.

An analysis of the model’s convergence was conducted, followed by adversarial robustness for each model and a sanity-check based on interpretability analysis.

Many problems occurred due to difficulties in dividing the vaccination recipient areas. This is due to the large number of regions with different conditions for each region. One of the efforts to assist the process of processing large vaccination data is data mining techniques and using the clustering method with the K-medoids algorithm. In this study, data on COVID-19 vaccination was grouped in the East Jakarta area using the K-medoids algorithm clustering method. The calculation is carried out using the Euclidean Distance equation and the value of S > 0. The grouped area categories are at the kelurahan level which will then be divided into several clusters. The clustering process was carried out with RapidMiner on 267 kelurahan data on four main attributes, namely the number of targets, the number of vaccine doses 1, the number of vaccine doses 2, and the number of vaccine doses 3. The clustering process was carried out in 6 simulations with variations of k medoids as much as 2 to 7. The results of clustering show the best number of clusters obtained in the simulation is cluster 6 with the smallest Davies Bouldin Index (DBI) value of 0.209. The clusters obtained are clusters 0 to cluster 5.

To achieve the goals, a simulation-based optimization strategy using the Particle Swarm Optimization combined with the Simulation of Urban Mobility software was used to minimize the average waiting time of the vehicles by determining the optimal value of the traffic light cycle. The computational results showed it is possible to decrease by 78.2% the average value of the waiting time.

On one hand, clinicians can be mislead into which test is the best option for each clinical case, on the other hand missing previous results, leads to duplication or unnecessary tests. HIS is increasingly relying on standards based on dual architecture to promote interoperability as well as the structuring and consistency of clinical and demographic data. The OpenEHR standard's duo-based architecture allows for concise modelling of archetypes and templates for a given clinical case, which was used in this study. As a result, the purpose of this research was to build an openEHR template for the CDR registration as well as the architecture of a Data Warehouse (DW) system capable of storing all of the information needed for the diagnostic test request process.

Sustainability is essential for urban transformation to achieve more resource-efficient, resilient and smart cities. The main objective of sustainable cities is to guide decisions for interventions in the city. Monitoring systems are examples of measures that aspire to ensure greater sustainability and energy efficiency, such as the application of air quality meters or smart water and light meters. Throughout the analysis of the collected data, it’s possible to develop alert systems and optimization models considering various metrics based on artificial intelligence. Therefore, allowing users to make better decisions to positively affect the course of actions in their cities and make it possible to apply sustainability and social energy measures. Thus, it is possible to reduce and improve the consumption of natural resources. Industry 5.0 is crucial in the evolution of smart cities.

Hybrid FPGA-CPU boards emerged as an alternative to server GPUs in the role of edge devices in autonomous vehicles. Despite their energy efficiency, such devices do not offer the same computational power as GPU servers and have fewer resources available. This paper investigates how to deploy deep learning models tailored to object detection in point clouds in edge devices for onboard real-time inference. Different approaches, requiring different levels of expertise in logic programming applied to FPGAs, are explored, resulting in three main solutions: utilization of software tools for model adaptation and compilation for a proprietary hardware IP; design and implementation of a hardware IP optimized for computing traditional convolutions operations; design and implementation of a hardware IP optimized for sparse convolutions operations. The performance of these solutions is compared in the KITTI dataset with computer performances. All the solutions resort to parallelism, quantization and optimized access control to memory to reduce the usage of logical FPGA resources, and improve processing time without significantly sacrificing accuracy.

Traffic light timed regulated intersections are one of the solutions used to improve traffic flow without the need for large-scale and costly infrastructure changes. A specific situation where traffic lights are used is on single-lane roads, often found on roads under maintenance, narrow roads or bridges where it is impossible to have two lanes. In this paper, a simulation-optimization strategy is tested for this scenario. A Particle Swarm Optimization algorithm is used to find the optimal solution to the traffic light timing problem in order to reduce the waiting times for crossing the lane in a simulated vehicle system. To assess vehicle waiting times, a network is implemented using the Simulation of Urban MObility software. The performance of the PSO is analyzed by testing different parameters of the algorithm in solving the optimization problem. The results of the traffic light time optimization show that the proposed methodology is able to obtain a decrease of almost 26% in the average waiting times. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.}, note = {cited By 2; Conference of 22nd International Conference on Computational Science and Its Applications , ICCSA 2022 ; Conference Date: 4 July 2022 Through 7 July 2022; Conference Code:281299}, keywords = {Bridges; Computer software; Particle swarm optimization (PSO); Street traffic control; Traffic signals, Large cities; Particle swarm; Particle swarm optimization; Simulation of urban mobility; Swarm optimization; Traffic flow; Traffic light; Traffic light problem; Urban mobility; Waiting time, Traffic congestion}, pubstate = {published}, tppubtype = {inproceedings} } @inproceedings{Witeck202243, title = {A Bibliometric Review and Analysis of Traffic Lights Optimization}, author = {G.

The use of simulation for real intersections can be effective in optimizing the cycle times and improving the traffic light timing to coordinate vehicles passing through intersections. From these themes emerge the research questions: How are the existing approaches (optimization techniques and simulation) to managing traffic lights smartly? What kind of data (offline and online) are used for traffic lights optimization? How beneficial is it to propose an optimization approach to the traffic system? This paper aims to answer these questions, carried out through a bibliometric literature review. In total, 93 articles were analyzed. The main findings revealed that the United States and China are the countries with the most studies published in the last ten years. Moreover, Particle Swarm Optimization is a frequently used approach, and there is a tendency for studies to perform optimization of real cases by real-time data, showing that the praxis of smart cities has resorted to smart traffic lights. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.}, note = {cited By 0; Conference of 22nd International Conference on Computational Science and Its Applications , ICCSA 2022 ; Conference Date: 4 July 2022 Through 7 July 2022; Conference Code:281299}, keywords = {Bibliometric; Cycle time; Number of vehicles; Optimisations; Research questions; Traffic light; Travel-time; Urban areas; Urban mobility; Urban travels, Particle swarm optimization (PSO); Travel time, Smart city}, pubstate = {published}, tppubtype = {inproceedings} } @inproceedings{Burduk2022, title = {Efficiency forecasting of electric bundle assembly with use of ANN model}, author = {A.

In this case, it can be helpful to use models of artificial neural networks (ANN) that, on the grounds of accessible data, will determine results of the made decision. One of the key problems in production companies is determination of execution time and cost of a production order. The problem is especially important in a company manufacturing a variable product line with a big part of manual operations. In the article, the way of building an ANN model for efficiency forecasting of the assembly process of electric bundles is presented. With regard to the very wide and variable product line, the products with different complexity degree are manufactured on three types of assembly lines. The assembly processes are performed on the assembly lines manually by groups of workers, so efficiency of the process is influenced mostly by skills and experience of these workers. Therefore, numbers of new assembly workers assigned to individual assembly lines and quantities of new products in the production schedule are selected as explanatory variables in the ANN model. The explained variable in the ANN model is production volume of the manufactured electric bundles. © Published under licence by IOP Publishing Ltd.}, note = {cited By 0; Conference of 15th Global Congress on Manufacturing and Management, GCMM 2021 ; Conference Date: 25 November 2020 Through 27 November 2020; Conference Code:180965}, keywords = {Artificial neural network modeling; Assembly line; Assembly process; Decision-based; IT system; Production companies; Production system; Productline; Use-model; Workers', Assembly, Assembly machines; Information management; Manufacture; Neural networks; Production control; Production efficiency}, pubstate = {published}, tppubtype = {inproceedings} } @inproceedings{Silva2022726, title = {Rule-based Clinical Decision Support System using the OpenEHR Standard}, author = {S.

One of the solutions to accelerate the current knowledge about RCC is through the use of Data Mining techniques based on patients' personal and clinical data. Therefore, it is crucial to understand which techniques are the most suitable to extract knowledge about this disease. In this paper, we followed the CRISP-DM methodology to simulate different techniques to determine the ones with the best predictive performance. For this purpose, we used a dataset of 821 records of RCC patients, obtained from The Cancer Genome Atlas. The present work tests different Data Mining techniques, that can be used to predict the 5-year life expectancy of patients with renal cancer and to predict the number of days to death for patients who have a life expectancy of less than 5 years. The results obtained demonstrated that the best algorithm for estimating the vital status at 5 years was Random Forest. This algorithm presented an accuracy of 87.65% and an AUROC of 0.931. For the prediction of days to death, the best performance was obtained with the k-Nearest Neighbors algorithm with a root mean square error of 354.6 days. The work suggested that Data Mining techniques can help to understand the influence of various risk factors on the life expectancy of patients with RCC. © 2022, ICST Institute for Computer Sciences, Social Informatics and Telecommunications Engineering.}, note = {cited By 1; Conference of 8th EAI International Conference on IoT Technologies for Health-Care, HealthyIoT 2021 ; Conference Date: 24 November 2021 Through 26 November 2021; Conference Code:275359}, keywords = {'current; Clinical data; Comparatives studies; CRISP-DM; Data-mining techniques; Kidney cancer; Life expectancies; Rapidminer; Renal cell carcinoma; Survival, Data mining, Decision trees; Diseases; Forecasting; Mean square error; Nearest neighbor search}, pubstate = {published}, tppubtype = {inproceedings} } @inproceedings{Guisasola2022271, title = {Detecting Autism Spectrum Disorder Using Data Mining}, author = {A.

Early detection and treatment are critical factors to reduce the risk of long-term complications, such as type 2 diabetes and heart disease. With the vast amount of data being collected daily in healthcare environments, it is possible to build Decision Support Systems using Data Mining and Machine Learning. Currently, healthcare systems have advanced skills like Artificial Intelligence, Machine Learning and Data Mining to offer intelligent and expert healthcare services. The use of efficient Data Mining techniques is able to reveal and extract hidden information from clinical and laboratory patient data, which can be helpful to assist doctors in maximizing the accuracy of the diagnosis. In this sense, this paper aims to predict, using the classification techniques and the CRISP-DM methodology, the presence of Polycystic Ovary Syndrome. This paper compares the performance of multiple algorithms, namely, Support Vector Machines, Multilayer Perceptron Neural Network, Random Forest, Logistic Regression and Gaussian Naïve Bayes.

Through the application of Data Mining techniques it is possible to find hidden relations or patterns among the data and convert those into knowledge that can further be used to aid in the decision-making of hospital professionals. This study aims to use information about patients with diabetes, which is a chronic (long-term) condition that occurs when the body does not produce enough or any insulin. The main purpose is to help hospitals improve their care with diabetic patients and consequently reduce readmission costs. An hospital readmission is an episode in which a patient discharged from a hospital is admitted again within a specified period of time (usually a 30 day period). This period allows hospitals to verify that their services are being performed correctly and also to verify the costs of these re-admissions. The goal of the study is to predict if a patient who suffers from diabetes will be readmitted, after being discharged, using Machine Leaning algorithms. The final results revealed that the most efficient algorithm was Random Forest with 0.898 of accuracy. © 2021, The Author(s), under exclusive licence to Springer Science+Business Media, LLC part of Springer Nature.}, note = {cited By 11}, keywords = {acarbose; acetohexamide; chlorpropamide; glibenclamide; glimepiride; glipizide; insulin; metformin; miglitol; nateglinide; pioglitazone; repaglinide; rosiglitazone; tolazamide; tolbutamide; troglitazone, Algorithms; Data Mining; Diabetes Mellitus; Humans; Patient Discharge; Patient Readmission; Retrospective Studies; Risk Factors}, pubstate = {published}, tppubtype = {article} } @article{Martins2021, title = {Data Mining for Cardiovascular Disease Prediction}, author = {B.

Individuals at higher risk of developing CVD must be noticed at an early stage to prevent premature deaths. Advances in the field of computational intelligence, together with the vast amount of data produced daily in clinical settings, have made it possible to create recognition systems capable of identifying hidden patterns and useful information. This paper focuses on the application of Data Mining Techniques (DMTs) to clinical data collected during the medical examination in an attempt to predict whether or not an individual has a CVD. To this end, the CRossIndustry Standard Process for Data Mining (CRISP-DM) methodology was followed, in which five classifiers were applied, namely DT, Optimized DT, RI, RF, and DL. The models were mainly developed using the RapidMiner software with the assist of the WEKA tool and were analyzed based on accuracy, precision, sensitivity, and specificity. The results obtained were considered promising on the basis of the research for effective means of diagnosing CVD, with the best model being Optimized DT, which achieved the highest values for all the evaluation metrics, 73.54%, 75.82%, 68.89%, 78.16% and 0.788 for accuracy, precision, sensitivity, specificity, and AUC, respectively. © 2021, Springer Science+Business Media, LLC, part of Springer Nature.}, note = {cited By 39}, keywords = {artificial intelligence; cardiovascular disease; data mining; human, Artificial Intelligence; Cardiovascular Diseases; Data Mining; Humans}, pubstate = {published}, tppubtype = {article} } @inproceedings{Castanheira202144, title = {Overcoming challenges in healthcare interoperability regulatory compliance}, author = {A.

Collaborative filtering is widely used in this type of systems, but high dimensions and data sparsity are always a main problem. With the idea of deep learning gaining more importance, several works have emerged to improve this type of filtering. In this article, a product recommendation system is proposed where an autoencoder based on a collaborative filtering method is employed. A comparison of this model with the Singular Value Decomposition is made and presented in the results section. Our experiment shows a very low Root Mean Squared Error (RMSE) value, considering that the recommendations presented to the users are in line with their interests and are not affected by the data sparsity problem as the datasets are very sparse, 0.996. The results are quite promising achieving an RMSE value of 0.029 in the first dataset and 0.010 in the second one. © 2020 by the authors.}, note = {cited By 40}, keywords = {}, pubstate = {published}, tppubtype = {article} } @article{Pereira202034, title = {The clinical informatization in Portugal an approach to the national health service certification}, author = {S.

Now, we found ourselves amid another revolution: the data revolution. Easily unnoticeable, this new outlook is shifting in every possible way how we interact with the internet and, for the first time in history, how the internet interacts with us. This new kind of interactions is defined by connections between users and consumable goods (products, articles, movies, etc.). And through these connections, knowledge can be found. This is the definition of data mining. Buying online has become mainstream due to its convenience and variety, but the enormous offering options affect negatively the user experience. Millions of products are displayed online, and frequently the search for the craved product is long and tiring. This process can lead to a loss of interest from the customers and, consequentially, losing profits. The competition is increasing, and personalisation is considered the game-changer for platforms. This article follows the research and implementation of a recommender engine in a well-known Portuguese e-commerce platform specialised in clothing and sports apparel, aiming the increase in customer engagement, by providing a personalised experience with multiple types of recommendations across the platform. First, we address the reason why implementing recommender systems can benefit online platforms and the state of the art in that area. Then, a proposal and implementation of a customised system are presented, and its results discussed. © 2020, Springer Nature Switzerland AG.}, note = {cited By 2; Conference of 21th International Conference on Intelligent Data Engineering and Automated Learning, IDEAL 2020 ; Conference Date: 4 November 2020 Through 6 November 2020; Conference Code:251049}, keywords = {Data mining, Electronic commerce; Engines; Online systems; Recommender systems; User experience, Human evolution; Mining engines; Online platforms; Personalisation; State of the art}, pubstate = {published}, tppubtype = {inproceedings} } @inproceedings{Costa2020322, title = {Anticipating Maintenance in Telecom Installation Processes}, author = {D.

Today, all telecommunications companies rely on the massive amount of data generated daily to get to know the customer or study their behavior and thus create new effective strategies for their business. Within the most varied user experiences, the process of installing new services can be an event that raises doubts about their operation, degrade the user experience, or, in extreme cases, lead to maintenance interventions. Therefore, the use of advanced predictive models that can predict such occurrences become vital. With this, the company can anticipate the cases that will be problematic and reduce the number of negative experiences. The main objective of this work is to create a predictive model that, through all the available data history, can predict which customers will contact the customer service with problems derived from the installation process and have a following maintenance intervention. After analyzing an unbalanced dataset with approximately 560K entries from a Portuguese telecommunications company, and resorting to the CRISP-DM methodology for modeling, the best results were found with LightGBM which obtained an AUPRC of 0.11 and AUROC of 0.62. The best trade-off between precision and recall was found with a threshold model of 0.43 in order to maximize recall while still avoiding a large number of false negatives. © 2020, Springer Nature Switzerland AG.}, note = {cited By 0; Conference of 21th International Conference on Intelligent Data Engineering and Automated Learning, IDEAL 2020 ; Conference Date: 4 November 2020 Through 6 November 2020; Conference Code:251049}, keywords = {Competition; Economic and social effects; Installation; Maintenance; Predictive analytics; Sales; Telecommunication industry, Constant factors; Customer experience; Customer services; Negative experiences; Precision and recall; Predictive modeling; Predictive models; Threshold model, User experience}, pubstate = {published}, tppubtype = {inproceedings} } @inproceedings{Lori2020309, title = {Bridging the Gap of Neuroscience, Philosophy, and Evolutionary Biology to Propose an Approach to Machine Learning of Human-Like Ethics}, author = {N.

Although the production of large quantities of data becomes an expensive process and adds the problem of data protection, the use of synthetic data once they are artificially generated allows lower costs and eliminates the problem of data protection. A bibliographic study was carried out in this paper with articles from 2017 or later on the use of synthetic data. In these studies, it is noted that synthetic data is widely used with good results. As far as image capture is concerned, they show that 3D cameras have better results, but they are more expensive, so 2D cameras are more often used with later conversion to 3D images.

Considering that user’s resistance is a critical factor in system implementation failure, the understanding of user behavior remains a relevant object of investigation.

The major causes of absenteeism appear to be work accidents and sickness leaves, which lead to the attempt by companies of understanding how the workload is related to the health of their collaborators and, consequently, to absenteeism. Thus, this paper proposes the design and development of a Web Application based on Business Intelligence indicators in order to help the health and human resources professionals of a Portuguese company analyse the relation between absenteeism and the health and lifestyle of employees, with the intention of concluding whether the work executed on the company is harming workers’ health. Furthermore, it is intended to discover the principal motives for the numerous and more frequent absences in this company, so that it is possible to decrease the absenteeism rate and, hence, improve the decision-making process. This platform will also provide higher quality healthcare and the possibility to find patterns in the absence of collaborators, as well as reduce time-waste and errors. © Springer Nature Switzerland AG 2020.}, note = {cited By 1; Conference of International Conference on Information Technology and Systems, ICITS 2020 ; Conference Date: 5 February 2020 Through 7 February 2020; Conference Code:236869}, keywords = {Absenteeism; Decision making process; Design and Development; Information and Communication Technologies; Quality healthcare; Reduce time; WEB application; Work accidents, Competitive intelligence; Information analysis; Personnel; Telemedicine, Decision making}, pubstate = {published}, tppubtype = {inproceedings} } @article{Neto2019, title = {Application of data mining for the prediction of mortality and occurrence of complications for gastric cancer patients}, author = {C.

Nowadays, with the large amount of information present in hospital institutions, it is possible to use data mining algorithms to improve the healthcare delivery. Thus, this study, using the CRISP methodology, aims to predict not only the mortality associated with this disease, but also the occurrence of any complication following surgery. A set of classification models were tested and compared in order to improve the prediction accuracy. The study showed that, on one hand, the J48 algorithm using oversampling is the best technique to predict the mortality in gastric cancer patients, with an accuracy of approximately 74%.

The mining process may be time consuming for massive datasets. A widely used method related to knowledge discovery domain refers to association rule mining (ARM) approach, despite its shortcomings in mining large databases. As such, several approaches have been prescribed to unravel knowledge. Most of the proposed algorithms addressed data incremental issues, especially when a hefty amount of data are added to the database after the latest mining process. Three basic manipulation operations performed in a database include add, delete, and update. Any method devised in light of data incremental issues is bound to embed these three operations. The changing threshold is a long-standing problem within the data mining field. Since decision making refers to an active process, the threshold is indeed changeable. Accordingly, the present study proposes an algorithm that resolves the issue of rescanning a database that had been mined previously and allows retrieval of knowledge that satisfies several thresholds without the need to learn the process from scratch. The proposed approach displayed high accuracy in experimentation, as well as reduction in processing time by almost two-thirds of the original mining execution time. © 2019 by the authors.}, note = {cited By 26}, keywords = {}, pubstate = {published}, tppubtype = {article} } @article{Esteves2019, title = {A proof of concept of a mobile health application to support professionals in a portuguese nursing home}, author = {M.

Moreover, the lack of health information and communication technology (HICT) and the use of unsophisticated methods, such as paper, in nursing homes to clinically manage residents lead to more errors and are time-consuming. Thus, this article proposes a proof of concept of a mobile health (mHealth) application developed for the health professionals working in a Portuguese nursing home to support them at the point-of-care, namely to manage and have access to information and to help them schedule, perform, and digitally record their tasks. Additionally, clinical and performance business intelligence (BI) indicators to assist the decision-making process are also defined. Thereby, this solution aims to introduce technological improvements into the facility to improve healthcare delivery and, by taking advantage of the benefits provided by these improvements, lessen some of the workload experienced by health professionals, reduce time-waste and errors, and, ultimately, enhance elders’ quality of life and improve the quality of the services provided. © 2019 by the authors.

In this sense, a new medical exams visualization platform (AIDA-MCDT) was developed, specifically in the Hospital Center of Porto (CHP), with several new functionalities in order to make this process faster, intuitive and efficient, always guaranteeing the confidentiality and protection of patients’ personal data and significantly improving the usability of the system, leading to a better health care delivery. © Springer Nature Switzerland AG 2019.}, note = {cited By 1; Conference of World Conference on Information Systems and Technologies, WorldCIST 2019 ; Conference Date: 16 April 2019 Through 19 April 2019; Conference Code:224789}, keywords = {Computer resources; Electronic health record; Health information systems; Healthcare delivery; Interactive visualizations; Management systems; Medical exams; Visualization platforms, Data visualization; Diagnosis; Health care; Hospitals; Information technology; Information use; Management information systems; Medical problems; Visualization, Medical information systems}, pubstate = {published}, tppubtype = {inproceedings} } @inproceedings{Ferreira2019611, title = {Adaptive business intelligence in healthcare - A platform for optimising surgeries}, author = {J.

Surgery scheduling in hospital operating rooms is a high complex task due to huge volume of surgeries and the variety of combinations and constraints. This type of activity is critical and is often associated to constant delays and significant rescheduling. The main task of this work is to provide an ABI based platform capable of estimating the time of the surgeries and then optimising the scheduling (minimizing the waste of resources). Combining operational data with analytical tools this platform is able to present complex and competitive information to streamline surgery scheduling.

We also try to conclude, from the two scoring systems presented, which predicts better the situations described. Regarding the results, we concluded that the PULP scoring allows a better mortality prediction achieving, in this case, above 90% accuracy, however, the results may be inconclusive due to the lack of patients who died in the dataset used.

MS discharge is the medical specialty in which a patient gets discharged from the UD. This predictive analysis would improve medical and staff performance, not to mention, less time consuming to the patient and less expensive to both patient and the hospital. However, it is a challenging task due to the quality of data retrieved from UDs that's usually non-treated, with a lot of irrelevant information, sparse and, sometimes, incomplete. This predictive analysis is obtained through Data Mining techniques and machine learning algorithms in Weka environment. It was concluded that feature selection and structured modelling are important factors that affect classification accuracy. It was also concluded as that randomly decreasing or increasing dataset information by varying patient values does not assist directly in increasing accuracy for the prediction of MS discharge. The best results were achieved using the Bagging algorithm with a REPTree classifier and a ten-fold cross-validation, achieving 91.96 % of accuracy and 0.85 F1-score. © 2018 EUROSIS.

This notification system is used nowadays, but it faces a big problem: a huge amount of money spent for the telecommunication companies involved. Although each message cost a fraction of cents, it can easily reproduce its value in more than 50,000 euros per year per institution. Since technology and the use of smartphones has been evolving in such a quick way, it is estimated that in no more than 10 years, almost all the Portuguese population will use smartphones or have access to them. For those reasons, the main purpose of the present work, is to design and develop a mobile application in order to substitute the previous notification systems, through push up notifications on the app and by email, that can be saved on the smartphone calendar, translating in no costs associated with the notifications sent by the hospitals. The main motivation is, therefore, suppressing these costs for the hospital, bring the patients closer integrating other systems on the app and make the notification alert more efficient. Thereby, the mobile app will be able, not only to manage each notification and notify the patients, but also to check its medical event history and to schedule medical appointments. © 2018 EUROSIS.

With the proven effectiveness of Business Intelligence (BI) in many organisations, the urge to implement such tools in Healthcare arises, specifically in the healthcare of Misericórdia. In addition to the results, it presents a critical analysis of the implementation and the process followed for the development and usage of KPIs. In this work, some concepts associated with the use of BI in Misericórdias were addressed, and the architecture of the developed solution was designed. It is also important to emphasise that the solution presented is pervasive, available anywhere at any time. Through this work, it was possible to gather all the data into a single structure (Data Mart), to identify a set of aspects that can be improved and to have a generalised view of the state of operation of the organisation, as far as health care is concerned.

Once new information arrives, it triggers the ETL (extract, transform, load) procces enabling real-time processes like data mining. However, the system fails in recognize if a patient is absent from bed or not. This problem led to the development of the Patient Localization and Management System (PaLMS), a Radio-Frequency IDentification (RFID) serving as localization and monitoring system. This paper describes the PaLMS implementation as well as an intelligent Multi- Agent System for the integration of PaLMS into the hospital platform for interoperability named AIDA (Agency for Integration, Diffusion and Archive of Medical Information). At the end, an usability evaluation was performed in order to assess the level of usability of the existing systems at Centro Hospitalar do Porto, such as the PaLMS, the INTCare and the AIDA platform. In terms of usability, the system got very positive evalutions, despite the fact some medical staff argued that they lose too much time elaborating the records. © 2017 ComSIS Consortium.

Thus, an efficient triage is a good way to avoid some future problems and how much quicker it is, more the patient can benefit. The most common triage system is the Manchester Triage System that is a reliable system focused in the emergency department of a hospital. However, its use is more suitable for more widespread medical emergencies and not for specialized cases, like Gynecological and Obstetrics emergencies. To overcome these limitations, an alternative pre-triage system, integrated into an intelligent decision support system, was developed in order to better characterize the patient and correctly defined her as urgent or not. This system allows the increase of patient's safety, especially women who need immediate care. This paper includes the workflow that describes the decision process in real time in the emergency department, when women are submitted to triage and identify points of evolution. © 2017, IGI Global.}, note = {cited By 0}, keywords = {}, pubstate = {published}, tppubtype = {inbook} } @inproceedings{Carvalhosa2017, title = {Good practices in Local Government - A first overview of Portuguese reality}, author = {P.

Given the economic crisis in Portugal and poor healthcare system in need of profound improvements, the need to increase the efficiency of resource management and services is imperative. With the increasing use of Business Intelligence (BI) in organisations and the proven effectiveness of this, comes the desire to use BI in healthcare, specifically in the healthcare of Misericórdia. One of the purposes of this article is to present the results obtained through the development of the dissertation whose theme is "Prototyping of Business Intelligence component to support the management in the health area of a Misericórdia". So, in this work, some concepts associated with the use of BI in Misericórdias were addressed, and the Pervasive BI architecture of the developed solution was designed. It is also important to emphasise that the solution presented is pervasive, available anywhere at any time. Furthermore, a set of metrics were developed and the data presented in the form of dashboards, for later use by the users. Through this work, it was possible to gather all the data into a single structure (Data Mart), to identify a set of aspects that can be improved and to have a generalised view of the state of operation of the organisation, as far as health care is concerned.l. © 2017 by SCITEPRESS - Science and Technology Publications, Lda.

This paradigm fosters the modular design, implementing the separation of concerns concept and allowing an easier implementation of unit tests. In order to validate the framework, we present a prototype for an healthcare automotive app. The main goal of the app is to facilitate the access to health related points of interest such as hospitals, clinics and pharmacies. © Springer International Publishing AG 2017.}, note = {cited By 2; Conference of 5th World Conference on Information Systems and Technologies, WorldCIST ; Conference Date: 11 April 2017 Through 13 April 2017; Conference Code:190479}, keywords = {Architectural pattern; Context-aware mobile application; Design and implementations; Design Patterns; Geolocalization; Mobile frameworks; Separation of concerns concepts; Ubiquitous technology, Health care; Information systems; Information use; mHealth; Mobile computing; Web services, Interoperability}, pubstate = {published}, tppubtype = {inproceedings} } @inproceedings{Silva2017305, title = {An ontology for mapping cerebral death}, author = {A.

This work was performed through the data provided by the Centro Hospitalar do Porto - Hospital de Santo António. The ontology was used based on an analysis made to the data and with the use of a dictionary developed in the same analysis.

In this context, in Centro Hospitalar do Porto (CHP), the INTCare system was developed with the purpose to create new useful knowledge for deci sion support in real-time. It is an unquestionable potential area to develop effective systems for the prediction of clinical events, including Decision Support Systems (DSSs), for organ failure and death in Intensive Care. The INTCare uses multiple data sources that are collected at the bedside. However, this system fails on the recognition of the patient absence in bed. Thereby, this problem led to the devel opment of the Patient Localization and Management System (PaLMS), i.e., a RFID localization and monitoring system. Thus, this paper describes the PaLMS Intelligent Multi-Agent System for the integration of PaLMS into the hospital platform for Interoperability, Diffusion and Archive – Agency for Integration, Diffusion and Archive of Medical Information (AIDA) platform. On the other hand, a failure prevention system that actuates in the PaLMS agents, improving their availability, is also presented and thoroughly discussed. © Springer International Publishing AG 2017.}, note = {cited By 7; Conference of 5th World Conference on Information Systems and Technologies, WorldCIST ; Conference Date: 11 April 2017 Through 13 April 2017; Conference Code:190479}, keywords = {Clinical information; Decision support system (DSSs); Health care information system; Intelligent multi agent systems; Monitoring system; Multiple data sources; Prevention systems; Progressive expansion, Monitoring}, pubstate = {published}, tppubtype = {inproceedings} } @inproceedings{Carvalhosa2017391, title = {Pervasiveness in digital marketing – A global overview}, author = {P.

Thus, in this article, we intend to analyze some open-source/free BI tools on the market and their applicability in the clinical sphere, taking into consideration the general characteristics of the clinical environment. For this purpose, six BI tools were selected, analyzed, and tested in a practical environment. Then, a comparison metric and a ranking were defined for the tested applications in order to choose the one that best applies to the extraction of useful knowledge and clinical data in a healthcare environment. Finally, a pervasive BI platform was developed using a real case in order to prove the tool viability. © 2016 by the authors.}, note = {cited By 31}, keywords = {Benchmarking; Competitive intelligence; Decision making; Extraction; Information analysis, Clinical data; Clinical environments; Decision making process; Healthcare environments; Healthcare industry; Open sources; Real case, Health care}, pubstate = {published}, tppubtype = {article} } @inproceedings{Coelho2016762, title = {Towards of a Business Intelligence Platform to Portuguese Misericórdias}, author = {D.

The study focused on such targets as the average temperature of the coolant in the first circuit and the output power of the power generator. This study demonstrates the good results of the correlation coefficients and the root relative squared error metrics in case of the improved compromise-combined control program in comparison with the control program with the constant average temperature of the coolant in the reactor core. In terms of the results the root relative squared error metric is less than 2.8% and the correlation coefficients had values higher than 99,95%. The use of these models can contribute to improving the understanding of the internal processes because using the best regression data mining models allows to see advantages of the improved compromise-combined control program. © 2016 The Authors.}, note = {cited By 5; Conference of Conference on ENTERprise Information Systems / International Conference on Project MANagement / Conference on Health and Social Care Information Systems and Technologies, CENTERIS / ProjMAN / HCist 2016 ; Conference Date: 5 October 2016 Through 7 October 2016; Conference Code:121650}, keywords = {Combined control; Control program; Correlation coefficient; Data mining models; Nuclear power unit; Regression model; Simulink software; VVER-1000, Coolants; Data mining; Information systems; Nuclear energy; Nuclear fuels; Nuclear power plants; Project management; Regression analysis, Information management}, pubstate = {published}, tppubtype = {inproceedings} } @inproceedings{Peixoto2016528, title = {Resurgery Clusters in Intensive Medicine}, author = {R.

The way in which this information is presented, and especially when it is presented, may make it difficult for the intensivists within intense healthcare units to understand a patient's state in a timely fashion. Should there be a need to cross various types of clinical data from various sources, the situation worsens considerably. To support the health professional's decision-making process, the Pervasive Business Intelligence (PBI) Systems are a forthcoming field. Based on this principle, the current study approaches the way to present information about the patients, after they are received in a BI system, making them available at any place and at any time for the intensivists that may need it for the decision-making. The patient's history will, therefore, be available, allowing examination of the vital signs data, what medicine that they might need, health checks performed, among others. Then, it is of vital importance, to make these conclusions available to the health professionals every time they might need, so as to aid them in the decision-making. This study aims to make a stance by approaching the theme of PBI in Critical Healthcare. The main objective is to understand the underlying concepts and the assets of BI solutions with Pervasive characteristics.

In the eyes of the intensivists, the ever growing amount of available data concerning the patients, makes it each time more difficult for them to make a decision based on so many information. It is based on this ideal of improving the decision making process, that this work arises and Data Mining models were induced to predict if a patient will need to take a vasopressor, more specifically: Dopamine, Adrenaline or Noradrenaline. This work used real data provided by an Intensive Care Unit and collected in real-time. The data mining model were induced using data from vital sign monitors, laboratory analysis and information about the patient’s Electronic Health Record. This study was based in clinical evidences and provided very useful results with a sensitivity around 90%. These models will reduce the need of vasopressor drugs by helping intensivists to act and take accurate decision before the vasopressor be need by the patient. It will improve the patient condition because when the time comes the predicted necessity of the vasopressor will cease to exist due to the early care provided by the intensivist. The decisions can be for example change the therapeutic plan. Overall, the decision making process becomes more reliable and effective and the quality of care given to patients is better. © 2016 Penerbit UTM Press.

The gateway is composed by several agents able to collect a set of patients’ variables (vital signs, ventilation) across the network. The paper shows as example the ventilation acquisition process. The clients are installed in a machine near the patient bed. Then they are connected to the ventilators and the data monitored is sent to a multithreading server which using Health Level Seven protocols records the data in the database. The agents associated to gateway are able to collect, analyse, interpret and store the data in the repository. This gateway is composed by a fault tolerant system that ensures a data store in the database even if the agents are disconnected.

This procedure is used to support patients with respiratory diseases however in many cases it can provoke lung damages, Acute Respiratory Diseases or organ failure. With the goal to early detect possible patient breath problems a set of limit values was defined to some variables monitored by the ventilator (Average Ventilation Pressure, Compliance Dynamic, Flow, Peak, Plateau and Support Pressure, Positive end-expiratory pressure, Respiratory Rate) in order to create critical events. A critical event is verified when a patient has a value higher or lower than the normal range defined for a certain period of time. The values were defined after elaborate a literature review and meeting with physicians specialized in the area. This work uses data streaming and intelligent agents to process the values collected in real-time and classify them as critical or not. Real data provided by an Intensive Care Unit were used to design and test the solution. In this study it was possible to understand the importance of introduce critical events for Mechanically Ventilated Patients. In some cases a value is considered critical (can trigger an alarm) however it is a single event (instantaneous) and it has not a clinical significance for the patient. The introduction of critical events which crosses a range of values and a predefined duration contributes to improve the decision-making process by decreasing the number of false positives and having a better comprehension of the patient condition. © Springer International Publishing Switzerland 2016.}, note = {cited By 2; Conference of World Conference on Information Systems and Technologies, WorldCIST 2016 ; Conference Date: 22 March 2016 Through 24 March 2016; Conference Code:172089}, keywords = {Critical events; INTCare; Intensive care; Real time; Streaming data; Ventilated Patients, Data acquisition; Decision making; Intelligent agents; Intensive care units; Interoperability; Pulmonary diseases; Ventilation, Information systems}, pubstate = {published}, tppubtype = {inproceedings} } @inproceedings{Braga2016527, title = {Pervasive patient timeline for intensive care units}, author = {A.

Although the patient’s history and physical examination may denote good practice, some key information has to be obtained from valuation of the glomerular filtration rate, and the analysis of serum biomarkers. Indeed, chronic kidney sickness depicts anomalous kidney function and/or its makeup, i.e., there is evidence that treatment may avoid or delay its progression, either by reducing and prevent the development of some associated complications, namely hypertension, obesity, diabetes mellitus, and cardiovascular complications. Acute kidney injury appears abruptly, with a rapid deterioration of the renal function, but is often reversible if it is recognized early and treated promptly. In both situations, i.e., acute kidney injury and chronic kidney disease, an early intervention can significantly improve the prognosis. The assessment of these pathologies is therefore mandatory, although it is hard to do it with traditional methodologies and existing tools for problem solving. Hence, in this work, we will focus on the development of a hybrid decision support system, in terms of its knowledge representation and reasoning procedures based on Logic Programming, that will allow one to consider incomplete, unknown, and even contradictory information, complemented with an approach to computing centered on Artificial Neural Networks, in order to weigh the Degree-of-Confidence that one has on such a happening.

The lack of profitability of football betting website users has been stressed as a problem. In accordance with the stated arises here, an opportunity to explore. This lack gave origin to this research proposal, which is going to address the possibility of existing a way to support the users on their online bets, in order to improve their results and profitability. A football match could be analysed from the perspective of several types of statistical data, which do not have a direct influence on the final match result. This research work has the aim of helping to improve the performance of online football bets, by providing users statistical data that may be important to take into account, at the time of doing their own bets. In this work it was possible introduce data mining models which are able to predict 2-way results (home team win/draw or visitor team win) with 96,2 % of sensitivity and a good level of accuracy (74.8%).

This research seeks to explore a new way of presenting information about patients, based on the timeframe in which events occur. By developing an interactive Patient Timeline, intensivists will have access to a new environment in real-time where they can consult the patient clinical history and the data collected until the moment. The medical history will be available from the moment in which patients is admitted in the ICU until discharge, allowing intensivist to examine data regarding vital signs, medication, exams, among others. This timeline also intends to, through the use of information and models produced by the INTCare system, combine several clinical data in order to help diagnose the future patients' conditions. This platform will help intensivists to make more accurate decision. This paper presents the first approach of the solution designed. © 2015 The Authors.

The system is focused in identifying critic events from data streaming (e.g. vital signs and ventilation) which is particularly valuable for understanding the patient’s condition. This work aims to demonstrate the process of creating an intelligent system capable of operating in a real environment using streaming data provided by ventilators and vital signs monitors.

Complementarily, DSS produces several indicators to support clinical and management decisions. A recent data analysis revealed a bias in the classification of URG cases. Frequently, cases classified as URG correspond to ARGO. This misclassification has been studied by means of Data Mining (DM) techniques in order to improve the pre-triage model and to discover knowledge for developing a new triage system based on waiting times and on a 5-scale of classes.

However, a limitation still exists. The triage system is general and not specific to each case. Manchester Triage System is a reliable known system and is focused in the emergency department of a hospital. When applied to specific patients' conditions (such as pregnancy), it has several limitations. To overcome those limitations, an alternative triage system, integrated into an intelligent decision support system, was developed. The system classifies patients according to the severity of their clinical condition, establishing clinical priorities and not diagnosis. According to the urgency of attendance or problem type, it suggests one of three possible categories of the triage. This chapter presents the overall knowledge acquisition cycle associated with the workflow of patient arrival and the inherent decision making process. Results show that this new approach enhances the efficiency and the safety through the appropriate use of resources and by assisting the right patient in the right place, reducing the waiting triage time and the number in general urgency. © 2015 by IGI Global.

A set of Data Mining (DM) models has been developed using forecasting techniques and classification models to aid decision making by physicians about the appropriate, and most effective, therapeutic plan to adopt in specific situations. A combination of Decision Trees, Support Vector Machines and Naïve Bayes classifier were being used to generate the DM models. Confusion Matrix, including associated metrics, and Cross-validation were used to evaluate the models. Associated metrics used to identify the most relevant measures to predict sepsis level and treatment procedures include the analysis of the total error rate, sensitivity, specificity, and accuracy measures. The data used in DM models were collected at the Intensive Care Unit of the Centro Hospitalar do Porto, in Oporto, Portugal. Encapsulated within a supervised learning context, classification models were applied to predict sepsis level and direct the therapeutic plan for patients with sepsis. This work concludes that it was possible to predict sepsis level (2nd and 3rd) with great accuracy (accuracy: 100%), but not for the therapeutic plan (best accuracy level: 62.8%).

SS can automatically, in real-time and using online learning, provide a set of scores with a minimum human effort. SS is integrated in the Electronic Nursing Record (ENR) used for better comprehension of the patient condition through a set of information available: vital signs graphs, therapeutic plans, interventions, laboratory results and others. Those systems are supported by a pervasive platform for monitoring patient data anywhere and anytime. SS calculates the TISS-28 Score per day and nursing turn and the MEWS per minute, hour and day. These two new scores improve the understanding of the real condition of the patients. SS allows for obtaining automatically and in real-time the following scores: SAPS II, SAPS III, SOFA, GLASGOW, TISS28 and Mews anywhere and anytime. The development of SS only was possible due to a continuous and real-time execution of the data acquisition and data processing.

This study presents two data mining approaches to predict LOS in an ICU. The first approach considered the admission variables and some other physiologic variables collected during the first 24 hours of inpatient. The second approach considered admission data and supplementary clinical data of the patient (vital signs and laboratory results) collected in real-time. The results achieved in the first approach are very poor (accuracy of 73 %). However, when the prediction is made using the data collected in real-time, the results are very interesting (sensitivity of 96.104%). The models induced in second experiment are sensitive to the patient clinical situation and can predict LOS according to the monitored variables. Models for predicting LOS at admission are not suited to the ICU particularities. Alternatively, they should be induced in real-time, using online-learning and considering the most recent patient condition when the model is induced.}, note = {cited By 11; Conference of 6th International Conference on Knowledge Management and Information Sharing, KMIS 2014 ; Conference Date: 21 October 2014 Through 24 October 2014; Conference Code:114703}, keywords = {Clinical situations; INTCare; Length of stay; Online learning; Patient condition; Real time; Real-time data mining; Resources planning, Data mining; Forecasting; Knowledge management, Intensive care units}, pubstate = {published}, tppubtype = {inproceedings} } @inproceedings{Portela201487, title = {Pervasive and intelligent decision support in intensive medicine - The complete picture}, author = {F.

To overcome these constraints an integrated and pervasive system called INTCare has been deployed. This paper is focused in presenting the system architecture and the knowledge obtained by each one of the decision modules: Patient Vital Signs, Critical Events, ICU Medical Scores and Ensemble Data Mining. This system is able to make hourly predictions in terms of organ failure and outcome. High values of sensitivity where reached, e.g. 97.95% for the cardiovascular system, 99.77% for the outcome.

For this, was adopted the Cross-Industry Standard Process for Data Mining (CRISP-DM) methodology. Three distinct techniques were considered: Decision Trees (DT), Naïve Bayes (NB) and Support Vector Machine (SVM) to perform classification tasks. This work explored the possibility to predict the number of patient discharges using only the number of discharges veirifed in the past. The models developed are able to predict the number of patient discharges per week with acuity values ranging from ≈82.69% to ≈94.23%.

This paper presents the results obtained combining real-time data processing with ensemble approach in the intensive care unit of the Centro Hospitalar do Porto, Porto, Portugal. © 2013 Springer-Verlag.}, note = {cited By 27; Conference of 4th International Conference on Information Technology in Bio- and Medical Informatics, ITBAM 2013 ; Conference Date: 28 August 2013 Through 28 August 2013; Conference Code:99901}, keywords = {Artificial intelligence; Automobile drivers; Decision support systems; Forecasting; Health care; Information science; Intensive care units, Data mining models; Decision making process; Ensemble approaches; Ensemble strategies; Intelligent decision support; Intelligent decision support systems; Organ failure; Real-time data processing, Information technology}, pubstate = {published}, tppubtype = {inproceedings} } @inproceedings{Portela2013270, title = {Data mining for real-time Intelligent Decision Support System in intensive care medicine}, author = {F.

This chapter introduces a distributed data mining approach suited to grid computing environments based on a supervised learning classifier system. Five different tactics are explored for constructing the global model in a Distributed Data Mining (DDM) approach: Generalized Classifier Method (GCM), Specific Classifier Method (SCM), Weighed Classifier Method (WCM), Majority Voting Method (MVM), and Model Sampling Method (MSM).

When applied to specific patients' conditions (such as pregnancy), it has several limitations. To overcome those limitations, an alternative triage system, integrated into an intelligent decision support system, was developed. The system classifies patients according to the severity of their clinical condition, establishing clinical priorities and not diagnosis. According to the urgency of attendance or problem type, it suggests one of three possible categories of the triage. This chapter presents the overall knowledge acquisition cycle associated with the workflow of patient arrival and the inherent decision making process. Results show that this new approach enhances the efficiency and the safety through the appropriate use of resources and by assisting the right patient in the right place, reducing the waiting triage time and the number in general urgency. © 2013, IGI Global.}, note = {cited By 23}, keywords = {Clinical conditions; Decision making process; Emergency departments; Intelligent decision support; Intelligent decision support systems; Manchester; New approaches; Patients' conditions, Decision making; Diagnosis; Hospitals; Knowledge acquisition, Decision support systems}, pubstate = {published}, tppubtype = {inbook} } @inproceedings{Portela2013410, title = {Pervasive Ensemble Data Mining Models to Predict Organ Failure and Patient Outcome in Intensive Medicine}, author = {F.

This type of problems can culminate in the death of patient. In order to help the intensive medicine professionals at the exact moment of decision making, a Pervasive Intelligent Decision Support System called INTCare was developed. INTCare uses ensemble data mining to predict the probability of occurring an organ failure or patient death for the next hour. To assure the better results, a measure was implemented to assess the models quality. The transforming process and model induction are both performed automatically and in real-time.

In order to improve the DMP in ICU, a Pervasive Intelligent Decision Support System, called INTCare was deployed in the ICU of Centro Hospitalar do Porto in Portugal. This system altered the way information is collected and presented. Moreover, the tracking system deployed as a specific module of INTCare - Electronic Nursing Record (ENR) is made accessible anywhere and anytime. The system allows for the calculation of the critical events regarding fve variables that are typically monitored in an ICU. Specifically, the INTCare tracking system characterizes a grid that shows the events by type and duration, empowers a warning system to alert the doctors and promotes intuitive graphics that allow care providers to follow the patient care journey. User acceptance was measured through a questionnaire designed in accordance with the Technology Acceptance Model (TAM) and results of implementing the INTCare tracking system, and its interface are reported.

Many hospitals choose and to rely on RFID tracking systems to avoid the theft or loss of equipment, reduce the time spent looking for equipment, finding missing patients or staff, and issuing warnings about personnel access to unauthorized areas. The ability to successfully simulate the trajectory of an entity is very important to replicate what happens in RFID embedded systems. Testing and optimizing in a simulated environment, which replicates actual conditions, prevent accidents that may occur in a real environment. Trajectory prediction is a software approach which provides, in real time, the set of sensors that can be deactivated to reduce power consumption and thereby increase the system's lifetime. Hence, the system proposed here aims to integrate the aforementioned strategies - simulation and prediction. It constitutes an intelligent tracking simulation system able to simulate and predict an entity's trajectory in an area fitted with RFID sensors.

Indeed, there is a wide concern to the fact that an ineffi cient water management system may become one of the major drawbacks for a human-centered sustainable development process. The assessment of reservoir water quality is constrained due to geographic considerations, the number of parameters to be considered and the huge fi nancial resources needed to get such data. Under these circumstances, the modeling of water quality in reservoirs is essential in the resolution of environmental problems and has lately been asserting itself as a relevant tool for a sustainable and harmonious progress of the populations. The analysis and development of forecast models, based on Artifi cial Intelligence-based tools and the new methodologies for problem solving, has proven to be an alternative, having in mind a pro-active behavior that may contribute decisively to diagnose, preserve, and rehabilitate the reservoirs. In particular, this work describes the training, validation and application of Artifi cial Neural Networks (ANNs) and Decision Trees (DTs) to forecast the water quality of the Odivelas reservoir, in Portugal, over a period of 10 years. The input variables of the ANN model are chemical oxygen demand (COD), dissolved oxygen (DO), and oxidability and total suspended solids (TSS), while for the DT the inputs are, in addition to those used by ANN, the Water Conductivity and the Temperature. The performance of the models, evaluated in terms of the coincidence matrix, created by matching the predicted and actual values, are very similar for both models; the percentage of adjustments relative to the number of presented cases is 98.8% for the training set and 97.4% for the testing one. © 2012 WIT Press.}, note = {cited By 10}, keywords = {Artificial Intelligence; Chemical Oxygen Demand; Data Processing; Decision Theory; Mathematical Models; Neural Networks; Reservoirs; Water Management; Water Quality, Chemical oxygen demand; Data mining; Decision trees; Forestry; Neural networks; Neurons; Reservoirs (water); Water management, Coincidence matrixes; Decision trees (DTs); Environmental problems; FORECAST model; Input variables; Neuronal networks; Portugal; Reservoir water quality; Total suspended solids; Training sets; Water conductivity; Water management systems; Water quality modeling, Water quality}, pubstate = {published}, tppubtype = {article} } @article{Vicente2012310, title = {Prediction of water quality parameters in a reservoir using artificial neural networks}, author = {H.

To this picture it should be added the latency times between the sampling moment and the instant that portrait the results of the laboratory analyses. However, new approaches to problem solving, namely those borrowed from the Artifi cial Intelligence arena have proven their ability and applicability in terms of simulation and modeling of the physical phenomena. Indeed, Artifi cial Neural Networks (ANNs) capture the embedded spatial and unsteady behavior in the investigated problem, using its architecture and nonlinearity nature, when compared with the other classical modeling techniques. This work describes the training, validation, and application of ANNs models for computing the oxidability and total suspended solids (TSS) levels in the Monte Novo reservoir, in Portugal, over a period of 15 years. Different network structures have been elaborated and evaluated. The performance of the ANNs models was assessed through the coeffi cient of determination (R2), mean absolute deviation, mean squared error, and bias computed from the measured and model calculated values of the dependent variables. Goodness of the model fi t to the data was also evaluated through the relationship between the errors and model computed values of oxidability and TSS. The ANNs selected to predict the oxidability from pH, conductivity, dissolved oxygen (DO), water temperature, and volume of water stored in reservoir has a 4-11-5-1 topology, while the network selected to predict the TSS has a 5-6-5-1 topology.

The main purpose of this system is to help the doctors and nurses making decisions more proactively based on the prediction of the organ failure and the outcome of the patients. To assure the adoption of INTCARE by the doctors and by the nurses, several requirements had taken into account: process dematerialization (information is now in electronic format); interoperability among the systems (the AIDA platform was used to inter operate with other information systems); online data acquisition and real-time processing (a set of software agents has been developed to accomplish these tasks). A technology acceptance methodology has been followed in the Intensive Care Unit (ICU) of Centro Hospitalar do Porto in order to assure the most perfect alignment between the functional and technical characteristics of INTCARE and the user expectations. Results showed that the ICU staff is permeable to the system. In general more than 90 % of the answers are scored with 4 or 5 points which gives a good motivation to continue the work. © 2012 EUROSIS-ETI.}, note = {cited By 4; Conference of 26th European Simulation and Modelling Conference, ESM 2012 ; Conference Date: 22 October 2012 Through 24 October 2012; Conference Code:104382}, keywords = {Artificial intelligence; Decision support systems; Interoperability; Modal analysis; Nursing; Technology, INTCARE; Intelligent decision support systems; Intensive care medicines; Real-time; Technology acceptance, Intensive care units}, pubstate = {published}, tppubtype = {inproceedings} } @inproceedings{Portela2011241, title = {Knowledge discovery for pervasive and real-time Intelligent Decision Support in intensive care medicine}, author = {F.

This paper proposes a representative approach to a simulated area filled with sensors and travelled by an object. The object has an initial and end points and does random movement between them. The remaining unknown path must be provided by the sensors and the prevision module while error metrics must be calculated dynamically to help the prediction of the followed path. In this scenario, a trajectory is a path that an entity follows through space between iterations, and it can be represented as a set, of coordinates sorted over time. The level of accuracy needed for the prediction model and objectives of this environment required a grid like representation. The presented solution is a multiple dimension structure that covers the environ-ment variables and entities of a move within the environment. An application has been developed to simulate a censored place driven by a random trajectory object and to calculate as accurate as possible the path of the object. ©2011 EUROSIS-ETI.}, note = {cited By 1; Conference of 25th European Simulation and Modelling Conference, ESM 2011 ; Conference Date: 24 October 2011 Through 26 October 2011; Conference Code:104378}, keywords = {Data mining; Forecasting; Modal analysis; Radio frequency identification (RFID); Sensors, Error metrics; Evolutionary approach; Evolutionary intelligence; Multiple dimensions; Object trajectories; Prediction model; Space between; Trajectory prediction, Trajectories}, pubstate = {published}, tppubtype = {inproceedings} } @inproceedings{Peixoto2011399, title = {AASYS - Appointment alert system: An open-source-based software to improve show rates in a health care unit}, author = {H.

In recent years, many formalisms have been proposed tacking the matter of uncertain, incomplete in logic programs and databases. However, qualitative models and qualitative reasoning have been around in Artificial Intelligence research for some time, in particular due the growing need to offer support in decision-making processes. The evaluation of knowledge that stems out from logic programs becomes a point of research. The Quality-of-Information concept demonstrated their applicability in many dynamic environments and for decision making purposes. In this paper we present an illustrative example of the inference process in decisions in healthcare environments. Under the Extended Logic Programming paradigm to knowledge representation and reasoning, we present the evolutive perspective of the inference process to achieve logical programs (or theories) corresponding to the best theorems to solve a problem or take a decision. For the evaluation of the best theories we use a quantification of the quality-of-information that stems out from a logic program. © 2010 IEEE.}, note = {cited By 1; Conference of 9th IEEE/ACIS International Conference on Computer and Information Science, ICIS 2010 ; Conference Date: 18 August 2010 Through 20 August 2010; Conference Code:82351}, keywords = {Computer software selection and evaluation; Decision making; Decision support systems; Decision theory; Information science; Intelligent systems; Knowledge representation; Logic programming, Quality control}, pubstate = {published}, tppubtype = {inproceedings} } @inproceedings{Miranda201095, title = {Modelling intelligent behaviours in multi-agent based HL7 services}, author = {M.

Staging reports are usually performed by oncologists but sometimes are also done by physicians not specialized in this area. In this paper, it is presented a multi-agent system to support group decision that helps meeting participants to reach and to justify a solution. With the increasing use of web applications to perform the Electronic Medical Record on healthcare facilities, this system has the potential to be easily integrated in order to support the medical and clinical e-learning and to improve patient assistance. In fact, the usual need for documentation and specific information by the medical staff can be easily provided by these systems, making a new steep towards a paper free healthcare system. © ICST Institute for Computer Sciences, Social Informatics and Telecommunications Engineering 2009.}, note = {cited By 16; Conference of 1st International Conference on Electronic Healthcare, eHealth 2008 ; Conference Date: 8 September 2008 Through 9 September 2008; Conference Code:85965}, keywords = {Cancer staging; Classification system; Common languages; Ehealth; Electronic medical record; Group decision; Health-care system; Healthcare facility; Specific information; Staging of caner; WEB application, Decision making; Diseases; E-learning; Health care; Intelligent agents; Medical computing; Multi agent systems; User interfaces, Decision support systems}, pubstate = {published}, tppubtype = {inproceedings} } @inproceedings{Duarte2009115, title = {Agent-based group decision support in medicine}, author = {J.

Focusing on the elderly care, as the human capacity of memorizing events decreases over time, it is intended to promote an active ageing lifestyle for the elderly, where memory assistance tools are vital component.

Indeed, a significative number of healthcare institutions have extensive Electronic Health Records (EHR), collected over several years for clinical and teaching purposes, but are uncertain as to the proper circumstances in which to use them to improve the delivery of care to the ones in need. Research Ethics Boards in Portugal and elsewhere in the world are grappling with these issues, but lack clear guidance regarding their role in the creation of and access to EHRs. However, we feel we have an effective way to handle Medical Ethics if we look to the problem under a structured and more rational way. Indeed, we felt that physicians were not aware of the relevance of the subject in their pre-clinical years, but their interest increase when they were exposed to patients. On the other hand, once EHRs are stored in machines, we also felt that we had to find a way to ensure that the behavior of machines toward human users, and perhaps other machines as well, is ethically acceptable. Therefore, in this article we discuss the importance of machine ethics and the need for machines that represent ethical principles explicitly. It is also shown how a machine may abstract an ethical principle from a logical representation of ethical judgments and use that principle to guide its own behavior. © IFIP International Federation for Information Processing 2009.}, note = {cited By 6; Conference of 9th IFIP WG 6.1 Conference on e-Business, e-Services and e-Society, I3E 2009 ; Conference Date: 23 September 2009 Through 25 September 2009; Conference Code:98939}, keywords = {Abstracting; Electronic commerce; Felt; Intelligent agents, Electronic health record; Ethical principles; Health informations; Healthcare institutions; Logical representations; medical ethics; Morality; Research ethics, Philosophical aspects}, pubstate = {published}, tppubtype = {inproceedings} } @inproceedings{Miranda2009313, title = {An agent-based architecture for cancer staging}, author = {M.

The question is, how far we can go in considering computer intelligence and autonomy, how can we legally deal with a new form of electronic behaviour capable of autonomous action? In the field of contracting, through Intelligent Electronic Agents, there is an imperious need of analysing the question of expression of consent, and two main possibilities have been proposed: considering electronic devices as mere machines or tools, or considering electronic devices as legal persons. Another possibility that has been frequently mentioned consists in the application of the rules of agency to electronic transactions. Meanwhile, the question remains: would it possible, under a Civil Law framework, to apply the notions of "legal personhood" and "representation" to electronic agents? It is obvious that existing legal norms are not fit for such an endeavouring challenge.

In this paper it will be presented a logical theory of Situation Awareness (SA) and discusses the methods required for developing an objective measure of SA within the context of a simulated medical environment, as the one referred to above.

Its application to Virtual Enterprises requires an analysis of the interactions among agents, frameworks and users, as well as technical and legal analysis, in order to discover the rules to be applied, to solve a particular problem under a prospective scenario. Credibility, trust and security issues must be taken under consideration, especially concerning authenticity, confidentiality, integrity and nonrepudiation. In order to increase the use of agents in Virtual Enterprises, besides the analysis and research of legal solutions in the commercial arena, it is essential to assure that agents will meet requirements of credibility and trust, insuring a transparent and secure way for their commercial acting, now capable of generating legal relations. This paper shows how to construct a dynamic virtual world of complex and interacting entities or agents, in which fitness is judged by a quality of information criterion. © 2005 by International Federation for Information Processing.}, note = {cited By 19; Conference of IFIP TC5 WG 5.5 6th IFIP Working Conference on Virtual Enterprises, PRO-VE 2005 ; Conference Date: 26 September 2005 Through 28 September 2005; Conference Code:105830}, keywords = {Artificial intelligence, Interacting entities; ITS applications; Legal solutions; Non-repudiation; Quality of information; Trust and security; Virtual enterprise; Virtual worlds, Virtual corporation}, pubstate = {published}, tppubtype = {inproceedings} } @inproceedings{Machado2005199, title = {Web-based simulation in medicine}, author = {J.

Western laws usually recognize Corporate Bodies as having legal personality and capacity for every right and obligation needed or convenient to the prosecution of its social goals. But can we foresee a similar attribution of such a regime to software agents? In other words, are intelligent software agents capable of being personified? One of the main characteristics of a personality is the existence of a physical being or organization provided with its own will. In that sense, intelligent software agents are quite close to human beings. Indeed, they have a physical existence, and they have the capability of learning and of having a will of their own. © 2004 Springer Science + Business Media, Inc.}, note = {cited By 6; Conference of IFIP TC5/WG5.5 5th Working Conference on Virtual Enterprises, PRO-VE 2004 ; Conference Date: 22 August 2004 Through 27 August 2004; Conference Code:105745}, keywords = {Human being; Intelligent software agent; Legal personality; Social goals, Software agents, Virtual corporation}, pubstate = {published}, tppubtype = {inproceedings} } @inproceedings{Novais2003703, title = {Argumentative procedures in e-commerce environments}, author = {P.

The notion of compound contexts reflects the beliefs, desires, intentions and obligations, among others, that depend on the problem, leading to a variety of dynamic context formations.
