eHealth Context Inference - A Review of Open Source Frameworks Initiatives

Authors: Arsénio Reis , Dennis Paulino , Paulo Martins , Hugo Paredes and João Barroso

Affiliation: INESC TEC and University of Trás-os-Montes e Alto Douro, Portugal

Digital Object Identifier: 10.5220/0006752707070714

Proceedings of AI4Health 2018, ISBN: 978-989-758-281-3

Quick Abstract

The collection of health and fitness longitudinal data can be used to model disease progression and shape new algorithms to diagnose and predict health hazards. Continuously tracking vital signs, in particular heart rate and skin temperature, can be very informative by using models and algorithms to predict and notify the user about when he might be falling ill. With the current wearable devices and the proper algorithms, the individual can be permanently monitored, which might be much more interesting than a one-off reading comparison with the population average, made by a doctor. It would be possible to intervene earlier and to prevent somebody from becoming seriously ill. From a broader perspective, the knowledge about a user’s health can be considered as an element of that user’s context and be used by context aware applications to provide higher value to the user. After the trivialization of the data acquisition sensors, wearable devices, and raw data, the next logical step is the development of contained software components that can infer and produce knowledge from the raw data. These components and the knowledge they produce can be used by all sorts of applications in order to further customize their usage by a specific user. Customization and context awareness, in regard to health, is a wide field for research and there are a multitude of proposals for models and algorithms. In this review work we searched for software components (frameworks, software libraries, etc.), freely available and that can be used as building blocks for other computer systems by software developers.

Quick Abstract

Higher education is a complex business including very different process. At its core are the teaching and research processes and along the edge of the business model are the administrative processes, targeted to the students and alumni. Some of these processes translate into services that must be available during the whole life of the users and the institutions. For example, a higher education institution is expected to issue diplomas during the whole lifetime of its former students. In this context, we’ve been working in order to use the current e-government infrastructure of electronic services as building blocks for some of the features of the higher education institution electronic services. This work proposes the adoption of a set of those services. We’ve concluded a successful testing stage and expect to deploy a full production system very soon.

Rule-based System Enriched with a Folksonomy-based Matcher for Generating Information Integration Alignments

Topics: Ontology Matching and Alignment; Integration and Interoperability

Authors: Alexandre Gouveia ¹ , Nuno Silva ¹ and Paulo Martins ²

Affiliations: ¹ Polytechnic of Porto, Portugal , ² University of Trás-os-Montes e Alto Douro and Polytechnic of Porto, Portugal

Digital Object Identifier: 10.5220/0006505302110218

Proceedings of KEOD 2017/IC3K, ISBN: 978-989-758-272-1

Quick Abstract

Ontology matchers establish correspondences between ontologies to enable knowledge from different sources and domains to be used in ontology mediation tasks (e.g. data transformation and information/ knowledge integration) in many ways. While these processes demand great quality alignments, even the best-performing alignment needs to be corrected and completed before application. In this paper, we propose a rule-based system that improves and completes the automatically-generated alignments into fully-fledged alignments. For that, the rules capture the pre-conditions (existing facts) and the actions to solve each (ambiguous) scenario, in which automatic decisions supported by a folksonomy-based matcher are adopted. The evaluation of the proposed system shows the increasing accuracy of the alignments.

Authors: João de Sousa e Silva ¹ , Ramiro Gonçalves ¹ and António Pereira ²

Affiliations: ¹ Universidade de Trás-os-Montes e Alto Douro, Portugal , ² Instituto Politécnico de Leiria, Portugal

Digital Object Identifier: 10.5220/0005996102720275

Proceedings of ICSOFT-EA 2016/ICSOFT, ISBN: 978-989-758-194-6

Quick Abstract

Digital accessibility is recognized as a fundamental tool for an egalitarian society. Nevertheless, software accessibility is an under addressed topic in the discipline of software engineering and the academy in general. As a result, its development and implementation is compromised. This problem is depicted here with the help of some experiments that shows the poor attention which is dedicated to this topic. Some hypotheses that try to explain this problem are formulated, and some possible solutions are debated. As a conclusion, some insights are given and a new possible researched avenue is presented.

Digital Object Identifier: 10.5220/0003517400690072

Proceedings of ICE-B 2011/ICETE, ISBN: 978-989-8425-70-6

Quick Abstract

On this paper we proceed to the analysis of the means of obtaining customer feedback through the Internet. Keeping demanding customers as well as attract new ones, has always been a major concern for the majority of the companies. Knowing what customers think is an important part of developing products and services, and differentiating factor against the competition. Obtaining customer feedback through the Internet can be considered more cost efficient and accessible, when compared to more traditional means. This work results from a study that identified the means of obtaining customer feedback, on the websites of the Portuguese companies with the biggest business volume.

PORTUGUESE WEB ACCESSIBILITY SNAPSHOT - Status of the Portuguese Websites Regarding Accessibility Levels

Topic: Internet HCI: Web Interfaces and Usability

Authors: Ramiro Gonçalves , José Martins , Manuel Martins , Jorge Pereira and Henrique Mamede

Affiliation: GECAD - University of Trás-os-Montes e Alto Douro, Portugal

Digital Object Identifier: 10.5220/0002905602230226

Proceedings of ICEIS 2010, ISBN: 978-989-8425-08-9

Quick Abstract

The Internet is extremely important for the publishing of information and for the interaction between the society elements. Due to this, it’s essential that the web presents itself accessible to all, including those with any kind of disability. An accessible web may help the handicapped citizens interact with the society in a more active way. This paper presents a study made with a universe of 777 Portuguese biggest enterprises, using a W3C referenced tool (SortSite), and presents some statistical results according to the Portuguese Classification of the Enterprises Activities. The achieved results present a serious troubled reality that’s preventing the disabled citizens from having the same access rights to the World Wide Web as the “non-disabled” citizens.

Digital Object Identifier: 10.5220/0002858702480251

Proceedings of WEBIST 2010, ISBN: 978-989-674-025-2

Quick Abstract

Web accessibility is growing in importance as each day goes by. Alongside with this growth, also the need of access to web resources, by those with some sort of disability, is increasing. The web is very important for spreading information and for the interaction between the various society elements. Given this, it’s mandatory that the web presents itself as a totally accessible resource, so that it can help the disable citizens in their integration within the society. This obligation should be even bigger for the enterprises because, in their majority, the web is used as a marketing and business platform. This document is meant to be a position paper regarding the comparison of results between web accessibility evaluations of the Portuguese websites using version 1 and version 2 of the W3C Web Content Accessibility Guidelines.

Quick Abstract

It is well recognized that e-business supports all parts of an organization’s value chain, and offer valuable competitive advantages to firms. It is imperative for an organization to identify potential constraints to e-business in order to minimize the risk derived from its e-business initiative. Hence, in this paper, we explore a range of constraints that the literature suggests influences e-business evolution, so that organizations could be better equipped in anticipating any difficulties while in progress through their e-business initiatives. Thirteen hypotheses were formulated and tested. Questionnaires were applied to investigate the research problem. It was administered to 1000 managing directors of the biggest (according to the amount of business) Portuguese enterprises. Results suggest that organizational constraints are more critical, such as, conflict with traditional trading partners, conflict with traditional business and e-business initiatives, reengineering business processes and resistance to change, among other.

Affiliation: UTAD University, Portugal

Digital Object Identifier: 10.5220/0002157301420147

Proceedings of ICEIS 2009, ISBN: 978-989-8111-88-3

Quick Abstract

The use of the web is quickly spreading to the majority of the society. In many countries the use of the web in government services, education and training, commerce, news, citizenship, health and entertainment is significantly increasing. The web is extremely important for the dissemination of information and the interaction between the various society elements. Due to this, it’s essential that the web presents itself accessible to all, including those with any kind of disability. An accessible web may help the handicapped citizens in their interaction with the society. With this in mind, an evaluation of the accessibility levels of the Portuguese websites is, essential, for an assumption on the availability of these websites to all disabled citizens.
