Abstract
A patient's health literacy has a direct impact on their health, but more than a third of the USA population has "basic" or "below basic" levels of health literacy. An individual's wellbeing is also affected by the communication with their physician, as the use of technical terminology may hinder the patient's understanding. A patient's ability to, later on, recall or retrieve helpful information could reduce these comprehension problems and this can be improved by a good management of personal health information. To help overcome some of these problems, we created HealthTalks, a mobile app that empowers the patients, easing their daily health tasks and self-care ability. It does so by recording the audio of a medical appointment, transcribing its dialogue, giving more information about medical concepts employed, and allowing information associated with medical appointments to be easily managed by the patient. Usability tests were conducted with elderly people, ranging from the icons used to the general user experience. Results were very positive, with users accomplishing most tasks successfully and often with the least amount of clicks. We also evaluated the speech recognition software used, Google Cloud Speech API, reaching an error rate of 12 percent in medical texts.

Abstract
The importance of research data management is widely recognized. Dendro is an ontology-based platform that allows researchers to describe datasets using generic and domain-specific descriptors from ontologies. Selecting or building the right ontologies for each research domain or group requires meetings between curators and researchers in order to capture the main concepts of their research. Envisioning a tool to assist curators through the automatic extraction of key concepts from research documents, we propose 2 concept extraction methods and compare them with a term extraction method. To compare the three approaches, we use as ground truth an ontology previously created by human curators.

Abstract
This paper reports the participation of the InfoLab at the TREC Precision Medicine Track 2018. InfoLab is an informal group that brings together researchers with interest in the information area and is located at Faculty of Engineering of University of Porto. The experiments made in this participation include query expansion approaches for the disease and gene concepts. The expansion of the disease terms was done using Unified Medical Language System (UMLS). UMLS is a repository that provides the mapping between a large number of vocabularies. The gene terms were expanded using Ensembl. Ensembl provides a genome browser that maps genes to their synonyms. An additional layer was developed on top of Terrier to provide the execution of a large batch of experiments. Multiple runs were evaluated in order to measure the influence of each expansion approach. © 2018 Copyright held by the owner/author(s).

Abstract
O Repositório Aberto da UAb, como polo de agregação de publicações científicas em acesso aberto, não pode deixar de albergar e divulgar a produção científica em língua portuguesa dos docentes e investigadores da UAb. Sendo que a maioria das publicações, e aquelas que efetivamente têm maior relevância no currículo dos autores, são escritas em língua inglesa, a publicação em português é importante pela divulgação da ciência junto de populações que dominam menos o inglês, mas com grande potencial científico. Além disso, faz juz à matriz fundacional da Universidade Aberta, ao promover o uso da língua e a divulgação da sua atividade no espaço lusófono. Neste texto, analisamos o panorama da publicação científica em português na área da Informática, e apresentamos a Revista de Ciências da Computação, primeira revista científica em acesso aberto da UAb. A revista insere-se numa estratégia e política institucional de recursos abertos (REA), promovendo o acesso e a disseminação junto dos falantes de língua portuguesa espalhados pelo mundo.
