Evaluating semantic textual similarity in clinical sentences using deep learnin...

The wide adoption of electronic health records (EHRs) has fostered an improvement in healthcare quality, with EHRs currently representing a major source of medical information. Nevertheless, this process has also brought new challenges to the medical environment since the facilitated replication of information (e.g. using copy-paste) has resulted in less concise and sometimes incorrect information, which hinder...

Clinical concept normalization on medical records using word embeddings and heu...

Electronic health records contain valuable information on patients' clinical history in the form of free text. Manually analyzing millions of these documents is unfeasible and automatic natural language processing methods are essential for efficiently exploiting these data. Within this, normalization of clinical entities, where the aim is to link entity mentions to reference vocabularies, is of utmost importanc...

Biomedical word sense disambiguation with word embeddings

There is a growing need for automatic extraction of information and knowledge from the increasing amount of biomedical and clinical data produced, namely in textual form. Natural language processing comes in this direction, helping in tasks such as information extraction and information retrieval. Word sense disambiguation is an important part of this process, being responsible for assigning the proper concept ...

Evaluation of word embedding vector averaging functions for biomedical word sen...

The biomedical lexicon contains a large amount of term ambiguity, which hinders correct identification of concepts and reduces the accuracy of semantic indexing and information retrieval tools. Previous work on biomedical word sense disambiguation has shown that supervised machine learning leads to better results than knowledge-based approaches. However, machine learning approaches require the availability of s...

Machine learning with word embeddings applied to biomedical concept disambiguation

Artificial Intelligence (AI) has grown in the last years and it has many applications. Natural Language Processing is one of the AI tasks, which has the objective to endow the machines the capability of understanding human language. This is an important process due to the amount of information stored in textual form. There is a growing need for automatic extraction of knowledge, and NLP comes in this direction ...

Música genómica

Dada a grande informação genética já descoberta ao longo do tempo, a música genómica permite uma análise um pouco invulgar, que consiste na conversão de sequências de ADN em música. Na expectativa que será possível detetar através da audição, caraterísticas interessantes no ADN. Vários trabalhos já foram realizados nesta área. O objetivo principal deste trabalho consiste no desenvolvimento de algoritmos adequad...

CIRea2012 - Conferência Internacional sobre Reabilitação de Estruturas Antigas de Alvenaria, Universidade Nova de Lisboa, 4 Maio 2012, 29-38; A nova versão da norma NP EN 459-1:2011 de cais de construção apresenta uma nova classificação das cais com propriedades hidráulicas. Esta situação impõe uma reclassificação e, por vezes, uma reformulação de muitas cais hidráulicas que, segundo a versão anterior da norma ...

Streptococcus pyogenes toxic-shock syndrome.

Recently there has been an exponential increase in invasive infections caused by Streptococcus ß hemolyticus group A. In about one third of cases they are complicated by toxic shock syndrome, characterized by septic shock and multiorgan failure. The authors, by their rarity, report a case of bacteraemia caused by Streptococcus pyogenes complicated by toxic shock syndrome.; Recently there has been an exponential...
