More than three millions research articles have been written about proteins and Protein-Protein Interactions (PPI). The present work describes a plausible architecture and some preliminary experiments of our Protein-Protein Interaction Information Extraction system, PPIEs. The promising results obtained suggest that the approach deserves further efforts. Some important aspects that need to be i...

In this paper, we apply Semantic Web technologies to the creation of an improved search engine over legal and public administration documents. Conventional search strategies based on syntactic matching of tokens offer little help when the users’ vocabulary and the documents’ vocabulary differ. This is often the case in public administration documents. We present a semantic search tool that fill...

Controlled Medical Vocabularies (CMVs) have been studied identify and characterize organized sets of well-specified semantic relationships in the biomedical domain. Results of research on both hierarchical and non-hierarchical associative relationships in existing CMVs are being used to enrich ontological content through the discovery of subclasses, attributes, and relationships, and to enhance...

Problem lists are tools to improve patient management. In the medical record, they connect diagnoses to therapy, prognosis, and psychosocial issues. Computer-based problem lists enhance paper-based approaches by enabling cost-containment and quality assurance applications, but they require clinically expressive controlled vocabularies. Because existing controlled vocabularies do not represent p...
