Visiting Researcher

I work at the University of Zaragoza (Spain) and my interests include ontologies, sense discovering and semantic disambiguation techniques.
We have been working recently on discovering the possible senses of a group of user keywords among a pool of online ontologies (applying integration techniques when the senses are considered very similar).
Also we have ideated a multi-ontology disambiguation method that is independent of a single lexical resource. We use it to discover the most suitable keyword senses according to the context.
My work at KMi was to study possible applications of these techniques into PowerAqua and other related projects.
