== Research Interest ==
My primary research interests are Information Retrieval, Natural Language Processing, Machine Learning and their intersection. In particular, I am interested in mining Collaboratively Constructed Semantic Resources (specially Wikipedia as a multilingual, huge, popular encyclopedia and Wiktionary as Wikipedia's lexical companion) that go beyond the typical Search Engines to teach them how to understand text documents and user's information needs in order to search smarter. I am also interested in understanding how current models scale to very large collections, such as WWW. Any task that is currently addressed with IR and NLP could use the mentioned approach to think smarter. Currently, my active research interest is semantic representation of textual documents using Concept Graph analysis from Wikipedia Concept Space. On the other hand, I'm trying to build "Wikipedia Concept Repository" in order to embed in any free text search engines and help them to understand documents and queries. ...more== Educational Background ==
