Research Fellow
I have worked on the AKT, Dot.Kom, and ELeGI projects. Currently I am interested in expert search in organizational intranets. A novel two-stage language model is proposed for effective expert search, and achieved excellent results in TREC Enterprise Track Expert Search task.
I have led the development of the CORDER (Community Relation Discovery by Named Entities) system which measures associations between named entities in a text corpus by integrating their occurrences, distances in text, and frequencies in documents.
I authored the ESpotter tool, which provides effective named entity recognition for a domain by adapting its lexicon and patterns to the domain through a URL tree.
