An effective Malayalam information retrieval system using query expansion

Malayalam, a classical language in India, is spoken by over 40 million people. This paper proposes an effective information retrieval system for Malayalam, which retrieve Malayalam documents relevant to the user's information need. The proposed system improves effectiveness by considering synonyms and negations of the terms specified in the query. Though the evaluation of the system is performed over a small corpus, the results are promising. The proposed system is thus relevant for various natural language processing tasks in an highly agglutinative language like Malayalam.
