The group started its activities under Prof. Sivaji Bandyopadhyay ( The main goal of the group is to pursue application-oriented basic research and to develop real-life applications. Research is being carried out in the areas of Headline Generation, Headline Translation, Document Translation and Multilingual Multidocument Summarization with the objective of providing natural access to Internet resources. A prototype system that translates English sentences to Bengali using hybrid techniques has been developed. Methodologies for identification and resolution of anaphors and coreferences in the News documents are being developed.
A Cross Language Database System in Bengali and Hindi has been developed. The other areas where the group is actively pursuing research are: Spell-Checker Design, Natural Language Interfaces to Databases, Open Domain Question Answering, Named Entity Recognition and Word Sense Disambiguation.
Prof. Bandyopadhyay got the University Grants Commission Research Award for the IXth Plan Period to work in the area of machine translation. He was a member of the Program Committee of an International Workshop on Example Based Machine Translation System held during MT SUMMIT VIII at Spain in 2001. He is a member of the Association for Computational Linguistics (ACL), International Association for Machine Translation (IAMT) and the Asia-Pacific Association for Machine Translation (AAMT).
