ITC-irst at CLEF 2003: Monolingual, Bilingual, and Multilingual Information Retrieval

This paper reports on the participation of ITC-irst in the Cross Language Evaluation Forum 2003; in particular, in the monolingual, bilingual, small multilingual, and spoken document retrieval tracks. Considered languages were English, French, German, Italian, and Spanish. With respect to our CLEF 2002 system, the statistical models for bilingual document retrieval have been improved, more languages have been considered, and a novel multilingual information retrieval system has been developed, which combines several bilingual retrieval models into a statistical framework. As in the last CLEF, bilingual models integrate retrieval and translation scores over the set of N-best translations of the source query.
