This paper reports on the participation of ITC-irst in the 2003 campaign of the Cross Language Evaluation Forum for the monolingual, bilingual, and small multilingual tasks. The languages considered were English, French, German, Italian, and Spanish. With respect to the ITC-irst system presented at CLEF 2002, 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.
