Abstract

This paper presents the ITC-irst Multilingual Question Answering system Diogene. The system was used successfully on the CLEF-2003, TREC-2003, TREC-2002 and TREC-2001 QA tracks. Diogene relies on a classical three-layer architecture: question processing, document retrieval, answer extraction and validation. Diogene uses MultiWordNet [8] (http:// multiwordnet.itc.it) which facilitates the transfer of knowledge between languages. For answer validation we used the Web. This year we also used a set of linguistic templates for answering specific questions like definition questions, location questions, and a subset of who-is and what-is questions. Diogene participated in both the monolingual Italian-Italian task and in the cross-language Italian-English task. We also collaborated with the Bulgarian Academy of Sciences in the cross-language Bulgarian-English QA task.
