Combining Evidence for Cross-Language Information Retrieval

This paper describes the official runs of our team for CLEF 2002. We took part in the monolingual tasks for each of the seven non-English languages for which CLEF provides document collections (Dutch, Finnish, French, German, Italian, Spanish, and Swedish). We also conducted our first experiments for the bilingual task (English to Dutch, and English to German), and took part in the GIRT and Amaryllis tasks. Finally, we experimented with the combination of runs.
