Abstract
This report describes the work done by the Information Retrieval Group at Océ Technologies B.V., for the 2002 edition of the Cross-Language Evaluation Forum (CLEF). We participated in the mono, cross and multi-lingual tasks, using BM25 for ranking, Ergane, Logos and BabelFish for translation and the Knowledge Concepts semantic network for stemming and morphological expansion. We performed a brute-force parameter search using the 2001 topics and relevance assessments to determine for each language the pair of BM25 parameters that yielded the highest average precision. These parameters were used to query the 2002 topics.
