Abstract
We describe the participation of the University of Amsterdam in the Question Answering track at CLEF 2004. We took part in the monolingual Dutch task and, for the first time, also in the bilingual English to Dutch task. This year’s system is a further elaboration and refinement of the multi-stream architecture we introduced last year, extended with improved candidate answer re-ranking and filtering, and with additional answer finding strategies. We report the evaluation results for the whole system and its various components. The results indicate the recall-oriented approach to QA is an effective one.
