Abstract

The paper describes our participation in monolingual tasks at CLEF 2006. We submitted results for the following languages: English, French, Portuguese and Hungarian.We focused on studying different weighting schemes (okapi and dfr) and retrieval strategies (passage retrieval and document retrieval) to improve retrieval performance. After an analysis of our experiments and of the official results at CLEF 2006, we achieved considerably improved scores by using different configurations for different languages (French, Portuguese and Hungarian).
