Abstract: Fusion and optimization based relevance judgements have proven to be successful strategies in information retrieval. In this year’s CLEF campaign we applied these strategies to multilingual retrieval with four languages. Our fusion experiments were carried out using freely available software. We used the snowball stemmers, internet translation services and the text retrieval tools in Lucene and the new MySQL.
