Abstract

For our fourth participation in the CLEF evaluation campaigns, our first objective was to propose an effective and general stopword list and a light stemming procedure for the Portuguese language. Our second objective was to obtain a better picture of the relative merit of various search engines when processing documents in the Finnish and Russian languages. Finally, based on the Z-score method we suggested a data fusion strategy intended to improve monolingual searches in various European languages.
