Ad-Hoc Mono- and Bilingual Retrieval Experiments at the University of Hildesheim

This paper reports on our participation in CLEF 2005‘s ad-hoc multi-lingual retrieval track. The ad-hoc task introduced Bulgarian and Hungarian as new languages. Our experiments focus on the two new languages. Naturally, no relevance assessments are available for these collections yet. Optimization was mainly based on French data from last year. Based on experience from last year, one of our main objectives was to improve and refine the n-gram-based indexing and retrieval algorithms within our system.
