Abstract

This paper reports information retrieval experiments carried out within the CLEF 2005 ad-hoc multi-lingual track. The experiments focus on the two new languages Bulgarian and Hungarian. No relevance assessments are available for these collections yet. Optimization was mainly based on French data from CLEF 2004. 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.
