Experiments with the Eurospider Retrieval System for CLEF 2001

Eurospider participated in both the multilingual and monolingual retrieval tasks for CLEF 2001. Our multilingual experiments, the main focus of this year’s work, combine multiple approaches to cross-language retrieval: machine translation, similarity thesauri, and machine-readable dictionaries. We experimented with both query translation and document translation. The monolingual experiments focused on the use of two fundamentally different stemming components: a stemmer based on commercial considerations, and a linguistically motivated stemmer.
