Abstract

This document presents the experiments we performed for our CLEF 2004 participation. We have tested the use of surface-syntactic parsing to extract indexing terms. We have also studied the Deviation From Randomness weighting. For the bilingual part, we have experimented reinforcement query weighting using an association thesaurus.
