Dependence language model for information retrieval
This document describes the CLIPS experiments in the CLEF 2005 campaign. We used a surface-syntactic parser in order to extract new indexing terms. These terms are considered syntactic dependencies. Our goal was to evaluate their relevance for an information retrieval task. We used them in different forms in different information retrieval models, in particular in a language model. For the bilingual task, we tried two simple tests of Spanish and German to French retrieval; for the translation we used a lemmatizer and a dictionary.
