Abstract
QRISTAL [9] is a question answering system making intensive use of natural language processing both for indexing documents and extracting answers. It ranked first in the EQueR evaluation campaign (Evalda, Technolangue [3]) and in CLEF 2005 for monolingual task (French-French) and multilingual task (English-French and Portuguese-French). This article describes the improvements of the system since last year. Then, it presents our benchmarked results for the CLEF 2006 campaign and a critical description of the system. Since Synapse Développement is participating to Quaero project, QRISTAL is most likely to be integrated in a mass market search engine in the forthcoming years.
