We describe a computational lexicon which encodes verbal syntactic constructions in French. The aim of the project is to encode into a standard formalism the valency lexicon for French initiated in the eighties by M. Salkoff and A. Valli and continued since then. The whole computational lexicon will include about six thousand verbal entries with a list of the arguments of each verb, the restrictions associated with the arguments and examples found in real corpora. Such a lexicon may be a useful resource for the linguistic community as well as for natural language processing applications.
