In this paper, we describe the integration of Lexicon-Grammar tables for French verbs in the large-coverage FRMG parser and the evaluation of the resulting parser. This integration required a conversion step so as to extract the syntactic information encoded in Lexicon-Grammar tables and represent it in the NLP lexical formalism used by FRMG, i.e., the Alexina framework (that of the Lefff lexicon, on which the standard version of FRMG relies). We describe the linguistic basis of this conversion process, and the resulting lexicon. We compare the results of the FRMG parser on the EASy reference corpus depending on whether it relies on the verb entries of the Lefff or those of the converted Lexicon-Grammar verb tables.
