National audienceIn this paper, we describe how we converted the lexicon-grammar tables into an NLP format, that of the Lefff lexicon, which allowed us to integrate it into the FRMG parser. We decribe the linguistic basis of this conversion process, and the resulting lexicon. We validate the resulting lexicon by evaluating the FRMG parser on the EASy reference corpus depending on the set of verbal entries it relies on, namely those of the Lefff or those of the converted lexicon-grammar verb tables
