This paper describes an original approach which aims at building a reference semantic lexicon for French. Its main characteristic is that of relying on morphological properties. The method combines morphological analysis results from large-scale lexical resources (i.e. word lists from the ‘Trésor de la langue Française informatisé' (TLFi)) with already tested acquisition methodologies on lexical information. The representation format, within the Generative Lexicon framework, has been chosen for its expressiveness and conciseness features. This approach allows us to consider building a reference lexicon for French, which is fundamentally homogeneous and also has large coverage. A feasibility study of the described method provides a projection of expected results, from both quantitative and qualitative points of view.
