Problématique des chercheurs en traitement automatique des langues des signes

French Sign Language (LSF) automatic processing research has to deal with uncomplete corpora of a language which is not yet fully described and has no written form. So, the researchers must carry out reductions at every representational level, constrain the conditions of acquisition of LSF discourses and limit the field of their applications. It is important that they should explain and justify those reductions and know what such reductions imply. In this paper, we will present some of the characteristics of LSF organisation and evolution as well as the different approaches that allow to reduce the complexity of the treatments while preserving most of LSF peculiarity. Mots-clés : iconicisation, création lexicale, analyse d’images, génération, contraintes.
