Modélisation et implémentation de phénomènes flexionnels non-canoniques

Abstract : Non-canonical inflection (deponency, heteroclisis. . . ) is extensively studied in the- oretical morphology. However, these studies often lack practical implementations associated with large-scale lexica. Yet these are precisely the requirements for objective comparative stud- ies on the complexity of morphological descriptions. We show how parsli, our model of in- flectional morphology, manages to represent many non-canonical phenomena and to formalise them in way allowing for their subsequent implementation. We illustrate it with data about a variety of languages. We expose experiments conducted on the complexity of four compet- ing descriptions of French verbal inflection, which is evaluated using the information-theoretic concept of description length. We show that the new concepts introduced in parsli reduce the complexity of morphological descriptions w.r.t. both traditional or more recent models.
