Koskenniemi’s two-level morphological analysis system can be improved upon by using a PATR-like unification grammar for handling the morphosyntax instead of continuation classes, and by incorporating the notion of negative rule feature into the phonological rule interpreter. The resulting system can be made to do generation and recognition using the same grammars.
