Asymmetry, Zero Morphology and Tractability
Anna Maria Di Sciullo, Sandiway Fong · Waseda University Repository (Waseda University) · 2001
We present a theory of grammar based on asymmetrical relations, the Strict Asym- metry Theory, and we provide evidence form Indo-European and non Indo-European languages to show that argument structure restrictions on morphological composition follow in a principled way from the theory.We describe and implement a bottom-up parser for morphological selection in the Strict Asymmetry framework.Core lexical properties including argument structure and derivational affix selection are encoded in a uniform mechanism.We consider the computational implications of three different implementations.In particular, we examine the effect on bottom-up parsing from varying the Specifier-Head-Complement order.We provide computational motivation for the logical separation of overt and covert affixation.
