Lexically Specified Derivational Control in Combinatory Categorial Grammar

Abstract

This dissertation elaborates several refinements to the Combinatory Categorial Grammar (CCG) framework which are motivated by phenomena in parametrically diverse languages such as English, Dutch, Tagalog, Toba Batak and Turkish. I present Multi-Modal Combinatory Categorial Grammar, a formulation of CCG which incorporates devices and category constructors from related categorical frameworks and demonstrate the effectiveness of these modifications both for providing parsimonious linguistic analyses and for improving the representation of the lexicon and computational processing. Altogether, this dissertation provides many formal, linguistic, and computational justifications for the central thesis that this dissertation puts forth- that an explanatory theory of natural language grammar can be based on a categorial grammar formalism which allows cross-linguistic variation only in the lexicon and has computationally attractive properties.
