HPSG and Categorial Grammar

This chapter aims to offer an up-to-date comparison of HPSG and Categorial Grammar (CG). Since the CG research itself consists of two major types of approaches with overlapping but distinct goals and research strategies, I start by giving an overview of these two variants of CG. This is followed by a comparison of HPSG and CG at a broad level, in terms of the general architecture of the theory, and then, by a more focused comparison of specific linguistic analyses of some selected phenomena. The chapter ends by briefly touching on issues related to computational implementation and human sentence processing. Throughout the discussion, I attempt to highlight both the similarities and differences between HPSG and CG research, in the hope of stimulating further research in the two research communities on their respective open questions, and so that the two communities can continue to learn from each other.
