We apply Combinatory Categorial Grammar to wide-coverage parsing in Chinese with the new Chinese CCGbank, bringing a formalism capable of transparently recovering non-local dependencies to a language in which they are particularly frequent. We train two state-of-the-art English ??? parsers: the parser of Petrov and Klein (P&K), and the Clark and Curran (C&C) parser, uncov- ering a surprising performance gap between them not observed in English ? 72.73 (P&K) and 67.09 (C&C) F -score on ???? 6. We explore the challenges of Chinese ??? parsing through three novel ideas: develop- ing corpus variants rather than treating the cor- pus as fixed; controlling noun/verb and other ??? ambiguities; and quantifying the impact of constructions like pro-drop.
