Syntactic Function-Based Chinese Lexical Categories and Category Grammar Parsing

By merging syntactic categories of word classes, lexical categories were obtained. By demonstrating combination and type raising rules respectively from curried and uncurried perspectives, a category combination algorithm was presented, in which application, composition and type raising rules were sequentially examined, and the first available rule was selected. A Chinese CCG parser was developed, including Chinese word segmentation, category annotation, and syntactic parsing, which could obtain all parsing trees for given category sequence, but only determinatively chose one to print. Experiments show the parser can correctly perform categorial derivations, and lexical categories determined by syntactic function are reasonable and acceptable.
