This paper discusses the difficulties in Chinese deep parsing, by comparing the accuracy of a Chinese HPSG parser to the accuracy of an English HPSG parser and the commonly used Chinese syntactic parsers. Analysis reveals that deep parsing for Chinese is more chal-lenging than for English, due to the shortage of syntactic constraints of Chinese verbs, the widespread pro-drop, and the large distribu-tion of ambiguous constructions. Moreover, the inherent ambiguities caused by verbal co-ordination and relative clauses make semantic analysis of Chinese more difficult than the syntactic analysis of Chinese. 1
