Abstract
Chinese sentence is parsed with PSG (Phrase Structure Grammar) rules in syntactic analysis. Grammatical rules based on PSG are not consistent so that ambiguity is a big problem. In this paper, we propose a new kind of grammar SSG (Sentence Structure Grammar), which describes all component and centers on predicative verb or adjective. We build a Chinese grammatical rule system based on SSG and mount it on extended chart parser Schart. The result of experiment showed that the syntactic analysis based on SSG that only uses the information of part of speech and grammatical rules is very consistent and very effective to reduce syntactic ambiguity, and it can gain a higher precision than syntactic analysis based on PCFG (Probabilistic Context Free Grammar).
