The Computing Method of Semantic Relevancy of Clauses in Chinese Compound Sentence

The automatic recognition of hierarchy and relationship of Chinese compound sentence is a difficulty in Chinese information processing, and it is even more difficult in two points, one is the hierarchy ascription of non-marked clauses, the other is the confirmation of relevancy of clauses in some causal and coordination marked compound sentences. It uses semantic relevancy theory to solve these problems in this paper. The discussion focuses on three parts: sum up the semantic features which indicate the semantic relevancy between clauses from the syntactic and semantic aspects; confirm the analysis order of features according to the restriction law among features and the statistic result of the occurrence of clauses´ features in corpus; discuss the computing method of the semantic relevancy degree between clauses, and then confirm the hierarchy ascription of clauses according to semantic relevancy degree.
