Recognition of hierarchy and semantic relations of compound sentence made up of one mark and three clauses faced to Chinese information processing

WU Feng-wen(College of Liberal Arts,Xinyang Normal University,Xinyang 464000,China)  
It is significant for parsing analysis in computational linguistics and information engineering in compound sentences to recognize hierarchy and semantic relations of compound sentence.In order to solve the problem that marks appeared in compound sentence are not sufficient to identify hierarchy and semantic relations among clauses,the formal syntax and semantic knowledge of compound sentences needs fully exploring,and the knowledge can be available to understand by computers.This paper discusses how subject's consistency and predicate's semantic correlation affect clause semantic association,deeply analyzes four kinds of mark modes which are made of one mark and three clauses,and extract 9 rules which restrict hierarchy and semantic relations of compound sentence.
