面向信息处理的“一标三句式”复句层次关系判定

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

复句层次关系识别对计算语言学句法分析和复句信息工程意义重大。为解决关系标记显现不充足给复句层次关系识别所带来的困扰,需要充分挖掘可供计算机理解的复句关联的形式化句法语义知识。研究探讨分句主语指称一致性和谓语语义相关性对分句语义关联的影响,并深入分析4种联结模式的"一标三句式"复句的句法语义特点,可总结提取了9条层次关系判定规则,以此为复句层次关系识别奠定基础。

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.
