摘要
依存句法分析是对自然语言进行自动分析构建句子对应的依存树的一种方法,是自然语言处理重要的一部分,但目前依存句法分析的准确率并不高。介绍了依存句法结构并对依存句法的分析方法进行了总结与综述,介绍了基于规则的依存句法、基于统计的依存句法和规则与统计相结合的依存句法的分析方法。最后,分析了汉语依存句法分析的困难和优势。
Dependency parsing is a method of automatic analysis of natural language building sentence corresponding de- pendency tree. It is an important part of natural language processing, but the current dependency parsing accuracy rate is not high. This article describes the dependency syntactic structure and reviewes the syntactic dependency analysis method. After this, the paper introduces rule - based dependency syntax, dependency syntax based on statistical and rules combined with the statistical dependencies syntactic.
