摘要: 以语法功能匹配作为句法分析的基本方法,以100万词清华973树库作为语法功能调查的主要资源,实现了一种基于语法功能匹配的句法分析算法。该算法能有效减少伪歧义,具有良好的分析效率,其分析结果包含了丰富而准确的语法信息。实验表明,短语正确率与召回率在封闭测试和开放测试中分别达到75.17%、73.69%和65.06%、56.55%。

Abstract: Based on the primary method of Grammar Function Match as the syntactic analysis,this paper realizes a kind of parsing algorithm,which views the TCT 973 as principal resource to survey the grammatical function.This algorithm not only efficiently reduces the fake ambiguities,but also has a favorably analyzed efficiency,which analyzes results including abundant and accurate grammatical information.The experiment indicates that the rate of phrase precision and recall reaches 75.17%,73.69% and 65.06%,56.55% respectively in close test and open test.
