| 摘 要： | 问题理解是问答系统中的一个关键步骤.问题理解的过程包括疑问词分类、问句分词及词性标注、疑问句句型识别、问题分类及问题中心的识别等.提出了对疑问句句型的识别方法,即通过对疑问句的短语句法树的分析,得到疑问句的句型结构,通过计算句型结构与句型模式之间的相似度来识别句子的句型.结合疑问句的语法分析,通过识别疑问句的句型实现了问题理解.实验结果表明,该方法提高了问题理解的准确度.

| Abstract: | Question analysis is the primary task of question answering system.The process of the question analysis in this paper was described as follow:identifies the interrogative phrase class,parses words,identifies the question's sentence type,identifies the question class.A method of Sentence Type Recognition(STR) was put forward as:the sentence type structure of a question results from analyzing the phase syntactic tree for the sentence,with computing the similarity between the sentence type structure and the se... |
