  3. At the same time , because general hierarchical is not good on question classification , this paper proposes a new method for chinese question hierarchical classification . this method combines the key class features with the question syntactic features to classify questions . since this method extracts the syntax features and adds syntax information into question classification , at last , the precision of the coarse classes reaches 88 . 25 % and fine classes reaches 73 . 15 % , respectively improves nearly ten percent than the traditional hierarchy classification , proving this method is effective
    本文针对文本分类和问题分类的差别,利用依存分析提取主干和疑问词及其附属成分,并结合主干关联词对,采用支持向量机分类器,此方法大大减少了问题分类的噪音,突出了问题分类的主要特征,并考虑了词与词之间的句法关系,取得了良好效果;同时,针对普通层次分类在问题分类上效果不理想的情况,本文提出了类别主特征结合句法特征的中文问题层次分类新思想,利用句法分析提取分类特征,在问题分类中融入了句法信息,总的准确率达到大类88 . 25 %和小类73 . 15 % ,比传统的层次分类分别提高了10个百分点,证明了此方法的有效性。
