| 摘 要： | 提出一种基于同义词词林的句子语义相似度方法,借助同义词词林来计算句子的词形相似度,使用向量距离法得到句子间的词序相似度。同时,对句子进行语义依存句法分析。通过对词形、词序、语义依存相似度加权结合获得句子之间的最终相似度。将该方法应用于常问问题问答系统(Frequency Asked Questions,FAQ)的问句匹配。实验结果表明,该方法在问句匹配上相比传统方法具有更高的准确率。

| Abstract: | This paper proposed a method of sentence semantic similarity based on TongYiCi CiLin,which used TongYiCi CiLin to calculate the morphological similarity of sentences.The similarity of word order between sentences was obtained by using vector distance method.Meanwhile,the sentences were parsed with semantic dependency.The final similarity between sentences was obtained by weighting the similarity of morphological,word order and semantic dependencies.The proposed method was applied to the question matching of Frequency Asked Questions.Experimental results show that this method has higher accuracy in question matching than traditional methods. |
