通过研究中文问答系统的理论,进而分析当前计算语句相似度的方法,比较各种计算语句相似度方法的适用场合以及它们的优势与不足,对计算语句相似度的方法提出了新建议,并以语句相似为基础建立了一个中文问答系统的模型。这个中文问答系统模型包含了许多常见问题,通过实践证明中文问答系统比主流的VSM方式具有更强的语句相似度匹配功能。
By studying the theory of Chinese question answering system and analyzing the current methods for calculating the similarity of sentences, comparing the applicability of various similarity methods for calculating sentences and their advantages and disadvantages, a new suggestion is put forward for calculating the similarity of sentences. Sentence similarity based on the establishment of a Chinese question answering system model. The Chinese question answering system model contains many common problems, and it has been proved by practice that the Chinese question answering system has stronger sentence similarity matching function than the mainstream VSM method.
