摘要： 句子相似度算法是基于常问问题集的问答系统(FAQ)的关键。针对汉语中一词多义现象，提出一种改进的基于知网的词义消歧算法，确定词语在不同上下文环境的义项号，利用知网系统及义项号，使用改进的相似度计算方法进行相似度计算模块设计。结合实际应用，实现一个实际的FAQ系统。实验证明，改进的词义消歧方法提高了消歧的精度和速度。而词义消歧的引入提高了问答系统的精度和速度。

Abstract: Sentences similarity arithmetic is the key of Frequency Asked Question(FAQ). There are many muti-sense words in Chinese. This paper proposes a new arithmetic of word sense distinguish based on HowNet, uses the advanced method to the sentences similarity and realizes a real FAQ system. Word sense distinguish uses the proposed method to do the word sense distinguish. The sentences similarity is got with HowNet, and a real FAQ system is realized. Experimental results show that the proposed method can effectively increase the accuracy of the FAQ system.
