基于问题关键词匹配度的相似度计算

摘要

Question answering is an indispensable link in the teaching, the traditional face-to-face question answering waste of time and energy.So develop effective, accurate, intelligent automatic question answering system is necessary. The accuracy of the system to return to the answer in a certain degree depends on the degree of similarity matching problem. This paper introduces resemble degree account in the intelligent question answering system, then putting forward a new kind of resemble degree ac⁃count basing traditional resemble degree account, which Resemble degree account of basing match degree of key word and ques⁃tion. And arithmetic which that ideal is implemented in the system is provided.%　　答疑是教学中不可或缺的环节，传统面对面的答疑浪费时间和精力，因而开发高效、准确、智能化的自动答疑系统是必要的。系统返回答案的准确性在一定程度取决于问题匹配的相似度。该文介绍了智能答疑系统中传统的相似度计算，然后在传统的相似度计算的基础上提出了一种新的相似度计算方法——基于问题关键词匹配度的相似度计算，同时给出了该思想在系统中的实现算法。
