摘要
智能答疑是现代远程教育中一个重要组成部分,但目前网络答疑系统反馈答案的查出率和准确率较低。文章在分析用户问题与标准问题语句的模糊贴近度的基础上,提出了基于阈值的模糊贴近度算法。通过对系统运行情况的分析,证实了该算法能有效地提高答疑系统的智能处理能力。
Intelligent answering is an important component of modern distance education,however detection rate and accuracy rate of the feedback answers from network answer system are still relatively low at present.This paper analyzes fuzzy proximity of user question sentences and standard question sentences,and then proposes an algorithm of fuzzy proximity based on the threshold value.Through the analysis on the system operation,it is proved that this algorithm can effectively improve intelligence processing ability of the answer system.
