基于语句相似度计算的智能答疑系统机理研究
Research on Mechanism of Intelligent Question Answering System Based on Sentence Similarity Computation
摘要
Abstract
In order to solve the problem of poor real-time performance,low accuracy and low efficiency of the existing question answer-ing methods in the process of online learning with the Internet,we present an intelligent question answering scheme based on the similarity calculation of sentences.First,we analyze the existing methods of question answering and their defects,then elaborate the work flow,the overall structure and the related database structure of the intelligent answering system.The common problem database is added for the problem of low retrieval efficiency of the original question answering method,and the word matching method based on the string matc-hing is introduced to complete the separation of questions raised by learners.Finally,the similarity calculation method based on the word information is used to calculate the statement similarity of which the result is given to the learner,so as to improve the accuracy,efficiency and real-time performance of the system and meet the needs of learners.Experiments show that the scheme has higher accuracy and effi-ciency than original answering scheme.关键词
