摘　　要：答疑系统是远程教育系统的重要组成部分,针对传统答疑系统功能相对简单而且无法得到理想的答案等特点,提出一种基于领域本体智能答疑系统的设计。文章首先提出智能答疑系统的模型,并进行领域本体和问句语料库的构建研究,同时利用分词处理和关键词扩展技术进行问句查询的扩展,最后通过语句相似度的匹配方法,提升系统查询的准确率。Answering system is an important part of distance education system,for the relatively simple functions and no ideal answers of traditional answering system,the design of the intelligent question answering system based on domain ontology is put forward.Firstly,the article put forward the mode of the intelligent question answering system,and researched the building of the domain ontology and question library,and extended the questions based on word processing and keyword expansion.Finally,it improve the accuracy of the system check through the sentence similarity.
