【摘要】 智能问答系统是在搜索引擎的基础上融合了自然语言知识和应用的人工智能产品,相比较传统的依靠关键字匹配的搜索引擎,能够更好地满足用户的查询需求。针对现有的英语智能问答系统中知识呈现的单一化以及系统查询效率低等现状,采用基于距离的相似度算法,设计并实现了基于相似度算法的英语智能问答系统。实验结果表明该系统能够较为准确地回答小学生的英语问题,对远程教育中小学英语智能问答系统的构建起到参考和借鉴的作用。更多还原

【Abstract】 Compared with the traditional search engine which is rely on the keyword matching,intelligent questionanswering system integrates with the knowledge and application of natural language on the basis of the search engine,so as to satisfy users’ information retrieval requirement. Aiming at current simplified knowledge and inefficient system query of English intelligent question answering system,the research adopts the similarity algorithm based on distance,designing and implementing English intelligent question answering system based on similarity algorithm. The results show that the system can answer students’ questions accurately. The conclusion of this research can be used as references to the construction of English intelligent question answering system in distance education.更多还原
