【摘要】 阐述了目前网络上的搜索引擎主要是基于关键词索引查询技术而设计的,这种技术的搜索范围很大,但由于关键词难于表达丰富的概念和用户信息需求中的丰富语义,导致查准率很低。以语义W eb和基于语义的网络信息检索技术为理论根据,从克服目前信息组织和信息检索的矛盾出发,用XML/RDF作为语义描述、组织、存储、查询的工具,试图在未来搜索引擎发展方面做一些尝试性的研究,提出了一个基于自然语言查询的搜索引擎模型。更多还原

【Abstract】 At present search engines on the net are designed mainly based on index search technology.The search range of this technology could be very wide,but it is difficult for keywords to express rich concepts and the abundant semantics in customers’ information needs,the search precision is very low.This paper is theoretically,based on Semantic Web and network information retrieval,laying foundation of semantics.For overcoming the contradiction between information organization and information retrieval,using XML/RDF as the tool of semantic description,organization,storage and search,this paper brings forward a search engine model based on natural language search and tries to do some research referring to the future search engine.更多还原
