| 摘 要： | 基于Ontology的语义检索是建立在语义网的基础上的检索技术。与传统的检索技术相比,它能提高检索的精度和覆盖率,减少了不相关的返回结果。文章首先介绍了语义网和Ontology的基本概念及如何创建基于Ontology的语义网,然后详细讨论了基于Ontology的语义检索的基本思想,基本结构及语言,最后描述了基于Ontology语义检索的应用系统,并分析了基于Ontology语义检索技术下一步的发展方向。

| Abstract: | This paper gives an overview of the main ideas and the technology of Semantic Searching based on Ontology.Semantic search based on Ontology is search strategy for the semantic web.The semantic search results in improvement in the precision and the recall of search application on the web.lt decreases the irrelevant searching return compared with the tradition searching.This paper first summarizes some conceptions of the semantic web and how to establish semantic web based on Ontology,then introduces the basic principle of semantic search based on Ontology, the frame of the semantic search,and the language in use in detail.At last,some applications of the semantic search are presented and the aspects of the semantic search are exposed. |
