基于Ontology的语义检索研究

Research on Semantic Retrieval Based on Ontology

本文从语义检索和概念空间的内涵入手,分析了现有的两种概念空间形式,重点分析了基于Ontology的概念空间的构建方法、描述语言及其编辑工具Protégé.在此基础上,分析了基于Ontology的语义检索系统的构建步骤及其关键技术.最后利用Protégé实现了简单的语义检索.

After an introductive explanation of the connotation of semantic retrieval and concept space, two forms of existing concept space are analyzed. The building method, the description language and the edit tool Protégé of the concept space based on Ontology are studied particularly. Based on these, the steps and the key technologies of semantic retrieval system based on Ontology are analyzed. At last, the simple semantic retrieval is realized using Protege.
