基于本体的对等网语义检索系统

Ontology-based Semantic Information Retrieval Systems in P2P Network

针对目前采用关键字匹配实现信息检索的不足,借鉴利用本体进行信息集成的方法提出非结构化对等网的语义检索系统架构,描述各模块的功能,并深入讨论实现语义检索需解决的关键技术——资源描述与提问处理、资源搜索和本体映射等。

In this paper, considering the limitation of keywords - based information retrieval, a framework of Ontology - based semantic information retrieval systems is put forward according to the hybrid Ontology - based integration approaches, and the functions of every module are described. In addition, some key issues are discussed, including query and resource processing, resource searching, and Ontology mapping.
