基于语义关联技术的信息检索策略

Information retrieval based on framework of semantic association

为提高在海量数据中的信息检索效率,分析了元数据目录服务技术的现状及其不足,通过引入语义关联技术,将语义关联的信息检索技术与网格信息服务技术有效结合,提出了一种改进的能有效提高检索效率的检索框架,并结合实例进行了描述。实验结果表明,该优化的语义关联查询方法是有效、可行的,能有效提高海量数据中信息检索的查准率和查全率。

In order to improve the efficiency of information retrieval in the mass data,analysis of the status and shortcomings of the MDS（metadata directory service）,by introducing the semantic association,combined with the technology of semantic association and grid information service,an improved retrieval framework is proposed,and it cominded with examples are described.The results show that this semantic association query optimization method is effective and feasible,it improve information retrieval in huge data precision and recall.
