【摘要】 本文以发现系统的信息资源聚合与组织功能为例,对信息资源聚合和组织方法进行了分析。本文指出,基于元数据预索引和元数据仓储的发现系统,主要是通过对不同来源的元数据记录进行收割、转换,来实现信息资源的组织和聚合。而真正的资源"发现",是要实现基于知识的数据关联,挖掘资源之间隐含的关系。因此,需要在元数据仓储的基础之上进一步构建一个资源组织和深度聚合的整体框架体系,从语义层面上实现信息资源的组织和聚合。更多还原

【Abstract】 By discussing the study of the main information discovery systems in China, this paper analyses the methods of integration and organization of information resources. Based on metadata pre-index and metadata repository, information discovery systems realize the integration and organization of information resources by harvesting and transforming metadata records from various resources. The real information resources "discovery" is to realize the data relationship based on knowledge and through mining the internal relationship between information resources. Therefore, it needs to build up a framework of information resource organization and deep aggregation based on metadata repository, and realize the organization and aggregation of information resources from the semantic level.更多还原
