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.

Key words: Information resources organization, Integration of information resources, Information discovery system
