三网融合区域云数字图书馆跨库检索服务研究

Research on Cross-database Search Service of Regional Cloud Digital Library in Three Nets Fusion Environment

为了促进区域云数字图书馆与三网融合的结合,使区域图书馆扩展信息资源,更好地为读者服务,针对目前区域云数字图书馆在三网融合环境下跨库检索的困难,对该环境下的跨库检索服务进行了研究。首先研究来自于三网的信息资源、异构终端并进一步研究跨库检索服务的需求,随后提出该环境下跨库检索服务的模型,再根据跨库检索服务的模型提出相对应的跨库检索服务的流程,最后对信息资源的管理与定制、信息资源的权限、信息资源的推送、跨媒体检索进行了研究。

Research the cross-database search service of the regional cloud digital library in three nets fusion environment, to promote the combination of the regional cloud digital library and three nets fusion, making regional library expands information resources and serves readers, solving the retrieval problems. Firstly, research the information resources from three net and abnormal terminator, and further study the demand of cross-database retrieval service. Secondly, propose the cross-database search model, according to which the corresponding process of cross-database search service is put forward. Finally, research the management, the custom made, the authority and the delivery for the information resources and cross-media retrieval.
