网络上分布着大量异构系统,如何通过网络为信息用户提供信息资源的有效访问,提高检索效率是数字图书馆建设的一个重要指标。以传统数字图书馆系统面临的问题为基础,探讨语义Web对数字图书馆的支持,在整合社会网络和以语义标注的多媒体资源的基础上,构建一种基于语义Web的数字图书馆模型。本体的引入可以增强语义,分面检索的应用则加强了模型系统的检索效率。仿真实验表明模型是有效的。
There are a large number of heterogeneous systems distributed on the network. How to provide information users with effective access to information resources through the Internet and improve the retrieval efficiency is an important index for digital library construction. Based on the problems faced by the traditional digital library system, this paper discusses the support of the Semantic Web for digital libraries and builds a digital library model based on the Semantic Web based on the integration of social networks and multimedia resources marked with semantics. The introduction of ontology can enhance the semantics, and the application of faceted retrieval enhances the retrieval efficiency of the model system. Simulation results show that the model is effective.
