数字图书馆是海量、分布、异构、集成的信息资源体系与信息服务体系,网络信息资源是数字图书馆的重要组成部分。文章基于网络信息资源分布的幂规律与网络信息交流的小世界理论,设计了数字图书馆资源自治系统(RAS),以RAS为核心探讨了数字图书馆的网络信息资源发现与服务的概念框架,并详细讨论了概念框架的运行机制。
Digital library is a massive, distributed, heterogeneous and integrated information resource system and information service system. Network information resources are an important part of digital library. Based on the power law of network information resource distribution and the small world theory of network information exchange, this paper designs a digital library resource autonomous system (RAS), discusses the conceptual framework of digital library network information resource discovery and service centering on RAS, And discussed in detail the operating mechanism of the conceptual framework.
