摘　　要：针对数字图书馆中存在的信息资源的异构性及不同信息系统的互操作问题,探索将语义Web服务应用在数字图书馆网格应用系统中的方法。如何根据用户输入识别用户需求,并为其提供最为准确的服务,以提高信息检索的效率和准确性是文章的主要研究内容。通过计算机模型和理论模型的建立和设计,探求语义网格环境下的数字图书馆信息服务机制和理论模型。设计并实现了语义调度和硬件资源监控调度两种调度方式和算法。As for the isomerism of information resources and the interoperability of different information systems existing in digital libraries, this paper explores the method of applying semantic Web service in the grid application system of digital libraries. How to identify user needs according to their input and provide the most accurate service for them so as to improve the efficiency and accuracy of information retrieval is the main research content of this paper. Based on the construction and design of the computer model and theoretical model, the paper probes into the mechanism and theoretical model of information service in digital libraries in the semantic Web environment. The paper designs and implements 2 dispatch methods and algorithms, namely, semantic dispatch and hardware resources monitoring and dispatching.
