Abstract


This paper combines the Semantic Web technology with grid technology to solve the interoperability of distributed heterogeneous systems in the field of digital libraries. Proposed semantic grid technology to build a digital library of virtual organization conceived in order to achieve a distributed heterogeneous systems, remote collaboration, massive distributed storage of information resources, and maximize the sharing of digital library resources, reference grid technology in workflow Thought organized grid Web / grid services coordination complete grid users demand, while using the Semantic Web ontology technology to describe the metadata of services and resources to enhance the interoperability of services and resources, and The design service lookup Framework to automatically find the combination of call and monitoring of these services and resources. The text that will be described in detail based the grid OWL-S/UDDI service lookup framework, it is as the agent in the middle of the service providers and service consumers, and mapping between service consumers and providers, according to the request to provide service consumers most matching service. Improved service matching algorithm, the classification of four screening service from the context, service features, service quality and service. Finally, the service to find a framework for application development and design of digital library infrastructure model Hbutigrid. In order to achieve Hbutigrid, first article Globus engineering technology to build a grid on the Linux server platform, Introduce tools automatically generate and publish Web / grid services, and the use of the grid cluster monitoring tool Ganglia monitoring grid services and resources host work status. At the same time, in order to provide a semantic environment to framework of OWL-S/UDDI service Find text metadata OWL ontology language model to design the domain ontology using OWL-S web service description model based on OWL language to extend the WSDL service description document information to facilitate service to retrieve, and finally use the Jena tool ontology semantic reasoning to obtain semantic information services. Finally, Find framework based OWL-S/UDDI service ontology-based digital library search services. Order to improve the accuracy of its resources to retrieve the CAS segmentation tools ICTCLAS3.0 user input cut word to get a meaningful word, \classification, will be on the grid digital library retrieval service disciplines of their resources to provide classification, in order to further improve the accuracy of the framework of the service matching.
