Application Of Knowledge Service Grid In Network Education

With the development of network technology, the demand for information on net is increasing rapidly. Grid's development in the future aims at enabling people to share resources to highly degree, providing calculation on a large scale and easy operation technic with its emphasis on automation, cooperation in distributed system and virtual organization. Grid has formed Open Grid Services Architecture (OGSA) after combining Web Service technic. OGSA views Grid Service as sets can be enlarged, and all in OGSA is for service. The arrival of OGSA makes application of Grid go beyond the application field of Grid Computing, achieves great development in Knowledge Service, Intelligence Agent, cooperation in distributed system, which enable individual and organization mainly depended on aquiring information from Network to take in useful information from sbustancial information easily, without concerning about source of information and redundancy.This paper elaborates the concept of Grid basic content of Grid Service, describes OGSA systematic structure and running theory, and then proceeds to put forward Kowledge Service Sysmatic Structure based on Grid Service. It explores the application of this sysmatic structure to Network Education to really realize the freedom, intelligence, pracicality and humanity of knowledge service.This paper is a significant attempt at research work of OGSA systematic structure. This research tests and verifies the advatage of OGSA systematic structure in realizing sharing resources and cooperation under virtual environment, and eliminating isolation of information and resources. Although application of OGSA systematic structure is not ready, and the exploitation and distibution of Grid Service are waiting to be perfect, OGSA systematic structure will develop swiftly and violently with the development of related technic and application.
