Information retrieval strategy based on education resource grid
基于教育资源网格的信息检索策略*

Based on the research of education resource grid,this paper proposed a logic education resource grid model. Through analyzing the process of information retrieval in education resource grid,presented an information retrieval strategy based on routing label in order to reduce redundancy information and save network bandwidth. The result of the experiments shows that this strategy can effectively reduce the communication cost in education resource grid.
