摘要
通过对教育资源网格的研究,提出了逻辑层次式模型,并对资源检索过程进行分析;然后从过滤冗余信息的角度出发,提出了一种基于路由标注的信息检索策略,有效减少冗余信息的产生,节省网络带宽。最后通过理论分析和模拟实验表明,该策略可以有效地减少教育资源网格中信息检索的通信开销。
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.
