基于代理的层次化信息网格模型

A Hierarchical Information Grid Model Based on Agent

为了实现信息网格中的信息共享,将网格中的信息以元数据的形式表示,在网格中设置元数据服务代理,对信息进行语义分析和数据融合,生成元数据目录,最后通过基于兴趣的定购发布机制实现信息网格中信息共享,提高系统的可靠性、可用性及访问效率。

To share information in the grid, the information is represented in the form of metadata. And data service agents are established to make semantic analysis and data fusion to the information,through which metadata index is obtained. Finally,information sharing can be realized by using the interest- based ordering and publishing mechanism, and the reliability, availability and access efficiency of the system is also improved.
