信息网格中基于本体的信息共享全局视图构建方法研究

信息共享对于增强信息网格单元的协作能力和快速反应能力起着至关重要的作用．从解决信息网格语义异构问题出发，为实现网格信息共享，提出了一种基于本体的信息网格全局视图构建方法．该方法主要由两部分核心内容组成：全局本体的生成和基于全局本体的全局视图构建．首先深入研究了信息网格全局本体的生成；基于全局本体透彻分析了如何构建信息共享全局视图；结合具体实例详细说明了所提出信息网格全局视图构建方法的工作流程与应用．对于相关工作进行了分析比较，最后给出了结论和下一步工作．

Ontology Based Global View Construction for Information Sharing in Information Grid

In information grid information sharing is very important for the grid units to cooperate with each other and to react to the ever changing environment From the point of view of resolving semantic heterogeneity, an ontology based global view construction approach is proposed to achieve information sharing in information grid In this approach, the local ontologies are merged into the global ontology by means of similarity relations As the global ontology, the global view is constructed through integrating the local information source schemas An example of constructing the global views in the E government information grid is presented to illustrate the approach Finally, the related work is introduced, and the conclusion and future work are given
