Abstract: Semantics distributed storage for better resource sharing is a focus in the study of semantic grid. This paper analyzes variety of P2P structures, and applies Super-P2P structure to semantic grid. Semantic grid based on Super-P2P is presented to address problems of semantics centralized storage in semantic grid, and resource discovery of Super-P2P semantic grid and knowledge services based on Super-P2P semantic grid are reported. Application case study demonstrates that the knowledge sharing model based on Super-P2P semantic grid can share resources better, and provide high-quality, high-reliability knowledge services.

摘要： 在语义网格的研究中，如何超越集中式的语义存储，实现更高程度的资源共享，是目前语义网格的研究热点之一。在分析多种P2P结构的基础上，该文Super-P2P结构应用于语义网格，以解决语义网格的语义集中式存储问题。研究了Super-P2P语义网格的资源发现机制以及基于其的知识服务。应用案例分析证明，基于Super-P2P语义网格的知识共享模型可以实现更高程度的资源共享，提供高质量、高可靠性的知识服务。
