摘要
针对P2P网络不支持语义查询以及语义Web中知识存储过于集中的问题,本文采用超节点对等网网络的方法,将对等网技术和语义Web技术结合起来,提出了一种新的语义对等网体系结构。结构中节点根据物理位置拓扑的不同形成区域自治系统(AAS),各AAS内节点根据语义相似度形成语义簇(SC),语义簇内选择性能最高的节点作为超节点,超节点再根据语义关系形成超节点语义网(SSW),从而形成一个三层架构的语义对等网体系结构。最后通过实例验证了所提出来的语义对等网体系结构。
Based on the problem that the p2p network does not support semantic query and the centralization of knowledge storage in semantic web,this article adopted the super-class peer-to-peer network method,the combination of p2p technologies and semantic web technologies was covered in this paper as well as a new kind of semantic peer-to-peer web architecture.In the structure of Semantic P2P web,depending on the different physical locations of topology the peer forms Area Autonomy System（AAS）.The nodes in the AAS form a Semantic Cluster（SC）in accordance with the semantic similarity.The nodes with highest property in the SC were selected as Super-Peer（SP）.According to the semantic relations,SP forms the Super-Peer Semantic web（SSW）.Thus a three-layer architecture of semantic p2p web was accomplished.Finally,the architecture of semantic p2p web was verified by an example.
