摘要： 针对目前超结点网络研究中的不足，该文基于语义网和小世界理论提出了一种对等网搜索模型——SemanticP2P。模型中结点依据小世界理论在物理上形成自然的区域自治系统(AAS)，各AAS依据幂规律选取各域内的超结点，超结点再根据语义关系形成多个超结点语义网(SSN)，从而形成一个层次化的超结点叠加网络模型，并对其中结点的组织、SSN的构造、搜索机制等进行了阐述，最后通过实验的验证，证明了模型的合理性与有效性。

Abstract: To improve the insufficiency of super-peer overlay network, SemanticP2P, a searching model based on semantic network and the small-world theory is put forward. The peers in model are organized in natural area autonomy system(AAS) based on the small-world theory; Super-peers are selected in each AAS based on power law; and super-peers come into being many super-peer semantic networks(SSN). Thus a hierarchical super-peer overlay network is formed. The organization of peers, the constructing of SSN and the scheme of searching are expatiated too. At last the rationality and validity of model are proved by academic analysis and experimental validate.
