本文基于实测数据抽象出用户网络与资源网络,探讨了对等网络中用户、资源及其内部的相互作用关系,发掘并分析了其内在的网络统计特征.分析结果表明,用户节点度值及权值呈分段分布,体现了其各异的活跃性;网络资源的流行度差异明显,度值和权值近似呈幂律分布.用户网络与资源网络存在分簇结构,少数簇中含大量节点,多数簇所含节点数量较少.用户网络中,同簇内的用户有着相似的兴趣趋向,不同簇用户间兴趣趋向存在着差异,资源网络各簇中不同类别的资源间呈现出明显的关联性.
This paper abstracts the user network and the resource network based on the measured data, explores the interaction among users, resources and their internal networks in the peer-to-peer network and explores and analyzes the inherent network statistical characteristics.The results show that user node degree and right The distribution of values is in a piecewise distribution, which shows its different activities. The popularity of network resources is obviously different, and the degrees and weights are approximately power-law distribution. There exists cluster structure in user network and resource network, , Most of the clusters contain a small number of nodes.Users in the same network have similar interests and tendencies of interest among different clusters, and there is a clear correlation between different types of resources in each cluster Sex.
