虚拟社区网络的演化过程研究

模拟了虚拟社区网络的演化过程并研究其拓扑结构.发现虚拟社区网络在演化过程中，节点的加入、边的加入、网络中度分布、节点的度与其加入网络时间的关系、平均度随时间的变化等方面与传统的无标度网络有所不符.根据国内某论坛的实际网络数据统计与分析，提出了虚拟社区网络的演化机理——虚拟社区网络构造算法.仿真结果表明，模拟以互联网论坛为代表的虚拟社区网络时，该模型能够得到与真实网络相符的特性. 关键词： 复杂网络 虚拟社区 无标度网络

Research on the evolution process of virtual community networks

We investigate and simulate the evolution process and topological features of the virtual community networks.We founded that the joint of nodes, joint of edges, networks' degree distribution, average degree and the correlation between the node's degree and its time in the network are different from the scale_free network model.With statistics and analysis of some of the characteristics of an actual Internet forum, we propose a new network evolution algorithm, namely the virtual community network construction algorithm.The simulation results show that the networks generated from our algorithm has the same characteristics as the real virtual community networks.
