BBS用户回复网络的演化模型研究

结合复杂网络理论,首先利用获取的真实BBS论坛数据信息构建有向BBS用户回复网络,并分析日增节点数、日增边数、新用户发表原帖数、新用户获得回帖数、节点择优选择概率等的演化规律.其次,提出新的网络构造模型,并进行数据仿真.仿真结果表明,仿真网络的网络结构熵、度分布的演化规律与真实网络基本吻合,在一定程度上能够证明研究方法的正确性,也能解释真实BBS网络的演化规律,具有一定的现实意义.

Evolving Model of Reply Network on BBS

With the theories of complex network, reply network was built with the data downloaded from real BBS and then studied the evolution of network topological structure with time, including the number of new nodes and new arcs, initial articles posted by new nodes, reply articles pointed to new nodes and the preference of nodes. Then, a network construction model was proposed based on the previous work. Simulation results showed that its regular of degree distribution and network structure entropy was mostly the same as that of the real network on BBS, which can prove the correctness of research method and explain the evolution of real BBS practically, and is consequently of strong practical significance.
