| 摘 要： | 在网络舆论的传播过程中,舆论传播者通过特定话题的引用关系形成了一个网络.本文通过对我国某网络论坛数据进行分析处理,发现该网络的度分布为幂律分布,有明显的无标度特征.除增长和优先连接外,网络舆论传播的媒介的演化还包括兴趣衰减、初始吸引度和边的添加等事件,据此建立了网络舆论传播的媒介度衰减模型并进行了仿真.仿真结果表明,模型的统计特性与实际数据吻合,对网络舆论传播的研究有一定的实际意义.

| Abstract: | In the process of network based opinion formation,owners of opinions form a huge network based on the reference of special topics which is called the media of network based opinion formation.Based on analysis of data from a domestic Internet forum,it is found that the degree distribution of this network is a power law distribution and has the scale-free characteristic.Besides the addition of nodes and preference of links,the evolving of network based opinion formation networks have events like interest decay,initial attractive degree and addition of edges.Proposed a network based opinion formation media evolving model consequently.The result of simulation fits the statistical data well,so the opinion formation model can be used as a foundational one. |
