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.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.
