摘要
通过在无标度BA(Barabási-Albert)网络上设计个体的局部相互作用规则,讨论对立舆论在BA网络中的传播规律.将对立舆论传播过程分为自由传播和竞争传播两个阶段,并设置自由传播阈值m1和竞争传播阈值m2,传播深度h.实验结果表明:随着m1,m2值的变化及传播深度h的变化,对立舆论在网络中呈现出不同的分布情况,从而导致舆论传播的最终结果不同.
In this paper,rules of individuals local interaction were designed in the scale-free BA（Barabási-Albert）network,and propagation of opposing public opinion was discussed in the BA network.Opposing public opinion′s propagation process was divided into two stages of free dissemination and competition propagation,and threshold value of free dissemination m1,threshold value of competition spread m2 and propagation depth h was set.With the values of m1,m2 and propagation depth h changing,experiment showed that opposing public opinion showed different distribution,and leading different final result of public opinion dissemination.
