摘要
[目的/意义]文章旨在探究移动社交网络中群体行为对用户个体的影响方式与效果。[方法/过程]对SEIR模型进行优化与改进,增加群体规模、从众效应和社会强化效应的影响机制,对4类群体在社会网络中的舆情传播机制进行动态分析。[结果/结论]在无标度网络下进行仿真分析,结果表明,规模大的社群舆情传播会对规模小的社群产生间歇性影响,群体从众效应对信息传播深度和广度有显著影响,社会强化效应在一定范围内会增加信息传播的概率。
[Purpose/Significance]This paper aims to explore the influence mode and effect of group behavior on individual users in mobile social networks.[Methods/Process]The SEIR model was optimized and improved to increase the influence mechanism of group size,conformity effect and social reinforcement effect,and the public opinion communication mechanism of the four groups in the social network was analyzed dynamically.[Results/Conclusion]The simulation analysis was carried out based on scale-free network.The simulation results showed that the large-scale community public opinion communication would have intermittent impact on the small-scale community,the crowd effect had a significant impact on the depth and breadth of information dissemination,and social reinforcement effect would increase the probability of information dissemination in a certain range.
