基于社群用户特征的网络舆情传播趋势分析

Research on the Development Trend of Internet Public Opinion Diffusion Based on Network Community User Characteristics

[目的/意义]从社会网络视角出发,探究网络社群用户特征对舆情传播发展趋势的影响作用,旨在进一步揭示网络舆情传播的内在发展规律。[方法/过程]构建基于强弱关系的阈值模型,采用Agent方法,在无标度网络中模拟调节焦点、关系强度、网络异质性、社群认同等因素对舆情传播水平和速度的影响作用。[结果/结论]随着时间的增加,舆情传播水平呈现出先增长后趋于平稳的趋势,促进焦点型网络的发展水平高于防御焦点型网络;在适当的网络异质性条件下,促进焦点型网络的舆情传播水平和速度可以达到最大值;弱关系环境更有利于促进焦点型网络的舆情传播水平和速度的提升。

[ Purpose/Significance ] This research tries to study the influence of network community user characteristics on the development trend of Intemet public opinion diffusion from the perspective of social network,in order to further reveal the inherent law of the develop- ment of network public opinion. [ Method/Process] Building the threshold model with strong tie and weak tie, we introduce the theory of social network based on agent modeling to simulate the influence of regulatory focus, tie strength, community structure, social circle iden- tity and other factors on the public opinion diffusion in scale-free network. [ Result/Conclusion] With increasing time, the public opinion diffusion level shows a growth trend first then a smooth trend, and the level of promotion network are higher than prevention network; With the appropriate network heterogeneity, the promotion network＇ s public opinion dissemination level and speed can reach a maximum value; weak ties environment is more advantageous to the level or speed growth of public opinion dissemination in promotion network.
