| 摘 要： | 微博网络中信息的"裂变式"传播模式对已有舆情传播模型提出挑战。为有效地揭示出微博用户关注关系所形成的复杂网络中舆情传播演化的机理,以有向无标度网络为载体提出舆情传播的SIRS模型,该模型综合考虑微博的传播特性以及舆情话题的衍生性等因素,并对模型进行仿真分析,其结果可以验证模型的有效性。

| Abstract: | Fission mode of information transmission in the micro-blog network presents a challenge to the existing public opinion propagation model.In order to depict the mechanism of the public opinion transmission in the complex network formed by users’ attention relationship in micro-blog,the paper proposes an SIRS model of public opinion propagation based on the directed BA network.The model considers the propagation characteristics of micro-blog,and derivatives of public opinion topics and other factors comprehensively.The simulation results can verify the validity of the model. |
