Study On Coupled Social Network Public Opinion Communication Based On Improved SEIR

Abstract

Since the media era, online public opinion is cross-spreading in multiple social networks, and studying the law of public opinion dissemination in coupled social networks is beneficial to the governance of public opinion. It first uses the scale-free network to construct Weibo and WeChat networks, and the Weibo and WeChat two-layer coupled social networks were constructed by setting specific node connection methods and network coupled rates. SEI <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> R model is established, and the propagation law of the public opinion WeChat and Weibo coupled double-layer network is studied through matlab simulation. Experiments show that the constructed SEI <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> R can better simulate the public opinion dissemination process in the network. The dissemination of public opinion information on the two-tier network enhances the influence of public opinion, the network coupling rate, the inter-layer transmission probability, and the direct immunity rate of netizens It has a significant impact on the spread of public opinion.
