融合主题的社交媒体舆情SEIR传播模型构建与仿真研究

Construction and simulation of a SEIR propagation model for social media opinion with converging topics

社交媒体改变了当下舆情事件应对治理方式,本文旨在融合主题因素探究在舆情传播过程中各因素对传播演化的影响,揭示社交媒体平台上舆情传播的特点,在舆情治理领域为相关职能部门提供参考借鉴。为抓住社交媒体舆情传播演化的关键,本文融合主题因素,基于传播演化SEIR模型,引入主题热度和用户兴趣度构建改进型SEIR模型并进行仿真研究,探查各个参数变量对传播的影响。仿真实验刻画了主题热度和用户兴趣度等因素对舆情传播的影响,体现了主题热度和用户兴趣度在监测、预警舆情传播演化中的重要价值,进而为政府和相关部门治理舆情提供参考和借鉴。

Social media has revolutionized the way public opinion responds and is governed.The aim of this paper is to explore the impact of various factors on the evolution of communication during the process of public opinion communication by incorporating thematic factors.It seeks to uncover the characteristics of public opinion communication on social media platforms and offer guidance to relevant functional departments in the field of public opinion governance.In order to capture the essence of the evolution of social media opinion dissemination,this paper integrates thematic factors and improves the SEIR model of dissemination evolution by introducing topic hotness and user interest.A simulation study is conducted to investigate the influence of each parameter variable on dissemination.The simulation experiments highlight the influence of factors such as topic hotness and user interest on the spread of public opinion,which demonstrates the vital importance of monitoring and warning the evolution of public opinion spread through topic hotness and user interest.Therefore,it provides valuable references for the government and relevant departments to manage public opinion.
