摘 要: 以突发事件网络舆情演化为对象展开研究,系统介绍网络舆情演化的相关方法研究,并对突发事件网络舆情的特征进行定义和阐述。在此基础上,采用传染病模型研究突发事件网络舆情演化趋势,构建突发事件网络舆情演变SIR模型,定义演化规则并给出模型的求解步骤。最后,利用Matlab仿真软件对网络舆情演化趋势进行分析,结果表明所构建的模型正确、有效,可用于突发事件网络舆情的演变趋势分析。
关 键 词: 管理工程;网络舆情;SIR;突发事件;演变趋势

Abstract: This thesis introduced the related methods about evolution of web public opinions systematically regarding emergency’s web public opinions as an object, and defined and explained the characteristics of emergency’s web public opinions. On this basis, this paper used the SIR epidemic model to research the evolutionary trend of emergency’s web public opinions, constructed the evolution SIR model of the emergency’s web public opinions, and defined the evolution of the rules and gives steps of solving. At last, this paper used the Matlab software to analyze the evolution of emergency’s web public opinions. The results proves that this model is proper and effective, which can be used to research the revolution of emergency’s web public opinions.
Key words: management engineering; web public opinions; SIR ; emergency; revolution trend
