舆论危机的异化极化效应研究

随着Web2.0时代的到来,网络媒体逐渐成为舆论生成、传播和交锋的主阵地,舆论危机的形成及其异化也成为日益突出的社会风险问题.本文以舆论的异化演化机理为研究对象,通过梳理典型事件舆论话题的异化过程,对其基本内涵、表现形式和演化模式等进行系统总结.随后,研究以舆论超网络模型为基础,借鉴社会影响理论的基本原则,提出舆论异化机理的极化算法,并对其具体流程进行解析和实现.最后,本文以“7·23甬温动车事故”为例,对舆论危机的异化极化过程和影响因素进行系统仿真和实证分析.

Alienation mechanism and polarization effect of public opinion crisis

Since the arrival of the Web2.0 era,network media gradually dominates public opinion generation,dissemination and exchange.The evolution and alienation of public opinion crisis has become a serious social problem,which received increasing attention from social scientists and the general public.Therefore,the paper chooses the alienation mechanism of network public opinion crisis as the research object.After collecting and sorting public opinion crisis incidents in recent years,the basic concepts,expression forms,and specific patterns of public opinion alienation are systematically summarized.Then,under the architecture of public opinion supemetwork,the polarization algorithm of public opinion crisis alienation is proposed,which can be used to analyze the driving factors of alienation mechanism.Besides,the paper also presents a concrete scheme and program codes of the polarization algorithm.In the case study section,the polarization process and influencing factor are discussed by using the polarization algorithm.
