中文摘要: 在食品安全事件频发的社会背景下,食品安全网络舆情作为公众参与食品安全监管的重要平台,对监控与预警食品安全风险具有积极意义。但也应该看到,食品安全网络舆情中不乏具有煽动性的虚假信息,极易造成舆情的爆发,引起社会恐慌,严重危害社会稳定。基于对我国社会风险特征与未来发展趋势的认识,分析食品安全网络舆情的基本内涵特征,揭示我国食品安全网络舆情所面对的重大问题;建立食品安全网络舆情网民微观行为分析框架,在网民行为影响因素分析的基础上,建立食品安全网络舆情协同演化机制的宏观分析框架,探讨食品安全网络舆情的演化机理;基于话题传播与意见演化协同作用的动力学特性,引入加权网络进行动力学仿真分析,研究政府对舆情演化中群体行为的引导与控制策略。其意义在于,综合考虑网民行为的影响因素,并从话题传播与意见演化两个方面研究网民的心理与行为特征,有助于更全面地认识舆情演化机理,对提高政府应对策略的科学性具有重要意义。

英文摘要: In the context of food safety incidents frequent occurrence,food safety network public opinion as an important platform for public participation in the supervision of food safety,and has positive significance for monitoring and early warning of food safety risk.But also should see, food safety network public opinion have false information and provocative ,extremely easy to cause the outbreak of public opinion,cause social panic,serious harm social stability.Based on the knowledge of the social risk characteristic and the future development of our country ,analyze the characteristics of food safety network public opinion,reveals the major problems of food safety network public opinion in China.Establish the microscopic behavior analysis framework of food safety network public opinion ,on the basis of analysis on the influence factors of netizen behavior,build the macro analysis framework of co-evolution mechanism of food safety network public opinion,investigate the evolution mechanism of food safety network public opinion .Based on the dynamic characteristics of synergy between topic spread and opinion evolution,introduction of weighting network for dynamics simulation,investigate the guidance and control strategy for netizen in the network opinion. The significance of research is that the comprehensive consid
