摘 要:[目的/意義]采用当前方法分析网络舆情危机演变特征时,无法明确网络舆情传播过程中演变特征影响因素之间的因果关系,导致分析结果的灰色关联度低、小误差概率小、均方差比大,因此研究了网络舆情危机演变特征及其预警方案创新方法,采用系统动力学对网络舆情危机演变变量和影响因素进行仿真和建模,获取网络舆情危机演变的主要影响因素,结合网络舆情传播热度与各因素之间的因果关系分析网络舆情传播系统。[方法/过程]结合Verhulst模型和灰色理论模型构建灰色Verhulst预测模型,根据各影响因素之间存在的因果关系分析网络舆情危机演变特征,根据分析结果提出构建信息汇集分析机制、预警机制、信息发布机制和引导机制的预警方案。[结果/结论]实验结果表明,采用所提方法分析网络舆情危机演变特征时,分析结果的灰色关联度高、小误差概率大、均方差比小。

Abstract:[Purpose/Significance]When the current method is used to analyze the evolution characteristics of network public opinion crisis,the causal relationship between the influencing factors of the evolution characteristics in the process of network public opinion dissemination can not be clarified,which leads to the low grey correlation degree,small error probability and large mean square deviation ratio of the analysis results.Therefore,the evolution characteristics of network public opinion crisis and the innovation method of early warning scheme are studied,and the system dynamics is used to analyze the network public opinion crisis the evolution variables and influencing factors are simulated and modeled to obtain the main influencing factors of the evolution of network public opinion crisis.Combined with the causal relationship between the popularity of network public opinion and various factors,the network public opinion communication system is analyzed.[Method/Process]Combined with Verhulst model and grey theory model,the grey Verhulst prediction model is constructed.According to the causal relationship between the influencing factors,the evolution characteristics of network public opinion crisis are analyzed.According to the analysis results,the early warning scheme of information collection analysis mechanism,early warning mechanism,information release mechanism and guidance mechanism is proposed.[Result/Conclusion]The experimental results show that,when the proposed method is used to analyze the evolution characteristics of network public opinion crisis,the grey correlation degree is high,the small error probability is large,and the mean square deviation ratio is small.

我国经济结构在社会转型期间发生了较大变化,使得社会生活逐步趋向多元化和复杂化[1]。在此期间一些矛盾逐渐暴露在社会大众面前,在表达渠道多样化的情况下,开始在网络平台中反映各种社会问题。分析代表性较强的公共事件可知,民意表达空间随着社会的进步不断扩展,群体性事件的出现往往会促进网络舆情的演变,已经成为一种比较突出的社会问题,部分不良事件对构建社会主义和谐社会产生了不利影响[2]。……
