Study on the Grid-based Early Warning Model for Online Rumors of Public Health Emergencies
In order to improve the problem of low efficiency and insufficient reliability of online rumors early warning,a grid-based early warning model for online rumors of public health emergencies is established.Firstly,the depth of confusion of online rumors to individual audience is identified longitudinally by quantifying the basic characteristics of online rumors based on the grey-weighted correlation analysis.Secondly,the spread of online rumors to audience groups is predicted horizontally combined the dynamic game of incomplete informa-tion with simulation.Finally,the assessment results of both vertical and horizontal dimensions are integrated to define the overall social influence of online rumors,and a visual four-level early warning classification for mild,warning,severe,and danger is carried out,and four emergency management and control strategies of delay,suppression,confronation and suppression are correspondingly proposed.The case of"Shuanghuanglian"is taken as an example to verify the effectiveness of the online rumors grid-based early warning model and its choke tactics.In terms of theoretical research value,it is the first time that the dual perspectives of"identification-warning"and"dissemination-warning"are combined to predict the early-warning level of the overall social influ-ence of online rumors.Based on the interaction between information and audience,the information vagueness of online rumor is estimated more comprehensively,and both the individual cognitive judgment of the audience and the game psychology of the audience group are considered in the evaluation of the spread of online rumors.At the same time,the whole process of this study relies on big data,artificial intelligence and other automatic technologies to improve the objectivity of the evaluation of social influence of online rumors.On the basis of visualizing the four-level warning(mild level,warning level,severe level and danger level)of the overall social influence of online rumors,four emergency management and control strategies are proposed respectively,which promoted the study of online rumors governance.
