System Construction and Influence Analysis of Public Opinion Risk Assessment Indices for Agricultural Public Emergencies
摘要
Abstract
The efficacy of the response to Internet public opinion on agricultural public emergencies is closely associated with farmers'livelihoods and the overall state of agricultural prosperity and rural revitalization.The establishment of a risk assessment system for Internet public opinion on agricultural public emergencies can offer powerful decision-making support for the prevention and emergency treatment of Internet public opinion on agricultural public emergencies.Firstly,grounded on the theory of information ecology,this paper dissects the factors influencing the risk of Internet public opinion on agricultural public emergencies and constructs an evaluation index system integrating the traits of rumors.Secondly,the index weight is ascertained by the AHP-EWM method which combines subjectivity and objectivity.Finally,based on 98 678 Weibo public opinion data of agricultural public emergencies,cluster analysis is conducted on 6 640 grouped data aggregated by hour,and a four-level classification criterion is established for the risk of Internet public opinion on agricultural public emergencies.The influence analysis is carried out from the dimensions of agriculture-related information person,agriculture-related information resource,and agriculture-related information environment.Based on the results of the analysis of the influence,this study summarizes the governance proposals for Internet public opinion on agricultural public emergencies:focusing on the monitoring of Internet public opinion on agricultural public emergencies during key periods;conducting real-time monitoring of key indicators to prevent public opinion from escalating from low risk to high risk;and establishing a real-time rumor-refuting and information-release mechanism.关键词
