Research And Judgment And Guidance Strategies For The Decline Of Public Opinion On The Internet In Emergent Public Events

In the era of big data,network governance has become an important link in the construction of a network power.We are in a "media society",and everyone can become the main body of information expression and opinion dissemination.The gathering of these voices to form Internet public opinion affects all aspects of us,and even hinders the formulation and implementation of public policies.However,public emergencies that occur from time to time are more likely to form far-reaching online public opinion.Research on this has important theoretical and practical value.Based on related theories such as the network public opinion system theory and the network public opinion life cycle theory,and based on the review and summary of the existing literature,this research divides the public opinion of emergencies into the incubation period,the proliferation period,the outbreak period and the recession period;focus on emergencies Initiating public incidents during the decline period of online public opinion,and constructing an index system for studying and judging the decline period of public opinion on public emergencies;using Python crawler technology to obtain data,introducing SKEP algorithm,simulation based on RBF neural network,and providing emergency public through multi-case empirical analysis The guiding strategy of event network public opinion.Studying and judging whether public opinion on public emergencies has entered a period of decline can provide theoretical guidance for the government’s monitoring and guidance of online public opinion.Finally,the research and judgment index system can be used to promote the monitoring and management of public emergencies during the decline of online public opinion.Research conclusions show that: for the negative public emergencies online public opinion that has not yet entered the recession period,mainly by diverting the attention of the main body of the public emergencies;speeding up the process of dealing with the object of the public emergencies;guiding public emergencies The trend of the network public opinion ontology;strengthening the supervision of the network public opinion media in emergencies and other means to reduce heat treatment has accelerated the decline into the period.For non-negative public emergencies that have not yet entered the recession period,the network public opinion is mainly guided,and its positive role is played to make it naturally decline.Regarding the public opinion of public emergencies that have entered a recession period,appropriately reduce monitoring efforts,allocate resources rationally,and respond to demands in a timely manner to prevent a rebound of public opinion during the recession period.The research results have important practical significance for improving the government’s online public opinion guidance level,strengthening the government’s emergency management capabilities,promoting the timely and effective resolution of public crises,and the overall advancement of the building of a network power.
