Research On Communication Mechanism Of Emergency Weibo Public Opinion Based On The Integration Perspective

Nowadays,the vigorous development of Internet information technology has caused the rapid changes of social environment and social structure at home and abroad,brought about new social forms,and has made human society realizing the combination of the real world and the Internet,entered the era of data integration.The network public opinion generated in the data era not only produces information of various social events,but also triggers various hidden social and psychological emotions.Furthermore the emergency public opinion network dissemination integrates the media,practice,society and other multiple levels,which makes the public opinion dissemination an extraordinary impact.Therefore,the study is based on social and historical functions at the macro-level of network public opinion,and the function of information analysis and knowledge mining at the micro-level,to explore the emergency dissemination mechanism of public opinion on Weibo deeply and detailedly.The purpose of the study is to build a public opinion information knowledge think tank,to establish the public opinion processing mechanism and assistant decision-making management system of the government,news medias,enterprises and other institutions,and improve the research system of theories and methods in sentiment information management.And meanwhile the paper interprets public opinion,observes the trend of public opinion,so as to explore the impact of information dissemination of public opinion events on social development,and deepen the significance of theoretical research in the field of public opinion dissemination.Therefore,the research on the dissemination mechanism of Weibo public opinion emergency based on integration perspective is not only the demand of social reality,but also the exhibition of social movement law under the development of the era.This research based on the concepts of communication function and information essence,etc,and also based on the multiple dimensions and factors,such as communicators,publishers,publishing contents and communication network relations.And the research adopts theories such as complex network theory,life cycle theory,communication dynamics theory,and methods as mathematical statistics method,LDA topic mining model,and simulation tool for modeling,so the research deeply explores the characteristics of various information elements,the interaction between elements,the structure of communication relations,the characteristics of communication elements and so on,which all in the communication process of public opinion emergency.This paper aims to explore the law of public opinion information dissemination and reveal the mechanism of communication,so the main research works and achievements are summarized as follows:(1)Research on the user factors of Weibo emergency public opinion.The paper mainly studies the user behavior,user characteristics,user impact and others.The paper finds the statistical characteristics of user behavior,the most active microblog users in the dissemination,as well as the most influential users in the communication and other conclusions.(2)Research on theme topics mining of different disseminators in the period of Weibo emergency public opinion dissemination.The paper studies hot topics mining of mass published information and user comments in Weibo sentiment period,and finds the topics structure,mainstream views,the themes communication context,and the differences in the focus of topic propagation.(3)Research on the complex network structure and evolution of Weibo emergency public opinion dissemination.The paper researches the communication network topology structure,finds the characteristics of the whole network structure and communication nodes,meanwhile the paper studies the dynamic network evolution,also finds the dynamic expression forms and trends of network structure and nodes.(4)Research on SIR model and simulation of emergency public opinion dissemination on Weibo.The paper constructs SIR model of information diffusion to learn the transition state of individuals in the dissemination process,then adjusts the main parameters of the simulation model through Matlab programming,and finds the sensitivity reaction of propagation and diffusion.(5)Research on the management strategy of Weibo emergency public opinion dissemination.The paper researches regulatory strategies at strategic level and uses SWOT analysis method to analyze the advantages,disadvantages,potential opportunities and threats of Weibo public opinion communication management in depth and details,then puts forward corresponding countermeasures on the basis of these aspects.
