Research On The Evolution Of Network Public Opinion Of Large-scale Sports Events Considering The Factors Of Opinion Leaders

Large-scale sports event is an important platform for countries to show their soft power.The public opinion crisis caused by large-scale sports events will attract worldwide attention.If handled improperly,it will have a negative impact on the national image and the state sports undertaking.Therefore,it is extremely important to explore the internal mechanism and general pattern of the public opinion triggered by large-scale sports events,especially from the perspective of public opinion guidance and control,so as to formulate targeted control strategies.Nowadays,Sina Weibo,Hupu Sports and other social network platforms play a dominant role in public opinion generation and evolution.In these kinds of platform,everyone is capable of information producing,diffusing and consuming,performed the characteristics of homogeneity.However,due to their different resource endowments,individuals show strong heterogeneity in the process of information diffusion and aggregation.In general,it shows the characteristic of complexity with network communication structureAgainst this background,this study takes the online public opinion of large-scale sports events as the research object,and considers opinion leaders as the research entry point.This paper tries to break through the "static" mode of previous sports public opinion research,describes the influence characteristics and action mechanism of opinion leaders through the "dynamic" method and numerical simulation method,and puts forward some suggestions to prevent and control the negative public opinion in large-scale sports events.The main research contents and conclusions are summarized as follows:First of all,On the basis of combing relevant researches and based on hot public opinion cases of large-scale sports events in recent years,the characteristics of public opinion evolution of large-scale sports events are extracted from the perspective of this research.Besides,the research hypothesis is put forward.Then,sina weibo was used as a platform to select cases and real data were collected to analyze and verify the rationality of the research hypothesis.In the model construction stage,based on the traditional Deffuant-Weisbuch dynamic model and referring to the above hypothesis,an improved model considering the characteristics of sports opinion leaders and audience groups is proposed.The BA free-scale complex network was constructed by modeling and simulation of complex system,and opinion leaders were identified.The simulation results were presented by image for discussionThe results show that Opinion leaders can guide the tendency of public opinions,accelerate the convergence of network opinions and avoid the polarization of network opinions.The limitation of opinion leaders is that their in fluence on the fanatical group is weak and they cannot break through the limit of the trust threshold of the group.The difference in influence of different opinion leaders is related to the professional characteristics of opinion leaders.Based on the research conclusions,the following suggestions are put forward:attaching importance to the role of opinion leaders in guiding public opinion;Judging opinion leaders from the perspective of public opinion events in specific sports events;opinion leaders’ views should avoid standing opposite to the audience.Promoting media literacy among the public;Consider the audience groups of different events and avoid the "homogenization"public opinion processing strategy.The research results are of certain significance for people to deeply understand the internal mechanism of the formation and evolution of network public opinion in large-scale sports events,and to explore the role of opinion leaders from multiple perspectives provides new ideas for the further study of network public opinion in sports events.At the same time,numerical modeling and simulation as the research method strengthens the current network sports public opinion research of the systematic thinking,enrich the current speculative,case analysis and other static analysis of the research mode.
