On propagation of sports public events based on social network structure

In today's society public events happened frequently which often bring adverse effect to social events.As for the sports events with high degree of attention,public opinion emergency often bring irreversible effects on the sporting events.Using social network analysis method,this paper studied the sports public opinion transmission characteristics and paths,analyzing the characteristics of the spread of public opinion.Taking 2012 Guangzhou marathon event as the research object,an empirical research was done.Results show that in the marathon event propagation,the verall density of network is higher,the traditional media and the self-mediaed information interacted frequently;all the actor information interchange distance is shorter,information transmission speed quickly.Actors in the whole network are in relatively independent status and role,despite the existence of structural holes,but the binding force is relatively small,the information transmission has little constraints and most are transimitted in a direct way.
