Holding big sports events has become an important platform for concentrating on the cultural strength of a country or region.Social media,represented by Weibo,has become an important field for event network communication.This article quotes the theory of relational networks,and uses the "Wuhan Military Games Opening Ceremony" as a case,Using UCINET social network analysis software,by analyzing Weibo platform through the multi-valued directed relationship of "follow" and "being followed" Establish a 1-mode network structure model.Use relevant social network analysis methods to identify opinion leaders in the process of event dissemination.Analyze the impact of the relationship network structure on the dissemination of sports event information from the local and overall levels.Explore the internal structure of the network.Relationship characteristics,put forward an effective path that is conducive to the spread and diffusion of sports events,and improve the influence of sports events.The study found that the topical relationship network at the opening ceremony presents a "low-density,short-distance" network propagation structure characteristic,which can achieve rapid information dissemination.There are a few central nodes in the network.Ordinary nodes get information around the central nodes.The central nodes are closely connected with each other and interact frequently.They play a role in guiding public opinion and forming small groups in the network.In addition,the distribution of fan groups in the network further weakened the trend of network-centric clusters,leading to a decline in cohesion within the network and a close connection between members,but the ability of information to radiate and diffuse outwards was enhanced.according to the characteristics of the network structure of the dissemination of public opinion at the opening ceremony of the Military Games,this article believes that feedback and interaction channels should be strengthened and efforts should be made to tap emerging nodes with growth potential.While focusing on expanding thescope of information dissemination,it is also necessary to strengthen cohesion within the group;This method of communication avoids information gaps caused by the lack of connection between different audience segments and improves the transparency and fluency of information dissemination.
