time,which more truly reflects social conditions and public opinion,as well as people’s attitudes and emotions towards some hot events.For sports events,its network public opinion also plays an important role in the holding of events and the development of competitions.If online public opinion can develop in a positive direction and does not involve a crisis of public opinion,then the government or the organizer of the event can use public opinion to attract the attention of netizens,promote sports competitions,and spread the spirit of sportsmanship.But on the other hand,"violent incidents" and "violent conflicts" in sports arenas occur from time to time;Abnormal performance of athletes,unsatisfactory results,unfair referee penalties,etc.will cause dissatisfaction and negative emotions among netizens,resulting in a crisis of public opinion.Therefore,how to grasp the trend of online public opinion of sports events from massive text data,understand the development opinions of

text of the 14 th National Games presents an entertaining and emotional expression;Online public opinion information shows obvious group consciousness in the process of aggregation;No matter at what
