Analysis On The Sentiment Trend Of Public Opinion During The Epidemic Period

Since COVID-19 broke out in 2019,the Chinese people,under the leadership of the Communist Party of China(CPC),have made all-out efforts to combat the epidemic.From the end of December 2019 to the beginning of April 2020,after several stages of epidemic development and anti-epidemic work,the COVID-19 epidemic has been effectively controlled,and China has entered the stage of epidemic prevention and control normalization.In the several stages of the development of the epidemic,the public perception,public sentiment and public opinion of the epidemic are also constantly changing,and different public opinions have brought different degrees of impact on the epidemic prevention and control work.At present,researches on public opinion during the COVID-19 epidemic are mostly focused on social psychology,rumor spreading,public opinion guidance,epidemic response,opinion leaders,etc.,and lack of researches on public emotion.However,the research in this paper just fills the gap in this field.On the basis of the existing research,this paper crawls the articles published by the official public opinion field represented by People’s Daily and the civil public opinion field represented by Tencent News and netease News during the epidemic period through the web crawler.First,it is found through text clustering that the two public opinion fields cover four topics,namely epidemic prevention and control,anti-epidemic donation,anti-epidemic heroes and resumption of work and production.But the focus on each subject varies.Combined with the Chinese Sentiment Vocabulary Ontology Database released by Dalian University of Technology,the emotional state of the two public opinion fields was analyzed.Based on the dual-path model,the influence of the emotional state and body theme on the communication effect of the article was analyzed.Finally,based on the agenda setting theory and combined with the analysis results above,the linkage analysis of the two public opinion fields was conducted.Optimized measures for public opinion guidance in major public health events are proposed for the government,and coping methods for individuals to influence public opinion in major public health events are proposed.In combination with the linkage analysis results,it was found that the public opinion guidance mechanism of the official public opinion field was somewhat deficient in the first and second stages of the development of the epidemic,which indirectly led to the spread of negative public opinion and frequent rumors.However,in the process of adjusting the public opinion guidance mechanism,measures such as the establishment of the official platform to counter rumors and the introduction of expert opinion leaders played a strong role.According to the dual-path model,we find that articles that can arouse users’ emotional resonance and satisfy users’ interests and hobbies can stimulate users to conduct secondary communication.In addition,the publication time,text form and push position of the article all have an impact on the dissemination effect of the article.Therefore,this paper holds that when major public health events occur,the government should ensure early warning,speed up the process of obtaining the truth and scientific demonstration,and help the public to build a correct cognition and ease emotions by combining the methods of positive guidance,Internet rumour debunking platform and expert opinion leader guidance.So as to achieve the purpose of maintaining social stability,avoiding public opinion rebound and concentrating on dealing with public health events.In addition,the government also needs to pay attention to the way and details of information dissemination and expand the coverage of information.As for the measures taken by individuals in major public health events,this paper suggests that individuals should pay attention to the official public opinion field,ensure that they can obtain accurate and authoritative information in a timely manner,take the initiative to obtain information rather than passively accept it,and remain objective and calm when participating in the discussion and expression of opinions in the public opinion field,and not partial to the opinions inconsistent with the official line.
