Research on the Official Media Guidance of Online Public Opinion Based on the Public Opinion Topic Strategic Diagram
In view of the problem that the official media fails to actively guide public sentiment and grasp the key points of public opinion in guiding online public opinion,this paper proposes to construct a public opinion topic strategic diagram to assist the official media in guiding public opinion.In this method,the public opinion topics in public discussion and official reports are taken as the analysis unit,and the LDA topic modeling and Hownet sentiment dictionary are integrated to find public opinion topic discovery and sentiment classification,and by defining three quantitative indicators of public opinion topic sentiment value(TE),topic usage degree(TU)and topic attention degree(TA)of public opinion,two sub-graphs of public opinion topic strategic diagram and public opinion topic supply and demand strategic diagram are proposed.Finally,it was verified in combination with the hot network public opinion event of"Qiqihar Stadium Collapse".
