Research On Time-Frequency Statistics Of Public Opinion Information On Internet

With the development of information technology and the popularization of the Internet,the frequency of online public opinions has been increasing,and the pressure on management control has also been increasing,as an important measure to promote and solve online public opinion,information disclosure has aroused the continuous concern of all walks of life.However,in the face of the increasing number of public opinions on the Internet,the traditional ways of information disclosure by government agencies are faced with such shortcomings as untimeliness in time,limited space for dissemination and shortage in the frequency domain of publication,it's hard to reach an audience with a single media.The Internet media has overcome the time and frequency limitations and become a new subject of information disclosure in the process of dealing with Internet public opinion efficiently in coordination with the government.As of June 2019,China has an internet population of 854 million and an Internet penetration rate of 61.2 percent.Internet dissemination is playing an increasingly important role in promoting information disclosure.By setting up online accounts together with the online media,the government integrates key information such as the progress of the online public sentiment case and the investigation results after the government's intervention,and carries out multi-party real-time disclosure and reporting of online information together,they form a new mode of network information disclosure,which endows the information disclosure with a new connotation of the new era.Compared with the traditional way,the rhythm of information disclosure in time domain and frequency domain also has new characteristics.The government and the media network information disclosure behavior,respectively in the time domain and frequency domain performance of induction and statistics,can enhance the current network public opinion information disclosure of the new understanding,to help the government improve the network public opinion information disclosure mechanism.More and more scholars carry out research on the information disclosure of network public opinion,mostly focusing on the mechanism of information disclosure,the strategy of government information disclosure and so on.This paper mainly reviews the literature from two aspects of network public opinion and information disclosure,then gives the definition of network public opinion information disclosure,analyzes the new characteristics and new subjects of network public opinion information disclosure,the time-frequency statistics is classified according to its components,and the time-frequency statistics framework is constructed from time-domain statistics and frequency-domain statistics.Firstly,in the time domain part,the physical concept is introduced to set the research field for the time element of information disclosure,which is the main content element of time domain statistics from the aspects of the first renewal time,the setting and distribution of time point.By using the data of Sina Weibo,this paper analyzes the information disclosure of mainstream media and network media,and obtains the comprehensive evaluation of network information disclosure from the perspective of time domain.Secondly,in the frequency domain,frequency performance,classification and evolution as three dimensions of analysis.Combined with the data of Sina Weibo,this paper classifies and compares the frequency of public opinion information disclosure,and obtains the overall evaluation of public opinion information disclosure in frequency domain.Finally,the article through the online public opinion information open time-frequency statistics,finally proposed the corresponding time-frequency choice strategy,hoped that in the process of dealing with the network public opinion,this selection strategy can play a guiding role in the online public opinion information disclosure.
