Study On The Derivation Mechanism Of Internet Public Opinion Information Ecology

Internet public opinion plays an increasingly important role in conveying public opinion,supervising rights protection,and expressing demands.As network tools such as mobile clients and smart phones become more and more popular,network technologies have become more and more advanced,Web platforms such as Weibo and Wechat have become more and more popular,the public information on the Internet has become more unstable,and the ecological information environment of Internet public opinion has become more easy to be destroyed,and the negative topics and cyber violence that continue to emerge have exerted great pressure on social governance.Scholars have studied Internet public opinion from different perspectives,including defining basic connotations,revealing evolutionary mechanisms,constructing communication models,and proposing early warning methods.However,judging from the current research results,scholars value the single index of the popularity of topics in the evolution of online public opinion.They rarely pay attention to the conversion and replacement relationship between the public opinion community and the resonance relationship between the same type of events.Based on this,combing the research results of Internet public opinion and information ecology at home and abroad,this paper has comprehensively applied research methods such as literature survey,information ecology,virtual ethnography,and MATLAB simulation,from the perspective of information ecology.Starting with it,we will focus on researching the ecological derivation mechanism of Internet public opinion information.First of all,it explores the relationship between the ecologically derived factors of Internet public opinion information and attempts to establish the connection between the derived factors and the topical community.According to the game between positive and negative ecological effects,the ecological derivative of the Internet public opinion information is decomposed into a horizontal derivative method and a vertical derivative method,and a framework is constructed for the third and fourth chapters to lay a solid foundation for research.Chapters 3 and 4 respectively reveal the horizontal and vertical derivation mechanism of the ecological information of the Internet public opinion.They define the determinants of the two derivatives and analyze the derivation process of the two derivatives.Based on the analysis the process,The ecological STR model and the ST~2R model of the network public opinion information are established respectively,and the analysis of the ecological derivation mechanism of the network public opinion information is implemented based on the MATLAB simulation.Finally,combined with the red,yellow and blue event network public opinion,the data is collected from the Sina Weibo API interface for case analysis.The validity of the research model is verified by comparing the ecological situation of the red,yellow and blue event network public opinion information with the derived situation of the parameter setting simulation.The results show that this study proposes that the mechanism of ecologically derived information of the public opinion information of the Internet has certain practicality and rationality.According to the research results,it provides theoretical support and decision-making reference for the ecological management of public opinion information.
