| With the rapid development and popularization of network technology,the importance of social network in people’s life is increasing day by day,and it has become an important medium for information sharing and interaction.Due to the unique characteristics of information interaction in social networks,such as fast interaction and wide range,online rumors inevitably begin to spread in cyberspace.At present,the academic community pays close attention to the problem of social network rumors and rumors reputation,which has become a research hotspot and also faces many challenges.In order to gain an in-depth understanding of the optimization of the effect of rumors refutation in social networks and the guidance of online public opinion,this paper conducts relevant research on the effect of rumors refutation in social networks under public emergencies.This paper clarifies the connotation of the effect of social network rumors and rumors refutation by sorting out the related researches on social network rumors and rumor refutation effects.The paper is divided into six chapters.Based on grounded theory,it deeply explores the influencing factors and evaluation effects of social network rumors and rumors refutation under public emergencies.Chapter 1introduces the research background and the current research status of social network rumors and rumors refutation effects at home and abroad so as to explain the research significance,research methods and research innovations of this paper.The second chapter mainly describes social network rumors and their characteristics,social network rumors and their methods,related concepts of grounded theory and information ecology.The third chapter mainly analyzes the influencing factors and action paths of social network rumors and rumors.The research method selects the qualitative research method of grounded theory,and draws the research conclusion through the coding step by step,and finally gets 22 initial concepts,12 categories and6 main categories.On this basis,this paper summarizes and integrates three dimensions—subject,information and channel,and then constructs the SIC model analysis framework for the influencing factors of rumor refutation effect,and deeply analyzes the relationship between the main categories and the effect of rumor refutation.In addition,it is particularly important to analyze the relationship between various influencing factors.This research uses the Interpretative Structural Modeling Method and MATLAB matrix to integrate the influencing factors into three levels,and build a hierarchical structure model of the influencing factors of the rumor refutation effect.On the basis of supplementing and sorting out the previous research results,based on information ecology theory,chapter 4 constructs an evaluation index system for the effect of social network rumors and rumors refutation,and uses the analytic hierarchy process to calculate the index weights,and then conduct empirical research.The fifth chapter explores the promotion strategy of social network rumors from the four dimensions of information ecology theory.Chapter 6 summarizes the research conclusions,and analyzes the shortcomings and future prospects of this research.At the theoretical level,based on the grounded theory research method,this paper constructs the influencing factor model and hierarchical structure model of social network rumor refutation effect under public emergencies;from the perspective of information ecology theory,constructs the social network rumor refutation effect evaluation index system.At the practical level,this paper conducts an empirical study on the effect of specific social network rumors and rumors refutation,and finally proposes a strategy to improve the effect of rumors,in order to optimize the guidance of online public opinion and purify the social network space. |
