Abstract:

To date, researches on the model and its evolution mechanism of public opinion dissemination have largely focused on two separate networks perspectives, namely, online social networks (online networks) and offline physical contacting networks (offline networks). However, public opinions in the real-world are disseminated on online social networks and offline networks simultaneously. Hence, a single online or offline network perspective is not sufficient to capture and reveal transmission dynamics model of public opinions in line and offline networks. The results of experimental simulation and case validation well support the reality. In the current research, we develop a model based on bilayer-coupled networks including both online and offline networks. Moreover, drawing on the theories of communication and social psychology, we propose the symmetric and asymmetric dissemination mechanisms for promotion and inhibition between onoretical analysis by showing that: i) under the symmetrical dissemination mechanism, both the assortative and disassorative links can promote the dissemination speed and range of public opinions in a bilayer network. Interestingly, the coupled small-world networks always yield the most effective diffusion;ii) under the asymmetrical dissemination mechanism, the assortative link outperforms the disassortative link on the role of inhabiting public opinion dissemination on online-offline networks. Our findings provide practitioners with theoretical and practical implications of adopting both qualitative and quantitative methods to handle various public opinion disseminations.
