Modeling and Analysis of Information Propagation Model of Online/Offline Network Based on Coupled Network

Abstract

Currently, more and more scholars believe that most networks are not isolated, but interact with each other. Internet-based social network (online network), and physical contact networks (offline network) are a coupled network that interact with each other. Person have online virtual identity and offline social identity. In this paper, the double SIR information spreading model with unilateral effect is constructed according to the characteristics of online and offline information dissemination. And two typical types of coupled networks, BA_BA network and WS_WS network, are used to simulate. The experimental results show that the online information propagation can inhibit the scope of offline. This inhibition is slightly weaker for the BA_BA network that the inter degree-degree correlation (IDDC) is positive. At the same time, it is found that the increase of the interlayer influence rate can enhance the synchronization of information transmission on online and offline so that effectively promote the information propagation of online/offline.
