Abstract: Social network is an important carrier of information diffusion, and social tie is one of most significant factors between them. To understand the impact of social tie on information dissemination, a dynamical model with social tie strength and self-confirming mechanism is proposed and analyzed in this paper. Theoretical analysis indicates that the equilibrium of the proposed model is globally asymptotically stable, and social tie plays a key role in information propagation. Finally, some numerical simulations under synthetic networks and a partial Facebook network are given to illustrate the main results.
