A game theoretical model of information dissemination in social network

Abstract

This paper puts forward an information dissemination model on social network. A framework is presented to understand human impacts on information dissemination, which are generalized as a utility function, several factors shaping human behavior are involved, such as knowledge, belief, persuasion, memory and reputation. Each individual in the network is considered as either sender or receiver, who plays differently taking into account their payoffs, and information can spread through the underlying network in the form of comments and forwarding. Several cases were analyzed, and the results show that information dissemination can be divided into several stages, besides, the speed of spreading is influenced by characteristic of individuals in the network.
