A Model of Diffusion Parameter Characterizing Social Networks
نویسندگان
چکیده
We introduce a new diffusion property to characterize different models of social networks; the “Degree of Diffusion α ”. The degree of diffusion α introduced in this work is a totally new parameter. It relates the ratio of adopters over the non-adopters to the penetration depth in a diffusion process over a social network. It predicts the future possible adopters within any diffusion process. Each social network model is found to have a different diffusion characteristic value: Random α =148, Small-World α =4.56 and Scale-Free α =1.50. A case study of a Real Social Network (Virtual Friendship Network) is found to have a value of α =29.58 which characterizes the network to be between Random and a Small-World network models.

In this paper we study the topology effects on diffusion process in signed networks. Considering a simple threshold model for diffusion process, it is extended to signed networks and some appropriate definitions are proposed. This model is a basic model that could be extended and applied in analyzing dynamics of many real phenomena such as opinion forming or innovation diffusion in social netwo...
