- Abstract:
-
As a widespread social network, the node degree of online social networks has been proven by many researchers to follow the power-law distribution. However, there are few studies modeling the evolution of its structure. In this paper, we propose an evolution model that combines the inside growth, outside growth, and edge replacement based on those of complex networks. The topology properties of this model are analyzed using the mean-field theory. Experiment and theoretical analyses show that the degree of a node in a network generated by the new evolution model follows the power-law distribution and that the power-law index ranges between 1 and 3. Therefore, the proposed model can better reflect the node degree distribution characteristics of different types of real online social networks and will have wide applicability.
