Social Network based community Users´ Viscosity enhanced model

Users´ Viscosity is the key to the success of community application, how to improve the Users´ Viscosity as much as possible is the challenge that researchers have to face. In the paper, we propose a Social Network based community Users´ Viscosity enhanced model. In the model we divide the big social network into small social networks and introduce the competition mechanism among them, the number of members, the degree of Activity and Contribution of them is used to compute the live value of the small social network. Simulating experiments prove that the model can make the small social networks become more prosperous, thus it can improve the viscosity of community users.
