Modeling of Posting Behavior in Mobile Internet Based on Human Dynamcis

With rapid development of information and communication technology, human behavior has extended to mobile internet. In this paper, we studied posting behavior of micro-blog users in mobile internet. Statistical results suggest that there exist significant negative correlation between inter-event time and social concern. This means that users´ interest in posting micro-blogs is influenced by social concern. Then, we proposed an interest-driven model including social concern mechanism. The numerical simulation of the model fits well with the analytical solution. The model was further generalized through considering the probability of obtaining social concern. By quantifying parameters according to the real data, it can reproduce an inter-event time distribution with power law and fat tail features, which is in good agreement with empirical result.
