Abstract：Online Social Networking (OSN) is a complex system, where both users and messages are fundamental objects when investigating the network topology and the disseminations of information. To study the structure features and the rules of information propagation, this paper analyzes about 30,000 users including their friendships and the most recent 200 posts. The main statistical results include: 1) SINA network is not dense and the correlation density is almost linear; 2) during the dissemination of a single post, “10-90 rule” occurs, that is to say 10% of the users can affect the other 90%; and 3) four patterns can be concluded considering both life-cycle and forwarding structure. These results may provide the basis for subsequent modeling, as well as benefition the public opinion monitoring and cyber marketing.
