| Summary: | Microblog is an important social network with rapid propagation speed and great influence.The network influence is determined by users' node characteristic.Nodes' degree and propagation model in microblog forwarding network were investgated.Firstly,microblog forwarding network was constructed through distinguishing information flow direction.Secondly,the mean and variance of out-degree and in-degree were discussed.The difference between out-degree and in-degree was clarified.Finally,the simulation shows that the direction characteristic of edge has significantly influence on information propagation.The propagation becomes harder and propagation range diminishes while percolation threshold rises in directed graph under the same probability. |
