基于引文网络的无标度网络模型探究

Research On Several Scale-free Network Models And Its Topological Properties

我们提出了几种基于节点失活的无标度复杂网络模型,有些能够很好的解释引文复杂网络中的节点年龄与连接概率负相关性,网络被截断时的无标度性质。而这些性质是用传统BA无标度网络模型所无法解释的。

We study several kinds of scale-free growing network based on a finite memory of the nodes. Some of them shows typical characteristics of citation networks, power-law distribution, a negative correla- tion between the age of a node and its link attachment rate. Moreover, when the real-world network is trun- cated,they also show scale free, which is not accounted by the BA scale free network model.
