摘要
提出一个具有集团性质的合作网络模型,其演化机制不仅包含新演员与集团内的演员合作,还包含新演员与集团外的演员之间的合作.根据主方程方法和平均场方法,证明了该模型生成的演员合作投影网络的度分布具有幂律尾部,演员参与电影数量的概率分布律也具有幂律尾部.该网络呈现无标度特征.
In present paper,a model of collaboration network with community structure is proposed,there are the collaborations of new actors and actors in the same community,and new actors and actors in another community.By the master-equation approach and the mean-field method,the degree distribution of a actor has a power-law tail.The network presents a scale-free character.
