一个社交网络模型

A Model for Social Networks

R. Toivonen, J. -P. Onnela, J. Saramäki, J. Hyvönen, K. Kaski

摘要:

社交网络被组织成具有密集内部连接的社区,从而产生高的聚类系数值。此外,这些网络已经被观察到是互补的,即高度连接的顶点倾向于连接到其他高度连接的顶点,并且具有宽的度分布。我们提出了一个无向增长的网络,再现这些特征的模型,其目的是有效地产生非常大的网络作为研究社会动力学现象的平台。社区是随机依恋和内隐偏好依恋的混合体。该模型的结构特性进行了研究分析和数值,使用$k$ -团的方法来量化的社区。

英文摘要:

Social networks are organized into communities with dense internal connections, giving rise to high values of the clustering coefficient. In addition, these networks have been observed to be assortative, i.e. highly connected vertices tend to connect to other highly connected vertices, and have broad degree distributions. We present a model for an undirected growing network which reproduces these characteristics, with the aim of producing efficiently very large networks to be used as platforms for studying sociodynamic phenomena. The communities arise from a mixture of random attachment and implicit preferential attachment. The structural properties of the model are studied analytically and numerically, using the $k$-clique method for quantifying the communities.
