社交网络的结构性质及其度量校准合成对应物

On the Structural Properties of Social Networks and their Measurement-calibrated Synthetic Counterparts

Marcell Nagy, Roland Molontay

摘要:

大型社交网络的数据驱动分析吸引了大量的研究兴趣。在本文中,我们调查了120个真实的社交网络和他们的测量校准合成对应的四个著名的网络模型。我们研究了网络的结构特性,揭示了各种社会领域(友谊网络,通信网络和协作网络)的图度量的相关性。我们发现,不同领域的相关模式不同。我们确定了一个非冗余的一组指标来描述社交网络。我们研究的模型可以或不能捕获的真实网络的拓扑特征。我们发现,网络模型的拟合优度依赖于域。此外,虽然2K和随机块模型缺乏同时生成具有大直径和高聚类系数的图的能力,但它们仍然可以用于相对有效地模拟社交网络。

英文摘要:

Data-driven analysis of large social networks has attracted a great deal of research interest. In this paper, we investigate 120 real social networks and their measurement-calibrated synthetic counterparts generated by four well-known network models. We investigate the structural properties of the networks revealing the correlation profiles of graph metrics across various social domains (friendship networks, communication networks, and collaboration networks). We find that the correlation patterns differ across domains. We identify a non-redundant set of metrics to describe social networks. We study which topological characteristics of real networks the models can or cannot capture. We find that the goodness-of-fit of the network models depends on the domains. Furthermore, while 2K and stochastic block models lack the capability of generating graphs with large diameter and high clustering coefficient at the same time, they can still be used to mimic social networks relatively efficiently.
