大型移动电话呼叫网统计特性的比较分析
A comparative analysis of the statistical properties of large mobile phone calling networks
摘要：
手机通话是现代社会中使用最广泛的通信方式之一。手机用户之间的通话记录为我们了解社交网络中的人类交流模式提供了一个有价值的代理。移动电话用户相互呼叫，形成有向呼叫网络。如果只考虑相互呼叫，我们得到一个无向相互呼叫网络。两个连接的用户之间的优先通信行为可以进行统计测试，它导致两个Bonferroni网络具有统计验证的边缘。我们对这四个网络的统计特性进行了比较分析，这四个网络是由上海900多万人在110天内的通话记录构建的。我们发现，这些网络有许多共同的结构特性，也表现出特质的功能相比，以前研究的大型移动电话网络。实证研究结果为我们提供了一个有趣的图片，一个有代表性的大型社交网络，可能会揭示新的光大型社交网络的建模。
英文摘要：
Mobile phone calling is one of the most widely used communication methods in modern society. The records of calls among mobile phone users provide us a valuable proxy for the understanding of human communication patterns embedded in social networks. Mobile phone users call each other forming a directed calling network. If only reciprocal calls are considered, we obtain an undirected mutual calling network. The preferential communication behavior between two connected users can be statistically tested and it results in two Bonferroni networks with statistically validated edges. We perform a comparative analysis of the statistical properties of these four networks, which are constructed from the calling records of more than nine million individuals in Shanghai over a period of 110 days. We find that these networks share many common structural properties and also exhibit idiosyncratic features when compared with previously studied large mobile calling networks. The empirical findings provide us an intriguing picture of a representative large social network that might shed new lights on the modelling of large social networks.
