校正重叠权重和聚类系数

Corrected overlap weight and clustering coefficient

Vladimir Batagelj

摘要:

我们讨论了两个著名的网络措施:一个边缘的重叠权重和一个节点的聚类系数。对于这两种情况,事实证明,它们对于识别给定网络的重要元素(节点或链接)的数据分析任务都不是很有用。其原因是,它们在相对较小的最大子图上获得最大值,这些最大子图比较大的最大子图更有可能出现在网络中。我们展示了如何这些措施的定义可以纠正这样一种方式,他们给预期的结果。我们说明了拟议的纠正措施,将它们应用于美国机场网络使用程序Pajek。

英文摘要:

We discuss two well known network measures: the overlap weight of an edge and the clustering coefficient of a node. For both of them it turns out that they are not very useful for data analytic task to identify important elements (nodes or links) of a given network. The reason for this is that they attain their largest values on maximal subgraphs of relatively small size that are more probable to appear in a network than that of larger size. We show how the definitions of these measures can be corrected in such a way that they give the expected results. We illustrate the proposed corrected measures by applying them on the US Airports network using the program Pajek.
