For many complex networks present in nature only a single instance, usually of large size, is available. Any measurement made
on this single instance cannot be repeated on different realizations. In order to detect significant patterns in a real-world
network it is therefore crucial to compare the measured results with a null model counterpart. Here we focus on dense and
weighted networks, proposing a suitable null model and studying the behaviour of the degree correlations as measured by the
rich-club coefficient. Our method solves an existing problem with the randomization of dense unweighted graphs, and at the
same time represents a generalization of the rich-club coefficient to weighted networks which is complementary to other recently
proposed ones. 相似文献
