Title: Generalized Rich-Club Ordering in Networks

Abstract: Rich-club ordering refers to tendency of nodes with a high degree to be more interconnected than expected. In this paper we consider the concept of rich-club ordering when generalized to structural measures different from the node degree and to non-structural measures (i.e. to node metadata). The differences in considering rich-club ordering (RCO) with respect to both structural and non-structural measures is then discussed in terms of employed coefficients and of appropriate null models (link rewiring vs metadata reshuffling). Once defined a framework for the evaluation of generalized rich-club ordering (GRCO), we investigate such a phenomenon in real networks provided with node metadata. By considering different notions of node richness we compare structural and non-structural rich-club ordering, observing how external information about the network nodes is able to validate the presence of elites in networked systems.
