Roy Cerqueti, Gian Paolo Clemente, Rosanna Grassi
This work deals with the issue of assessing the influence of a node in the entire network and in the subnetwork to which it belongs as well, adapting the classical idea of vertex c…
Stratified communities in complex business networks

Directed clustering in weighted networks: a new perspective
Gian Paolo Clemente, Rosanna Grassi
In this paper, we consider the problem of assessing local clustering in complex networks. Various definitions for this measure have been proposed for the cases of networks having w…
