Higher order assortativity for directed weighted networks and Markov chains
Alberto Arcagni, Roy Cerqueti, Rosanna Grassi
This paper proposes a new class of assortativity measures for weighted and directed networks. We extend the classical Newman's degree-degree assortativity by considering nodes' att…
Taxonomy of Cohesion Coefficients for Weighted and Directed Multilayer Networks
Paolo Bartesaghi, Gian Paolo Clemente, Rosanna Grassi
Clustering and closure coefficients are among the most widely applied indicators in the description of the topological structure of a network. Many distinct definitions have been p…
A tensor-based unified approach for clustering coefficients in financial multiplex networks
Paolo Bartesaghi, Gian Paolo Clemente, Rosanna Grassi
Big data and the use of advanced technologies are relevant topics in the financial market. In this context, complex networks became extremely useful in describing the structure of…
Community structure in the World Trade Network based on communicability distances
Paolo Bartesaghi, Gian Paolo Clemente, Rosanna Grassi
In this paper, we investigate the mesoscale structure of the World Trade Network. In this framework, a specific role is assumed by short and long-range interactions, and hence by t…
Multi-attribute community detection in International Trade Network
Paolo Bartesaghi, Stefano Benati, Gian Paolo Clemente +1
Understanding the structure of communities in a network has a great importance in the economic analysis. Communities are indeed characterized by specific properties, that are diffe…
Influence measures in subnetworks using vertex centrality
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
Roy Cerqueti, Gian Paolo Clemente, Rosanna Grassi
This paper presents a new definition of the community structure of a network, which takes also into account how communities are stratified. In particular, we extend the standard co…
Systemic risk assessment through high order clustering coefficient
Roy Cerqueti, Gian Paolo Clemente, Rosanna Grassi
In this article we propose a novel measure of systemic risk in the context of financial networks. To this aim, we provide a definition of systemic risk which is based on the struct…
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…
Higher order assortativity in complex networks
Alberto Arcagni, Rosanna Grassi, Silvana Stefani +1
Assortativity was first introduced by Newman and has been extensively studied and applied to many real world networked systems since then. Assortativity is a graph metrics and desc…
