Semi-Monotonicity for Spectral Centrality Measures
Paolo Boldi, Davide D'Ascenzo, Flavio Furia +1
Score monotonicity and rank monotonicity are properties describing the behavior of a centrality measure when an arc is added to a network: the former requires that the score of the…
Recognizing Distance-Count Matrices is Difficult
Paolo Boldi, Flavio Furia, Chiara Prezioso +1
Axiomatization of centrality measures often involves proving that something cannot hold by providing a counterexample (i.e., a graph for which that specific centrality index fails…
Properties and Expressivity of Linear Geometric Centralities
Paolo Boldi, Flavio Furia, Chiara Prezioso
Centrality indices are used to rank the nodes of a graph by importance: this is a common need in many concrete situations (social networks, citation networks, web graphs, for insta…
Score and Rank Semi-Monotonicity for Closeness, Betweenness and Harmonic Centrality
Paolo Boldi, Davide D'Ascenzo, Flavio Furia +1
In the study of the behavior of centrality measures with respect to network modifications, score monotonicity means that adding an arc increases the centrality score of the target…
Monotonicity in Undirected Networks
Paolo Boldi, Flavio Furia, Sebastiano Vigna
Is it always beneficial to create a new relationship (have a new follower/friend) in a social network? This question can be formally stated as a property of the centrality measure…
Spectral Rank Monotonicity on Undirected Networks
Paolo Boldi, Flavio Furia, Sebastiano Vigna
We study the problem of score and rank monotonicity for spectral ranking methods, such as eigenvector centrality and PageRank, in the case of undirected networks. Score monotonicit…
