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…
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…
Liquid FM: Recommending Music through Viscous Democracy
Paolo Boldi, Corrado Monti, Massimo Santini +1
Most modern recommendation systems use the approach of collaborative filtering: users that are believed to behave alike are used to produce recommendations. In this work we describ…
Interactions of cultures and top people of Wikipedia from ranking of 24 language editions
Young-Ho Eom, Pablo Aragón, David Laniado +3
Wikipedia is a huge global repository of human knowledge, that can be leveraged to investigate interwinements between cultures. With this aim, we apply methods of Markov chains and…
