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…
Estimating latent feature-feature interactions in large feature-rich graphs
Corrado Monti, Paolo Boldi
Real-world complex networks describe connections between objects; in reality, those objects are often endowed with some kind of features. How does the presence or absence of such f…
LlamaFur: Learning Latent Category Matrix to Find Unexpected Relations in Wikipedia
Paolo Boldi, Corrado Monti
Besides finding trends and unveiling typical patterns, modern information retrieval is increasingly more interested in the discovery of surprising information in textual datasets.…
