How null-model constraints affect statistical validation in projected bipartite networks
Alessandro Catalano, Rosario N. Mantegna
Statistical validation of projected bipartite networks depends critically on the null model adopted to describe random co-occurrences. Although several null models have been propos…
Two-step estimators of high dimensional correlation matrices
Andrés García-Medina, Salvatore Miccichè, Rosario N. Mantegna
We investigate block diagonal and hierarchical nested stochastic multivariate Gaussian models by studying their sample cross-correlation matrix on high dimensions. By performing nu…
Identifying maximal sets of significantly interacting nodes in higher-order networks
Lorenzo Betti, Federico Musciotto, Federico Battiston +1
Filtering methods are fundamental tools for extracting the backbone of complex networks. Systems displaying group interactions, however, open the way to new types of filtering appr…
Quantifying the relationship between specialisation and reputation in an online platform
Giacomo Livan, Giuseppe Pappalardo, Rosario N. Mantegna
Online platforms experience a tension between decentralisation and incentives to steer user behaviour, which are usually implemented through digital reputation systems. We provide…
Detecting informative higher-order interactions in statistically validated hypergraphs
Federico Musciotto, Federico Battiston, Rosario N. Mantegna
Recent empirical evidence has shown that in many real-world systems, successfully represented as networks, interactions are not limited to dyads, but often involve three or more ag…
Dynamics of fintech terms in news and blogs and specialization of companies of the fintech industry
Fabio Ciulla, Rosario N. Mantegna
We perform a large scale analysis of a list of fintech terms in (i) news and blogs in English language and (ii) professional descriptions of companies operating in many countries.…
