Giulia Preti, Matteo Riondato, Aristides Gionis +1
Social and information networks may become polarized, leading to echo chambers and political gridlock. Accurately measuring this phenomenon is a critical challenge. Existing measur…
Alice and the Caterpillar: A more descriptive null model for assessing data mining results
Giulia Preti, Gianmarco De Francisci Morales, Matteo Riondato
We introduce novel null models for assessing the results obtained from observed binary transactional and sequence datasets, using statistical hypothesis testing. Our null models ma…
Polaris: Sampling from the Multigraph Configuration Model with Prescribed Color Assortativity
Giulia Preti, Matteo Riondato, Aristides Gionis +1
We introduce Polaris, a network null model for colored multi-graphs that preserves the Joint Color Matrix. Polaris is specifically designed for studying network polarization, where…
Measuring Online Behavior Change with Observational Studies: a Review
Arianna Pera, Gianmarco de Francisci Morales, Luca Maria Aiello
Exploring online behavior change is imperative for societal progress in the context of 21st-century challenges. We analyze 148 articles (2000-2023) focusing on behavior change in t…
An impossibility result for Markov Chain Monte Carlo sampling from micro-canonical bipartite graph ensembles
Giulia Preti, Gianmarco De Francisci Morales, Matteo Riondato
Markov Chain Monte Carlo (MCMC) algorithms are commonly used to sample from graph ensembles. Two graphs are neighbors in the state space if one can be obtained from the other with…
The language of opinion change on social media under the lens of communicative action
Corrado Monti, Luca Maria Aiello, Gianmarco De Francisci Morales +1
Which messages are more effective at inducing a change of opinion in the listener? We approach this question within the frame of Habermas' theory of communicative action, which pos…
