Balancing Utility and Fairness in Submodular Maximization (Technical Report)
Yanhao Wang, Yuchen Li, Francesco Bonchi +1
Submodular function maximization is a fundamental combinatorial optimization problem with plenty of applications -- including data summarization, influence maximization, and recomm…
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…
Cascade-based Echo Chamber Detection
Marco Minici, Federico Cinus, Corrado Monti +2
Despite echo chambers in social media have been under considerable scrutiny, general models for their detection and analysis are missing. In this work, we aim to fill this gap by p…
Learning Multiscale Non-stationary Causal Structures
Gabriele D'Acunto, Gianmarco De Francisci Morales, Paolo Bajardi +1
This paper addresses a gap in the current state of the art by providing a solution for modeling causal relationships that evolve over time and occur at different time scales. Speci…
On the Relation Between Opinion Change and Information Consumption on Reddit
Flavio Petruzzellis, Corrado Monti, Gianmarco De Francisci Morales +1
While much attention has been devoted to the causes of opinion change, little is known about its consequences. Our study sheds a light on the relationship between one user's opinio…
On learning agent-based models from data
Corrado Monti, Marco Pangallo, Gianmarco De Francisci Morales +1
Agent-Based Models (ABMs) are used in several fields to study the evolution of complex systems from micro-level assumptions. However, ABMs typically can not estimate agent-specific…
Rewiring What-to-Watch-Next Recommendations to Reduce Radicalization Pathways
Francesco Fabbri, Yanhao Wang, Francesco Bonchi +2
Recommender systems typically suggest to users content similar to what they consumed in the past. If a user happens to be exposed to strongly polarized content, she might subsequen…
FreSCo: Mining Frequent Patterns in Simplicial Complexes
Giulia Preti, Gianmarco De Francisci Morales, Francesco Bonchi
Simplicial complexes are a generalization of graphs that model higher-order relations. In this paper, we introduce simplicial patterns -- that we call simplets -- and generalize th…
