Title:<\/strong> Understanding and Modeling Collective User (Mis-)Behavior Driving Information Spread Online<\/p>\n\n\n\n

Abstract<\/strong><\/p>\n\n\n\n

The literature is quite rich in efforts to model and analyze how different aspects of user behavior may drive the dissemination of a
piece of content online, favoring its spread at large. Yet, human behavior is often very heterogeneous, highly dynamic, and may manifest
itself in multiple facets and scales, with components that are conceptually hard to operationalize. As such, inferring behavioral
patterns and profiles from digital traces can be quite challenging. In this talk, I will discuss our efforts towards inferring, modeling and
analyzing collective user behavior (notably user campaigns) towards favoring information dissemination online. I will show results applied
to the study of spread of fake news, illegal political ads, and hate speech. Finally, as a short detour, I will discuss recent results on the
use of similar techniques to a completely different context, namely scientometrics, to analyze the emergence of anomalous hyperprolific
researchers.<\/p>\n\n\n\n
