CCC Seminar by Jussara M. Almeida, Full Professor of Computer Science at the University of Minas Gerais, Brazil.
Abstract:
This talk examines how information spreads, clusters, and targets specific audiences across social media platforms. Drawing on three empirical studies, I analyze (i) the structure and discourse of misogynistic communities in Brazil, (ii) content directed at children on Instagram, and (iii) the emergence and alignment of political narratives in large-scale Telegram conversations during the 2024 U.S. elections. Together, these findings highlight relevant patterns underlying information diffusion across platforms and raise important questions about exposure, influence, and the amplification of targeted content in online ecosystems.
