This line addresses challenges related to misinformation, hate speech, and polarization, proposing computational and social solutions to strengthen the quality of information systems and promote a more balanced understanding of reality.

The approach combines computer science, communication science, and political science, integrating mixed methods for the analysis of digital phenomena and developing new methodologies for processing large volumes of data.

His research areas include: studying the emergence and spread of misinformation, analyzing uncivil conversation on digital platforms, and developing computational tools to improve robustness, explainability, and control in recommendation systems, natural language processing, and semantic representation.

Magdalena Saldaña, professor at the Faculty of Communications at the Pontifical Catholic University of Chile, together with Sebastián Valenzuela, professor at the Faculty of Communications at the Pontifical Catholic University of Chile, are the leaders of this line of research, which also includes Benjamín Bustos (Department of Computer Science at the University of Chile), Bárbara Poblete (Department of Computer Science, University of Chile), Denis Parra ( Department of Computer Science, Pontifical Catholic University of Chile), Felipe Bravo-Marquez(Department of Computer Science, University of Chile), and Ricardo Baeza-Yates(Department of Computer Science, University of Chile).
