Abstract: The rise of social media has offered a fast and easy way for the propagation of fake news and conspiracy theories. Despite the research attention that has received, fake news detection remains an open problem and users keep sharing texts that contain false statements.

In this keynote we will describe how to go beyond textual information to detect fake news. In fact, affective information and visual information need also to be taken into account because providing important insights on how fake news spreaders aim at triggering certain emotions in the readers. We will also see how psycho-linguistic patterns and users' personality traits may play an important role in discriminating fake news spreaders from fact checkers. Finally, we will focus on the role of users in the propagation of conspiracy theories.
