The social computing group is developing computational methods for processing and analyzing large scale social data, aiming to understanding complex social behavior and to inform the design of human-centered and socially aware systems. In recent research we studied the emergence of conventions in Twitter, we developed methods for preventing spam in social networks, and we proposed a framework for tracking the relation between a user and its community.
