Birds of a Feather Tweet Together: Computational Techniques to Understand User Communities in Social Networks

The study of social systems shows that there is a relationship of mutual influence between social connections and individual behavior, known as homophily. In this work, we developed a methodology to allow the analysis of interests of groups of users in Twitter network, based on automatic community detection and tweets ranking. The techniques presented reveal evidences that the presence of communities is related to topic specialization, and allow the characterization of elaborate profiles of groups of users based only on their location on the network.
