Abstract

Online social network services (SNS) have been experiencing rapid growth in recent years. Discovering densely connected user communities from social networks has become a major challenge, with important implications in understanding the structural properties of SNS and improving user-oriented services. Previous work on community discovery has treated user friendship networks and user-generated contents separately. We hypothesize that these two types of information can be fruitfully integrated and propose a unified framework for this task by combining the author-topic model with user friendship network analysis. We empirically show that our approach is capable of discovering interesting user communities using two real-world datasets.
