Abstract

The development of social networks has enabled the collection of behavioral data of unprecedented size and complexity. Modern social platforms have realized that great scientific and marketing values are contained in the millions of billions of behavioral records. How can we model users' behaviors in social networks? What are the concepts and principles in modeling the complex behaviors? Can we develop efficient models for accurate behavior prediction and detection in social applications such as recommender systems, personalized search and social marketing? In this tutorial, we answer these questions by uncovering the social and spatiotemporal contextual dependency, cross-domain and cross-platform properties, synchronized and abnormal characteristics, and many other patterns of users' behaviors. We introduce recent advances in modeling complex behaviors from the perspectives of individuals, groups and cascades (from micro to macro) in social networks. Finally we summarize the tutorial with discussions on open issues and challenges about behavior modeling in social networks.
