The ever-growing social media and mobile computing platforms provide invaluable sources of information for modeling the behavior of users. High-quality user models enable superior services and functions for end users. In this talk, I will present several examples of user modeling based on social networks and social media. I will first describe our research in modeling users' information preferences on Microblogs using a novel user message model. I will then discuss our work on extracting users' daily activities, such as dining and shopping, that inherently reflect their habits, intents and preferences. I explain our novel transfer learning solution via a collaborative boosting framework comprising a text-to-activity classifier for socially connected users. I will also discuss our work on modeling the user behavior in mobile computing environments for building context-aware and adaptive information agents. The video of his talk can be watched here.
