Online social platforms (OSPs), such as Facebook, Twitter, and Instagram, have grown monumentally over recent years. It was reported that as of August 2017, Facebook has over 2 billion monthly active users, while Instagram and Twitter have over 700 million and 300 million monthly active user accounts respectively. The vast amount of user-generated content and social data gathered in these behemoth platforms have made them rich data sources for academic and industrial research. However many of the existing research work has focused on analyzing and modeling users behaviors in a single platform setting, neglecting the inter-dependencies of user behaviors across multiple OSPs. In this sharing, I will present our recent work on analyzing and modeling user behaviors in multiple OSPs. In particular, I will focus on (i) analyzing users’ topical interests and platform preferences across multiple OSPs, and (ii) modeling influential users in multiple OSPs
