Over the past decade, multimedia social networks (MSNs) have explosively spread into every aspect of our lives, thanks to mobile Internet and terminals. This paper extends the SocialSitu framework and proposes a novel algorithm for analyzing user intentions using Generalized Sequential Patterns. It analyzed user behaviors to predict intentions, specifically focusing on playing and sharing multimedia in MSNs. User behavior patterns vary with identity in different sessions.
