Abstract: In this paper, we present our efforts towards creating interfaces for networked media exploration and collaborative annotation. The problem is important since online social networks are emerging as conduits for exchange of everyday experiences. These networks do not currently provide media-rich communication environments. Our approach has two parts – collaborative annotation, and a media exploration framework. The collaborative annotation takes place through a web based interface, and provides to each user personalized recommendations, based on media features, and by using a common sense inference toolkit. We develop three media exploration interfaces that allow for two-way interaction amongst the participants – (a) spatio-temporal evolution, (b) event cones and (c) viewpoint centric interaction. We also analyze the user activity to determine important people and events, for each user. We also develop subtle visual interface cues for activity feedback. Preliminary user studies indicate that the system performs well and is well liked by the users.
