People love to take pictures to represent varied subjects and actions. This gives them the ability to capture what makes them who they are. The advances in technology have led to the explosion of user generated content, and to the problem of better photo mining and retrieval efficacy. Dealing with this problem requires annotating photos with universal tags that are interpretable by other people. In this paper, we propose a better quality tagging machinery for personal pictures that are taken with modern cameras. Our approach annotates photos based on personal actions that are the abstractions that come from events. We use the model of a specific event that is adapted to a particular personal context using all the information and then used for assigning appropriate tags to photos. The model includes the structural aspect of the event because for events, we have sub-events. Ontological event models are used to represent event-subevent-object-place relationships. We present our experiments using 1889 photos in 18 albums.


SETAREH RAFATIRAD is currently a PhD Candidate at the Department of Computer Science at the University of California, Irvine. Her current research is on event-based personal photo annotation, where event ontology and a combination of information sources are used in the solution strategy. Setareh received her Masters degree from UC-Irvine in 2009. During her M.Sc. studies she worked on modeling of events, event relations, composite event operators using event structure, and applying events in the context of semantic computing. Setareh was a recipient of the two-years UC-Irvine School of Information and Computer Science Dean's fellowship. She is a member of the IEEE and the ACM.
