"Let's share a story": Socially-enhanced multimedia storytelling

User generated audio-visual content is becoming the most popular medium for information sharing and social storytelling around a live event. This paper introduces an online multimedia storytelling eco-system comprised of purpose-built user applications, collaborative story authoring engine, social context integration, and social-aware media services. The system enables online collaborative story co-authoring and provides an ideal platform to study the synergy between social networks and networked media in enhancing the user experience of storytelling as highlighted in our event-based user experiments.
