On November 10 2009 David Ayman Shamma from Yahoo! Research will speak at the Centrum Wiskunde & Informatica about 'A movie and a chat: understanding conversation and real-time video'.

Location: Eulerzaal 
Time      : 14.00 -16.00

People like video. In our homes, at the movies, or cradled in our hands, flickering, glowing screens have the power to draw us in, or at the very least divert our attention. The things we watch spawn conversations. These conversations extend to engage even those who never saw the original program; people learn about recorded events in print, on the web, or from friends.

In this talk, David Ayman Shamma will discuss a range of real-world applications designed to facilitate watching videos while chatting with friends. First, he will discuss a system for synchronized video sharing over Instant Messenger. Next, Ayman will present findings from interviewing several Hip-Hop DJs who live-casted their practice sessions in chat rooms. Finally, he will examine how people use status updates, like on Twitter, while they watch political events on TV. In particular, he will demonstrate methods for segmenting and annotating the media via conversational activity for the purpose of watching the video after the event has already passed. This work is an analysis of the practice of chatting during live events: it details the core metrics that can be used to evaluate and analyze microblogging activity as it relates to watching TV. Finally, he will offer suggestions on how this model of segmentation and node identification could apply towards any live, real-time arbitrary event.
