Presentation at Yahoo! Research on user-contributed content

Yahoo! Research invited me to speak in their “Big Thinkers” series at the Santa Clara campus on 12 March 2008. My talk was “Incentive-centered design for user-contributed content: Getting the good stuff in, Keeping the bad stuff out.”
My hosts wrote a summary of the talk (that is a bit incorrect in places and skips some of the main points, but is reasonably good), and posted a video they took of the talk. The video, unfortunately, focuses mostly on me without my visual presentation, panning only occasionally to show a handful of the 140 or so illustrations I used. The talk is, I think, much more effective with the visual component. (In particular, it reduces the impact of the amount of time I spend glancing down to check my speaker notes!)
In the talk I present a three-part story: UCC problems are unavoidably ICD problems; ICD offers a principled approach to design; and ICD works in practical settings. I described three main incentives challenges for UCC design: getting people to contribute; motivating quality and variety of contributions; and discouraging “polluters” from using the UCC platform as an opportunity to publish off-topic content (such as commercial ads, or spam). I illustrated with a number of examples in the wild, and a number of emerging research projects on which my students and I are working.
