Ein sehr interessanter und darüber hinaus ungemein unterhaltsamer (!) Talk von Luis von Ahn über Human Computation, der zeigt, wie Computerspiele dazu eingesetzt werden können, um Probleme zu lösen, die Computer nicht lösen können - zum Beispiel Tagging von Content im Web. Ein sehr interessanter Ansatz, wie Spiele eingesetzt werden können um einen (den Spielern nicht bekannten) Nutzen daraus zu ziehen - die Generation von Daten (z.B. eben Tags). Ein sehr interessanter Ansatz.

Human Computation
Google TechTalks July 26, 2006

Luis von Ahn is an assistant professor in the Computer Science
Department at Carnegie Mellon University, *. *where he also received his
Ph.D. in 2005. Previously, Luis obtained a B.S. in mathematics from Duke
University in 2000. He is the recipient of a Microsoft Research Fellowship.

ABSTRACT Tasks like image recognition are trivial for humans, but
continue to challenge even the most sophisticated computer programs.
This talk introduces a paradigm for utilizing human processing power to
solve problems that computers cannot yet solve. Traditional approaches
to solving such problems focus on improving software. I advocate a novel
approach: constructively channel human brainpower using computer games.
For example, the ESP Game, described in this talk, is an enjoyable
online game -- many people play over 40 hours a week -- and when people
play, they help label images on the Web with descriptive keywords. These
keywords can be used to significantly improve the accuracy of image
search. People play the game not because they want to help, but because
they enjoy it.

I describe other examples of "games with a purpose": Peekaboom, which
helps determine the location of objects in images, and Verbosity, which
collects common-sense knowledge. I also explain a general approach for
constructing games with a purpose.
