Human Computation

Edith Law is a Ph.D. candidate at Carnegie Mellon University, who is doing research on human computation systems that harness the joint efforts of machines and humans, with a focus on games with a purpose and citizen science. She is the co-organizers of the 1st and 3rd human computation workshops (HCOMP2009 andHCOMP2011), and the recipient of Microsoft Graduate Research Fellowship 2009-2011. Her work on TagATune has received a best paper nomination at CHI 2009.Luis von Ahn is the A. Nico Habermann Associate Professor in the Computer Science Department at Carnegie Mellon University. His current research interests include building systems that combine the intelligence of humans and computers to solve large-scale problems that neither can solve alone. An example of his work is reCAPTCHA, in which over 750 million people—more than 10% of humanity—have helped digitize books and newspapers. He is the recipient of a MacArthur Fellowship, a Packard Fellowship, a Microsoft New Faculty Fellowship, and a Sloan Research Fellowship. He has been named one of the 50 Best Minds in Science by Discover Magazine, one of the 100 Most Creative People in Business of 2010 by Fast Company Magazine, and one of the “Brilliant 10" scientists of 2006 by Popular Science Magazine.
