ACMKDD Human Computation (HCOMP2010) We invite you to participate in HCOMP2010 which will be held with KDD in Washington, DC, USA on July 25, 2010. Human computation is a relatively new research area that studies the process of channeling the vast internet population to perform tasks or provide data towards solving difficult problems that no known efficient computer algorithms can yet solve. HComp 2010 is to bring together academic and industry researchers in a stimulating discussion of existing human computation applications and future directions of this area. Topics of interests include, but are not limited to: • Abstraction of human computation tasks into taxonomies of mechanisms • Programming languages, tools and platforms to support human computation • Domain-specific implementation challenges in human computation games • Cost, reliability, and skill of labelers • Benefits of one-time versus repeated labeling • Game-theoretic mechanism design of incentives for motivation and honest reporting • Design of manipulation-resistance mechanisms in human computation • Active learning from imperfect human labelers • Utility of social networks and social credit in garnering data • Optimality in the context of human computation • Focus on tasks where crowds, not individuals, have the answers • Limitations of human computation The program for HCOMP2010 can be found at http://hcomp.info/HComp2010/index.html Registration information is available through http://www.kdd.org/kdd2010/registration.shtml
