Emerging theories and models of human computation systems: A brief survey

The ubiquitous access to computing systems has spurred the design of a variety of human computation systems, each aiming to harness the power of human computation to tackle problems that cannot be solved by today's computers alone. However, the rapid pace of progress in developing increasingly complex human computation systems has far outstripped the development of abstract models to evaluate, compare and generalize such systems. In this paper we present a brief thematic overview of the nascent theories and models of human computing systems by grouping them along key design choices in building such systems. © 2011 ACM.
