Output Agreement Mechanisms and Common Knowledge
Proceedings of the AAAI Conference on Human Computation and Crowdsourcing
The recent advent of human computation -- employing non-experts to solve problems -- has inspired theoretical work in mechanism design for eliciting information when responses cannot be verified. We study a popular practical method, output agreement, from a theoretical perspective. In output agreement, two agents are given the same inputs and asked to produce some output; they are scored based on how closely their responses agree. Although simple, output agreement raises new conceptualdoi:10.1609/hcomp.v2i1.13151 fatcat:ji5ysjtopnc4npmpjtt3rfzcqu
