Abstract

The paradigm of seeks to harness human abilities to solve computational problems or otherwise perform distributed work that is beyond the scope of current AI technologies. One aspect of human computation has become known as games with a purpose and seeks to elicit useful computational work in fun (typically) multi-player games. Human computation also encompasses distributed work (or peer production) systems such as Wikipedia and Question and Answer forums. In this short paper, we survey existing game-theoretic models for various human computation designs, and outline research challenges in advancing a theory that can enable better design.

Highlights

  • Over the last few years, there has been a great deal of progress in human computation and “Games with a Purpose” (GWAP)

  • We believe that game theory has considerable promise in guiding the design of human computation systems when coupled with an appropriate model of human motivations

  • There are a number of exciting directions for future work examining the role of game theory in formalizing the design of human computation systems, where incentives are a firstorder consideration

Summary

INTRODUCTION

Over the last few years, there has been a great deal of progress in human computation and “Games with a Purpose” (GWAP) As of yet, this field has not borrowed much from game theory and mechanism design, which models the behavior of rational agents in situations of strategic interdependence and designs optimal protocols given such a model, respectively. GWAP fit into the larger realm of peer production and systems to elicit user-generated content. Examples of such systems are Wikipedia, Question and Answer sites Human computation more broadly, in encompassing peer production and other systems, resembles the salient aspects of P2P file sharing problems in regard to opportunity for free-riding and the need to promote user contribution
