Crowdsourcing, i.e., the provision of micro-tasks to be executed by a large pool of possibly anonymous workers, is attracting an increasing research attention, because it promises to help solving many scientific and practical problems where the harmonic cooperation of humans and machines delivers superior results. This paper proposes a systematic view of the crowdsourcing task design space and categorizes the dimensions that qualify the design decisions in crowdsourcing applications.

Abstract
Crowdsourcing, i.e., the provision of micro-tasks to be executed by a large pool of possibly anonymous workers, is attracting an increasing research attention, because it promises to help solving many scientific and practical problems where the harmonic cooperation of humans and machines delivers superior results. This paper proposes a systematic view of the crowdsourcing task design space and categorizes the dimensions that qualify the design decisions in crowdsourcing applications. For each dimension, we discuss the main open research problems and the most significant contributions, thereby offering guidelines for a principled understanding of current crowdsourcing marketplaces.File | Dimensione | Formato | |
