A taxonomy of microtasks on the web
Ujwal Gadiraju, Ricardo Kawase, Stefan Dietze · 2014
Nowadays, a substantial number of people are turning to crowdsourcing, in order to solve tasks that require human intervention. Despite a considerable amount of research done in the field of crowdsourcing, existing works fall short when it comes to classifying typically crowdsourced tasks. Understanding the dynamics of the tasks that are crowdsourced and the behaviour of workers, plays a vital role in efficient task-design. In this paper, we propose a two-level categorization scheme for tasks, based on an extensive study of 1000 workers on CrowdFlower. In addition, we present insights into certain aspects of crowd behaviour; the task affinity of workers, effort exerted by workers to complete tasks of various types, and their satisfaction with the monetary incentives.
