What is OpenTurk

OpenTurk is an academic project aimed at improving crowdsourcing platforms both from the worker as well as from the requester point-of-view.

OpenTurk currenlty involves researchers from the University of Fribourg in Switzerland and the University of Sheffield in UK.
The first outcome of this project is the OpenTurk Extension: an open-source tool for MTurk workers to better organize their turking activity.


What OpenTurk does:
  • It wants to make micro-task crowdsourcing more useful and more enjoyable.
  • It stores subscribed requesters and queries to notify workers when new HITs are available.
  • It may use stored data to perform academic research: You can find our resesarch papers here.
What OpenTurk doesn't do:
  • It does not sell or give data to advertisers or third party companies.
  • It does not show advertisements.
  • It does not have a pricing or subscription plan.
