Description
Online labor markets, such as Amazon’s Mechanical Turk, have been used to crowdsource simple, short tasks like image labeling and transcription. However, expert knowledge is often lacking in such markets, making it impossible to complete certain classes of tasks.
This work introduces an alternative mechanism for crowdsourcing tasks that require specialized knowledge or skill: communitysourcing — the use of physical kiosks to elicit work from specific populations. It investigates the potential of communitysourcing by designing, implementing and evaluating Umati: the communitysourcing vending machine.
