Amazon Mechanical Turk is an online marketplace that enables businesses to outsource tasks to a global, on-demand workforce. With Mechanical Turk, businesses can access a large pool of qualified workers to complete tasks that are difficult to automate, such as image recognition, transcription, and data collection. Business
Amazon Mechanical Turk (MTurk) is a crowdsourcing website with which businesses can hire remotely located "crowdworkers" to perform discrete on-demand tasks that computers are currently unable to do as economically. It is operated under Amazon Web Services, and is owned by Amazon. Employers, known as requesters, post jobs known as Human Intelligence Tasks (HITs), such as identifying specific content in an image or video, writing product descriptions, or answering survey questions. Workers, colloquially known as Turkers or crowdworkers, browse among existing jobs and complete them in exchange for a fee set by the requester. To place jobs, requesters use an open application programming interface (API), or the more limited MTurk Requester site. As of April 2019, requesters could register from 49 approved countries. It is named after the Mechanical Turk, a chess machine.
