Amazon Mechanical Turk

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.[1] 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 employer. To place jobs, the requesting programs^{[clarification needed]} use an open application programming interface (API), or the more limited MTurk Requester site.[2] As of April 2019^[update], Requesters could register from 49 approved countries.[3]
