Nigh Amazon Mechanical Turk

What is Amazon Mechanical Turk?

In 1769, Hungarian nobleman Wolfgang von Kempelen astonished Europe by building a mechanical chess-playing automaton that defeated well-nigh every opponent information technology faced. A life-sized wooden mannequin, adorned with a fur-trimmed robe and a turban, Kempelen's "Turk" was seated behind a cabinet and toured Europe, confounding such brilliant challengers as Benjamin Franklin and Napoleon Bonaparte. To persuade skeptical audiences, Kempelen would slide open the cabinet's doors to reveal the intricate set of gears, cogs and springs that powered his invention. He convinced them that he had built a machine that made decisions using artificial intelligence. What they did not know was the hugger-mugger backside the Mechanical Turk: a chess main cleverly concealed inside.

Today, we build circuitous software applications based on the things computers do well, such equally storing and retrieving large amounts of information or rapidly performing calculations. However, humans still significantly outperform the most powerful computers at completing such simple tasks every bit identifying objects in photographs – something children can do even before they larn to speak.

When we recall of interfaces between human beings and computers, we commonly assume that the homo existence is the i requesting that a task exist completed, and the figurer is completing the task and providing the results. What if this process was reversed and a computer program could enquire a man to perform a job and render the results? What if it could coordinate many human being beings to perform a task?

Amazon Mechanical Turk (MTurk) provides a service for service requesters (time to come "Requesters") to integrate Bogus Artificial Intelligence directly into their applications by making requests of humans. Requesters tin can use the MTurk spider web user interface or spider web services API to submit tasks to the MTurk web site, corroborate completed tasks, and incorporate the answers into their applications. When using the web services API, the transaction looks very much like any remote procedure call – the application sends the request, and the service returns the results. In reality, a network of human being Workers (hereafter "Workers") fuels this Artificial Bogus Intelligence past coming to the spider web site, searching for and completing tasks, and receiving reward for their work.

All Requesters need to practise is write normal code. The pseudo code below illustrates how simple this tin exist.

                          read(photo);   photoContainsHuman = callMechanicalTurk(photo);    if (photoContainsHuman == True) {       acceptPhoto();   } else {       rejectPhoto();   }
