Welcome

Amazon Mechanical Turk is human intelligence in a web service. Amazon Mechanical Turk can give you an opinion, or thousands of opinions. It can provide an intuitive judgement about a set of facts. It can perform research and give additional information about your data. With Amazon Mechanical Turk, your application can ask questions that only a human being can answer, using a web services interface.

Amazon Mechanical Turk posts your application's questions to the Amazon Mechanical Turk web site, where they are found and answered by Amazon Mechanical Turk users. Your application then retrieves the answers using the web service. From your application's perspective, Amazon Mechanical Turk behaves like any other asynchronous web service: Your application submits the request using a programmatic interface, then retrieves the result of that request from the service at a later time.

The following documentation describes how to use the Amazon Mechanical Turk web service.
