The Turing Test is a method of evaluating a machine's ability to exhibit human-like intelligence. It involves a human judge engaging in a text-based conversation with both a human and a machine, and then deciding which of the two is human. If the judge is unable to distinguish between the human and the machine based on the conversation, the machine is said to have passed the Turing Test. This test was first proposed by Alan Turing in 1950 and is widely used as a benchmark for measuring the success of artificial intelligence (AI) research.
