Turing test

test defined by the mathematician Allen Turing for testing the ability of a machine to simulate human intelligence

For the Doctor Who novel named after the test, see The Turing Test (novel). For the opera named after the test, see under the composer, Julian Wagstaff.The Turing test is a proposal for a test of a machine's capability to demonstrate intelligence. Described by Professor Alan Turing in the 1950 paper "Computing machinery and intelligence," it proceeds as follows: a human judge engages in a natural language conversation with one human and one machine, each of which try to appear human; if the judge cannot reliably tell which is which, then the machine is said to pass the test. In order to keep the test setting simple and universal (to explicitly test the linguistic capability of the machine instead of its ability to render words into audio), the conversation is usually limited to a text-only channel such as a teletype machine as Turing suggested or, more recently, IRC or instant messaging.

<artificial intelligence> A criterion proposed by Alan Turing in 1950 for deciding whether a computer is intelligent. Turing called it "the Imitation Game" and offered it as a replacement for the question, "Can machines think?"
A human holds a written conversation on any topic with an unseen correspondent (nowadays it might be by electronic mail or chat). If the human believes he is talking to another human when he is really talking to a computer then the computer has passed the Turing test and is deemed to be intelligent.
Turing predicted that within 50 years (by the year 2000) technological progress would produce computing machines with a capacity of 10**9 bits, and that with such machinery, a computer program would be able to fool the average questioner for 5 minutes about 70% of the time.
The Loebner Prize is a competition to find a computer program which can pass an unrestricted Turing test.
Julia is a program that attempts to pass the Turing test.
