Turing test

A test of artificial intelligence devised by UK mathematician, Alan Turing, who predicted in 1950 that by 2000, a computer could be programmed so that after 5 minutes of questioning, the average interrogator would not have more than a 70% chance of telling whether he or she was talking to a machine or a human. The state of AI has advanced to the degree that for the 2010 Loebner Prize—a platform for Turing Tests—the interaction time was increased to 25 minutes.
