In 1950 Alan Turing proposed what would later be known as the Turing test in a paper he published. This paper proposed that a computer must display enough intelligence to convince a jury that it is, in fact, human. This can be tested by having a conversation through the computer with the judges at the competition. At this point, minimum 30% of the judges have to be convinced that behind the computer there might actually be a real person.
