Because a computer is limited - by the database of words it has stored on its hard-drive. The human brain is far more complex - able to form complex sentences at will. Also - a computer cannot contract words (such as can not into can't) as a human would - because it is unable to decide whether the sentence still makes sense with the contraction.
The turing test is a test to tell the difference between humans and computers. It works likes this: * A person (A) asks questions * Another person (B) answers * A computer (C) answers as well * If A can not tell which one (B or C) is the computer the computer has passed and is artificially intelligence, to find out more got to wikipedia.org and search for turing test.
No, it measures a computer's similarity to human intelligence. If it can make an answer to a random question and sound human, then it's passed.
Turing test
No. See the related links section for a link to the Loebner Prize website, which awards $5,000 annually for the chatbot which is "most indistinguishable from a human." There is still $100,000 reserved from Dr. Loebner for the first chatbot to actually pass the Turing test.
The purpose of a Turing test is to determine a machine's ability to exhibit intelligent behavior that is indistinguishable from that of a human. It tests whether a machine can successfully imitate a human to the extent that another human interacting with it cannot differentiate between the two.
It's a test - of a machine's capability to mimic human behaviour so precisely - that it is impossible to distinguish it from a real person. The test involves a 'subject' placed in a room separate from the computer and person - so they can't see each other. The subject then communicates with the human and the computer via computer screens. If the subject cannot distinguish between computer or human responses - then the computer is deemed to have passed the test.
Alan M. Turing
The Turing Test - Doctor Who - was created in 2000.
Alan Turing is considered to be the father of computers because he invented the Turing machine. The Turing machine is thought to be the first model of a computer.
Imagine two people, intelligent person A and thick person B. Both are Turing testing a machine. Person B, being thick, cannot tell that it is a machine. The Turing Test says that the machine is still thinking. Person A can see through it and can tell the difference between its responses and those of someone who is actually thinking. So the Turing Test says the machine is not thinking. So it is and it isn't thinking, a clear contradiction and thus the Turing Test cannot be correct.
Alan Turing did not invent the computer. He worked during WW2 at breaking military codes. He also considered the concept, called a "Turing machine", which was a machine that could make itself. In his example, this was a tape machine (punched paper tape in those days) which could make itself. Most importantly, he posed the Turing Test, which was a test to decide whether a machine could develop intelligence. This test has so far resisted a 'yes' answer, but the performance of applicants continues to get better. There is a good reference to him in wikipedia.org.
