= Man or machine: Turing test = By Daniel

The Turing test was introduced by Alan Turing in his 1950 paper "Computing Machinery and Intelligence". The Turing test experiment involves a human judge who asks questions to two contestants. One of which is a computer terminal and one which is a human being. Without knowing which is which. From the answers he/she receives they must try and guess which contesta nt is human **(** **The test does not check the ability to give the correct answer; it checks how closely the answer resembles typical human answers) **If the judge is unable to determine which is which, Turing suggested that the machine should be considered 'intelligent' In simple terms:

A machine could be considered intelligent if a machine could pass itself as human You can try the turing test on theses sites: http://www.cleverbot.com/ http://alice.pandorabots.com/

CAPTCHA

A more modern form of the Turing test is often seen on the web. **CAPTCHA** images are commonly used when posting comments on forums and when creating new user accounts online. CAPTCHA which stands for **Completely Automated Public Turing Test to tell to Computer and Humans Apart** are designed to prevent spam bots from posting adverts in comments or creating false accounts. CAPTCHA display deformed text which will hopefully be legible to a human being but not to the computer. If a computer (in this case an automated program) is able to read the text correctly, it has, in this case, made itself indistinguishable from a human and could be said to have passed the Turing test.
