| http://www.w3.org/ns/prov#value | - CAPTCHA: CAPTCHA stands for Completely Automated Public Turing tests to tell Computers and Humans Apart. (That probably isn???t much help, but you???ll be a hit at parties.) In more practical terms, a CAPTCHA is a device used to detect if a human is completing an online form???like when you have to type a few bits of text from a scrambled image before you can submit a form.
