How Plagiarism Software Found a New Shakespeare Play - Yahoo! News: "Vickers detected 200 strings of three or more words in Edward III that matched phrases in Shakespeare's other works. Usually, works by two different authors will only have about 20 matching strings. 'With this method we see the way authors use and reuse the same phrases and metaphors, like chunks of fabric in a weave,' says Vickers. 'If you have enough of them, you can identify one fabric as Scottish tweed and another as plain gray cloth.' (No insult intended to Kyd.)"
