Comments on: doing my part http://kynthiabru.net/blog/archives/413 Thu, 11 Mar 2010 00:50:48 +0000 http://wordpress.org/?v=2.3 By: BlogSchmog | Blog Archive » reCAPTCHA = altruism http://kynthiabru.net/blog/archives/413#comment-30492 BlogSchmog | Blog Archive » reCAPTCHA = altruism Sun, 03 Jun 2007 05:57:59 +0000 http://kynthiabru.net/blog/archives/413#comment-30492 [...] I heard about reCAPTCHA not long before Kynthia tried it out. Leveraging 150,000 hours of collective typing work each day for some other noble purpose—such as helping digitize books from the Internet Archive—is a great idea … provided the existing action is necessary in the first place. According to the reCAPTCHA application site, human wisdom is mined this way: Each new word that cannot be read correctly by OCR is given to a user in conjunction with another word for which the answer is already known. The user is then asked to read both words. If they solve the one for which the answer is known, the system assumes their answer is correct for the new one. The system then gives the new image to a number of other people to determine, with higher confidence, whether the original answer was correct.

As I started typing, though, I thought of a question about it. It was <a href="http://davidernst.net/blog/wp-content/uploads/2007/05/broken-turntable.thumbnail.jpg" rel="nofollow">asked and answered on their website</a>: "But if a computer can't read such a CAPTCHA, how does the system know the correct answer to the puzzle?" Also very clever: it's always two words, and if you can do one, they let you in, and figure you probably did the other one correctly too. Then it gives the same image to a few people and if they all give the same answers, they assume it's correct. Kudos, recaptcha folks!

I haven't figured out what it is about! Well, this is a recaptcha experiment. I haven’t figured out what it is about!
