Recaptcha

Captcha ile ilk kez çeşitli sitelerin üyelik formları doldururken tanışmışızdır hepimiz. Bilgisayar tarafından geçerli işlemin insan tarafından yapıldığı, otomatikleştirilmediğini garanti eden captcha’ya dair ilginç bir istatistiki veri var:

About 60 million CAPTCHAs are solved by humans around the world every day. In each case, roughly ten seconds of human time are being spent. Individually, that’s not a lot of time, but in aggregate these little puzzles consume more than 150,000 hours of work each day.

İşte bu potansiyeli iş gücüne çevirmeyi düşünen Recaptcha grubu şöyle bir önerme getiriyor:

What if we could make positive use of this human effort? reCAPTCHA does exactly that by channeling the effort spent solving CAPTCHAs online into “reading” books.

reCAPTCHA improves the process of digitizing books by sending words that cannot be read by computers to the Web in the form of CAPTCHAs for humans to decipher. More specifically, each word that cannot be read correctly by OCR is placed on an image and used as a CAPTCHA. This is possible because most OCR programs alert you when a word cannot be read correctly.
