Digitizing books: one word at a time
25·May·07
A fantastic concept: kill 2 birds with 1 stone by having web users help to digitize old texts whilst they decipher online CAPTCHAs.
"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. 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."
