ReCaptcha - digitizing the world's knowledge one word at a time
I’ll say it - ReCaptcha is the most annoying thing on the internet.
But did you know you were helping to digitize all of human knowledge every time you logged into a site?
Here’s what you dint know. 👇
Every time you use ReCaptcha, there are 2 images placed before you wit warped text right?
These are actual images of a book scanned where OCR could not recognize the text.
One of the images is untranslated & while the other is already translated.
You enter the 2 words.
Your answers are compared with 10 other users for the unsolved image.
The common answer goes in to digitize the text.
Wait till you hear its impact.
Over a billion people have contributed to digitize texts using reCaptcha.
It contributes over 116,000 man-days each day - for free - to the cause.
ReCaptcha, in its hey-day, digitized over 2.5 million books a year.
The next time you solve one, remember, you are just doing your part as a human to make knowledge available to the digital world.
Are there any other such ingenious innovations you have come across?
Would love to learn of them.
