Download ppt - RECAPTCHA for translations

reCAPTCHA for translation

First look up Google

for “reCAPTCHA”


RECAPTCHA uses

a special CAPTCHA:

always two words


One word is a commonly known word

twisted and obfuscated deliberately,

to make it a useful CAPTCHA


The other is

a random, unscannable word

from the image

of a famous printed text


Hence the first word acts

like a primary check

on your being a human


And the second word

uses your human intelligence

by asking you to identify

what their OCR could not recognize.


They scan famous, public works.

The result is a free book for everyone,

made complete by identifying

one difficult word at a time!


They give you value (security)

They take from you value (identify un-OCRed word)

And then give back more(the book)

While being unobtrusive!


Translation needs public participation

Translation needs people's thought

Google is a good boy

They request your improvement.


But what if you're a bad boy?

Facebook, Microsoft, Tech News portal?

What if your user depends on you?

Can you force him to help?


Can you say:

Hi there!We'll show you the full page,

if you help us translate,just this one sentence,

into your native language?After all,

you're helping your own people!


Can you throw people a challenge?

Can you convince them to take it?

Can you give them points or money?

Can you coax them into action?


Can you ask them to ...

answer a translation CAPTCHA ?

Can this trick work?If you adapt it a bit?

If you add value?

Bittorrent? Pirate Bay? Wikipedia?


Help your own people!

Translate the stuff that the big guys cannot.(Google, BabelFish, etc)


Let's make the world better

for our less fortunate brethren,

One sentence at a time.

THANKS!!
