Online Gaming Helps Index Finnish National Archive
Digitalkoot provides a platform where participants can play Mole Hunt and Mole Bridge: in both games players offer solutions to words which the computer can't recognise. It's all part of a larger effort index the National Libraries archive of newspapers.
Human based computation is an example of human-computer symbiosis, the best example being ReCAPTCHA: the human detecting security test that keeps out unwanted bot programs but also helps further text recognition of digitised texts.
A similar effort is underway in Finland, which makes use of video game dynamics, harking back to edutainment classics like The Typing Of The Dead. Digitalkoot is a collaborative endeavour between the National Library of Finland and Microtask, specialists in distributed workforces.
