Kalema: Digitizing Arabic Content For Accessibility Purposes Using Crowdsourcing

In this paper, we present "Kalema", a system for digitizing Arabic scanned documents for the visually impaired such that it can be converted to audio format or Braille. This is done through a GWAP which offers a simple, challenging game that helps attract many volunteers for this cause. We show how such a tedious task can be achieved accurately and easily through the use of crowdsourcing.
