Optical Character Recognition
OCR is the ability to scan a document (or grab a PDF file) and run an OCR program on it and it will generate, based on optical recognition and approximation, an editable text file. For an idea about OCR see http://www.students.cs.uu.nl/people/mjkammer/Work/intro_2_OCR.html
Current Status of Open Source Arabic OCR software
Actually (2007-08-27) The principal GPL OCR active utilities (OCRAD, GOCR, OCRE) doesn't support arabic printed text recognition. ClaraOCR project seems to be inactive, but its documentation promises to work well with any horitzontal-writing language.
Siragi-OCR
SIRAGI is an open source software designed to help blind and partially sighted people working with their computer. Visually impaired people can use this program to "listen" the content of their screen under windows or Linux/KDE. The main advantage of using SIRAGI is the support of arabic language for braille language and for speech synthesis in arabic.
As a part of This, Siragi's developer started devoloping a FOSS OCR that should support Arabic.
