I’m proud to announce the development of the Linguistic Analyzer (Almuhalil Alloghawy) tool, which is a free tool designed by a team from Al-Imam Muhammad bin Saud Islamic University that can be used for corpus analysis and comparison in terms of the several linguistic characteristics, such as frequency lists generation, concordances, collocation extraction, the difference between two words, and keyword identification.
You can download the tool from here.

Dear Maha,
it is great to read your blog posts, you have new software for Arabic corpus researchers! I have forwarded your blog post to Arabic researchers at Leeds, and world-wide. I hope you get users for your software.
Do you know Abdullah Alfaifi and Abdulrahman Alosaimy? I supervised their PhD projects at Leeds University, then they returned to Al-Imam U iversity in Riyadh, to be associate professors in computing. Are they in the same department as you?
Please keep in touch
regards
Eric
