The Arabic-PADT UD treebank is based on the Prague Arabic Dependency Treebank (PADT), created at the Charles University in Prague.


The treebank consists of 7,664 sentences (282,384 tokens) and its domain is mainly newswire. The annotation is licensed under the terms of CC BY-NC-SA 3.0 and its original (non-UD) version can be downloaded from http://hdl.handle.net/11858/00-097C-0000-0001-4872-3.

The morphological and syntactic annotation of the Arabic UD treebank is created through conversion of PADT data. The conversion procedure has been designed by Dan Zeman. The main coordinator of the original PADT project was Otakar Smrž.


We wish to thank all of the contributors to the original PADT annotation effort, including Otakar Smrž, Jan Hajič, Petr Zemánek, Petr Pajas, Jan Šnaidauf, Emanuel Beška, Jakub Kráčmar, and Kamila Hassanová.

Further corrections of additional data (not part of PADT release 1.0) were done by Shadi Saleh and Zdeněk Žabokrtský.
