Summary
The NYUAD Arabic UD treebank is based on the Penn Arabic Treebank (PATB), parts 1, 2, and 3, through conversion to CATiB dependency trees.
Introduction
The treebank consists of 19,738 sentences (738889 tokens), and its domain is mainly newswire. The annotation is licensed under the terms of CC BY-SA 4.0, and the original PATB can be obtained from the LDC’s official website.
The morphological and syntactic annotation of the NYUAD Arabic UD treebank is created through automatic conversion of the PATB data.
