Linguistic Data Consortium, Philadelphia


Arabic Treebank: Part 2 v 2.0 was produced by Linguistic Data Consortium (LDC) catalog number LDC2004T02 and ISBN 1-58563-282-1.

This publication is the second part of a corpus of 1,000,000 words of Arabic Treebank, designed to support language research and development of language technology for Modern Standard Arabic. Part one was released in 2003 as Arabic Treebank: Part 1 v 2.0, having the source data extracted from Agence France Press stories. The current Arabic Treebank: Part 2 v 2.0 corpus consists of stories from Al-Hayat distributed by Ummah.


This corpus includes 501 stories from the Ummah Arabic News Text. There are a total of 144,199 words (counting non-Arabic tokens such as numbers and punctuation) in the 501 files - one story per file. New features of annotation include complete vocalization (including case endings), lemma IDs, and more specific POS tags for verbs and particles.

The corpus contains 125,698 Arabic-only word tokens (prior to the separation of clitics), of which 124,740 (99.24%) were provided with an acceptable morphological analysis and POS tag by the morphological parser, and 958 (0.76%) were items that the morphological parser failed to analyze correctly.


There are no updates available at this time.
