Subject: New LDC Arabic treebank offering

(1) Arabic Treebank: Part 1 v 4.1 was developed at LDC. It consists of 734 newswire  stories from Agence France Presse with part-of-speech , morphology, gloss and syntactic treebank annotation in accordance with the Penn Arabic Treebank (PATB) Guidelines developed in 2008 and 2009. This release represents a significant revision of LDC's previous ATB1 publications: Arabic Treebank: Part 1 v 2.0 (LDC2003T06) and Arabic Treebank: Part 1 v 3.0 (POS with full vocalization + syntactic analysis) (LDC2005T02). 

The ongoing PATB project supports research in Arabic-language natural language processing and human language technology development. The methodology and work leading to the release of this publication are described in detail in the documentation accompanying this corpus and in two research papers: Enhancing the Arabic Treebank: A Collaborative Effort toward New Annotation Guidelines and Consistent and Flexible Integration of Morphological Annotation in the Arabic Treebank. 

ATB1 v 4.1 contains a total of 145,386 tokens before clitics are split, and 167,280 tokens after clitics are separated for the treebank annotation.  Arabic Treebank: Part 1 v 4.1 is distributed on one DVD-ROM.

2010 Subscription Members will automatically receive two copies of this corpus.  2010 Standard Members may request a copy as part of their 16 free membership corpora. Non-members may license this data for US$4500.
