Arabic Treebank: Part 1 v 2.0 was produced by Linguistic Data Consortium (LDC)
catalog number LDC2003T06 and ISBN 1-58563-261-9. This publication is part one of a
a corpus of one million words of Arabic Treebank, designed to support language research
and development of language technology for Modern Standard Arabic.
The Penn Arabic Treebank, which is part of the DARPA TIDES project, started
in the Fall of 2001 with the objective of performing human and computer annotations
of a large Arabic machine-readable text corpus (for project background please see
As in previous Penn Treebanks, two different kinds of information need to be
produced by two different (human and computer) processes. The Arabic
Treebank project consists therefore of two distinct phases:
- Part-of-Speech (POS) tagging - divides the text into lexical tokens,
and gives relevant information about each token such as lexical category,
inflectional features, and a gloss
- Arabic Treebanking (ArabicTB) - characterizes the constituent structures of word
sequences, provides categories for each non-terminal node, and identifies null elements,
co-reference, traces, etc.
Both tasks started in November 2001 with an
initial pilot consisting of 734 files representing roughly 166K words of
written Modern Standard Arabic newswire from the Agence France Presse corpus.
The target of this publication is to provide a description of a written Modern Standard
Arabic text corpus. The source data consists of Agence France Presse (AFP) newswire,
spanning from July through November of 2000.
This publication includes 734 stories representing 140,265 words (168,123 tokens after
clitic segmentation in the Treebank).
There are no updates available at this time.
