ENGLISH/ARABIC TREEBANK 1.0

This release of the English/Arabic TreeBank consists of 52,238 words in 224
files of individual Agence France Presse (AFP) news stories (corresponding
to approximately the first 50K words of the Arabic Treebank: Part 1 v 3.0
-- LDC Catalog No.: LDC2005T02, ISBN: 1-58563-330-5).  The English
translation was provided by LDC, and was part-of-speech tagged and
treebanked for this project.  The data can be found in the following
directories:

  Penn Treebank-style files (converted from WordFreak annotation files)
  /data/pennTB-style-trees/

  WordFreak annotated files
  /data/annotated-files/

  Source text files
  /data/rawtext-files/

The guidelines followed for both part-of-speech and treebank annotation 
are essentially Penn Treebank II style, with two notable differences:

1. POS: tokenization of hyphenated items ("New York-based" has been
   replaced by "New York - based" for example), and the addition of HYPH
   and AFX tags necessitated by this change in tokenization

2. TreeBank: the addition of the node label NML for sub-NP nominal
   constituents (replacing NX and most NP-internal NAC)

More detailed addenda to the Penn Treebank II guidelines can be found in
/docs/pos-guidelines-addenda.txt and
/docs/treebank-guidelines-addenda.txt

A mapping from the original Arabic Treebank filenames to the current
filenames used in this release can be found in
