Version 0.1 contains 9581 tokens in 600 sentences, yielding 15.97 tokens per sentence on average. We defined the following data split: 7592 tokens / 480 sentences training, 1989 tokens / 120 sentences test.

Tamil script has been romanized (the romanization is case-sensitive).

The treebank is distributed in three formats: TMT (TectoMT XML), CoNLL and TnT-tagger style (only POS-tagged layer).

Morphological annotation is manual and it includes lemmas, parts of speech and morphosyntactic features. Syntactic annotation follows the style of the Prague Dependency Treebank.

Nonprojectivities in PADT are rare. Only 431 of the 116,793 tokens in the CoNLL 2007 version are attached nonprojectively (0.37%).

The results of the CoNLL 2006 shared task are available online. They have been published in (Buchholz and Marsi, 2006). The evaluation procedure was non-standard because it excluded punctuation tokens. These are the best results for Arabic:

Parser (Authors)	LAS	UAS
MST (McDonald et al.)	66.91	79.34
Basis (O'Neil)	66.71	78.54
Malt (Nivre et al.)	66.71	77.52
Edinburgh (Riedel et al.)	66.65	78.62

The results of the CoNLL 2007 shared task are available online. They have been published in (Nivre et al., 2007). The evaluation procedure was changed to include punctuation tokens. These are the best results for Arabic:

Parser (Authors)	LAS	UAS
Malt (Nilsson et al.)	76.52	85.81
Nakagawa	75.08	86.09
Malt (Hall et al.)	74.75	84.21
Sagae	74.71	84.04
Chen	74.65	83.49
Titov et al.	74.12	83.18

The two Malt parser results of 2007 (single malt and blended) are described in (Hall et al., 2007) and the details about the parser configuration are described here.
