-The CoNLL 2006 and 2007 versions are obtainable upon request under similar license terms. Their publication in the LDC together with the other CoNLL treebanks is being prepared. +

-PADT was created by members of the [[http://ufal.mff.cuni.cz/|Institute of Formal and Applied Linguistics]] (Ústav formální a aplikované lingvistiky, ÚFAL), Faculty of Mathematics and Physics (Matematicko-fyzikální fakulta), Charles University in Prague (Univerzita Karlova v Praze), Malostranské náměstí 25, Praha, CZ-11800, Czechia. The CoNLL conversion of the treebank was prepared by Otakar Smrž, one of the key authors of the original PADT. +

- +
-According to their website, the original PADT 1.0 contains 113,500 tokens annotated analytically. The CoNLL 2006 version contains 59752 tokens in 1606 sentences, yielding 37.21 tokens per sentence on average (CoNLL 2006 data split: 54379 tokens / 1460 sentences training, 5373 tokens / 146 sentences test). The CoNLL 2007 version contains 116,793 tokens in 3043 sentences, yielding 38.38 tokens per sentence on average (CoNLL 2007 data split: 111,669 tokens / 2912 sentences training, 5124 tokens / 131 sentences test). +
- +
-As noted in (Nivre et al., 2007), “the parsing units in this treebank are in many cases larger than conventional sentences, which partly explains the high average number of tokens per sentence.” +

- +
-==== Inside ==== +
- +
-The original PADT 1.0 is distributed in the [[:format-fs|FS format]]. The CoNLL versions are distributed in the [[:format-conll|CoNLL-X format]]. The original PADT contains more information than the CoNLL version. There is morphological annotation (tags and lemmas) both manual and by a tagger (while only manual is in CoNLL data), glosses etc. However, the most important piece of information that got lost during the conversion to CoNLL is the FS attribute called ''parallel''. It distinguishes conjuncts from shared modifiers of coordination and thus the syntactic structure is incomplete without it. +
- +
-Word forms and lemmas are vocalized, i.e. they contain diacritics for short vowels as well as consonant gemination and a few other things. The CoNLL 2006 version includes [[http://www.qamus.org/transliteration.htm|Buckwalter transliteration]] of the Arabic script (in the same column as Arabic, attached to the Arabic form/lemma with an underscore character). +
- +
-Note that tokenization of Arabic typically includes splitting original words (inserting spaces between letters), not just separating punctuation from words. Example: وبالفالوجة = wabiālfālūjah = wa/CONJ + bi/PREP + AlfAlwjp/NOUN_PROP = and in al-Falujah. In PADT, conjunctions and prepositions are separate tokens and nodes. +
- +
-The original PADT 1.0 uses 10-character positional morphological tags whose documentation is hard to find. The CoNLL 2006 version converts the tags to the three CoNLL columns, CPOS, POS and FEAT, most of the information being encoded as pipe-separated attribute-value assignments in FEAT. There //should// be a 1-1 mapping between the PADT positional tags and the CoNLL 2006 annotation. The CoNLL 2007 version uses a tag conversion different from CoNLL 2006. Both CoNLL distributions contain a README file with a brief description of the parts of speech and features. Use [[http://quest.ms.mff.cuni.cz/cgi-bin/interset/index.pl?tagset=ar::conll|DZ Interset]] to inspect the two CoNLL tagsets. Also look at the [[http://quest.ms.mff.cuni.cz/cgi-bin/elixir/index.fcgi|Elixir FM online interface]] for a later development of the morphological analyzer created along with PADT. +
- +
-The guidelines for syntactic annotation are documented in the [[http://ufal.mff.cuni.cz/padt/PADT_1.0/docs/guides/PADT_Analytical.pdf|PADT annotation manual]] (only peculiarities of Arabic are documented, otherwise it is referenced to the annotation manual for the Czech treebank). The list and brief description of syntactic tags (dependency relation labels) can be found in [[http://ufal.mff.cuni.cz/padt/PADT_1.0/docs/papers/2002-flm-padt.pdf|(Smrž, Šnaidauf and Zemánek, 2002)]]. +

They have been published in [[http://aclweb.org/anthology-new/W/W06/W06-2920.pdf|(Buchholz and Marsi, 2006)]]. The evaluation procedure was non-standard because it excluded punctuation tokens.

-==== Parsing ==== +
- +
-Nonprojectivities in BTB are rare. Only 747 of the 196,151 tokens in the CoNLL 2006 version are attached nonprojectively (0.38%). +
- +
-The results of the CoNLL 2006 shared task are [[http://ilk.uvt.nl/conll/results.html|available online]]. They have been published in [[http://aclweb.org/anthology-new/W/W06/W06-2920.pdf|(Buchholz and Marsi, 2006)]]. The evaluation procedure was non-standard because it excluded punctuation tokens. These are the best results for Bulgarian: +

-Hyderabad Dependency Treebank (HyDT-Bangla) +
- +
-==== Versions ==== +
- +
-  * ICON 2009 +

- +
-There has been no official release of the treebank yet. There have been two as-is sample releases for the purposes of the NLP tools contests in parsing Indian languages, attached to the [[http://ltrc.iiit.ac.in/nlptools2009/|ICON 2009]] and [[http://ltrc.iiit.ac.in/nlptools2010/|2010]] conferences. +
- +
-==== Obtaining and License ==== +
- +
-There is no standard distribution channel for the treebank after the ICON 2010 evaluation period. Inquire at the LTRC (ltrc (at) iiit (dot) ac (dot) in) about the possibility of getting the data. The ICON 2010 license in short: +
- +
-  * non-commercial research usage +
-  * no redistribution +
- +
-HyDT-Bangla is being created by members of the [[http://ltrc.iiit.ac.in/|Language Technologies Research Centre]], International Institute of Information Technology, Gachibowli, Hyderabad, 500032, India. +
- +
-==== Domain ==== +
- +
-Unknown. +
- +
-==== Size ==== +
- +
-HyDT-Bangla shows dependencies between chunks, not words. The node/tree ratio is thus much lower than in other treebanks. The ICON 2010 / CoNLL version contains 7252 chunk nodes (not tokens – see below) in 1129 trees, yielding 6.42 chunks per sentence on average (ICON 2010 data split: 6440 chunks / 979 sentences training, 812 chunks / 150 sentences test). +
- +
-According to the data description file supplied with the data, there are 980 (training only?) sentences with 10305 words, which yields 10.52 words per sentence on average. +

-==== Inside ==== +
- +
-The text uses the [[http://ltrc.iiit.ac.in/nlptools2010/files/documents/map.pdf|WX encoding]] of Indian letters. If we know what the original script is (Bengali in this case) we can map the WX encoding to the original characters in UTF-8. WX uses English letters so if there was embedded English (or other string using Latin letters) it will probably get lost during the conversion. +
- +
-The CoNLL format contains only the chunk heads. The native SSF format shows the other words in the chunk, too, but it does not capture intra-chunk dependency relations. This is an example of a multi-word chunk: +
- +
-<code>3       ((      NP      <fs af='rumAla,n,,sg,,d,0,0' head="rumAla" drel=k2:VGF name=NP3> +
-3.1     ekatA   QC      <fs af='eka,num,,,,,,'> +
-3.2     ledisa  JJ      <fs af='ledisa,unk,,,,,,'> +
-3.3     rumAla  NN      <fs af='rumAla,n,,sg,,d,0,0' name="rumAla"> +
-        ))</code> +
- +
-In the CoNLL format, the CPOS column contains the [[http://ltrc.iiit.ac.in/nlptools2010/files/documents/Chunk-Tag-List.pdf|chunk label]] (e.g. ''NP'' = //noun phrase//) and the POS column contains the [[http://ltrc.iiit.ac.in/nlptools2010/files/documents/POS-Tag-List.pdf|part of speech]] of the chunk head. +
- +
-Occasionally there are ''NULL'' nodes that do not correspond to any surface chunk or token. They represent ellided participants. +
- +
-The [[http://ltrc.iiit.ac.in/nlptools2010/files/documents/dep-tagset.pdf|syntactic tags]] (dependency relation labels) are //karaka// relations, i.e. deep syntactic roles according to the Pāṇinian grammar. There are separate versions of the treebank with [[http://ltrc.iiit.ac.in/nlptools2010/files/documents/mapping_fine-to-coarse.pdf|fine-grained and coarse-grained]] syntactic tags. +
- +
-According to [[http://ltrc.iiit.ac.in/nlptools2010/files/documents/toolscontest10-workshoppaper-final.pdf|(Husain et al., 2010)]], in the ICON 2010 version, the chunk tags, POS tags and inter-chunk dependencies (topology + tags) were annotated manually. The rest (lemma, morphosyntactic features, headword of chunk) was marked automatically. +
