 +===== Danish (da) =====
 +
 +[[http://www.buch-kromann.dk/matthias/treebank/|Danish Dependency Treebank]] (DDT)
 +
 +==== Versions ====
 +
 +  * Original DDT 1.0 in the [[http://www.tei-c.org/index.xml|TEI-based]] [[http://www.buch-kromann.dk/matthias/dtag/|DTAG]] or [[http://www.ims.uni-stuttgart.de/projekte/TIGER/TIGERSearch/doc/html/TigerXML.html|Tiger-XML]] format
 +  * CoNLL 2006
 +
 +The original DDT is based on [[http://www.buch-kromann.dk/matthias/files/diss-Dec05.pdf|Discontinuous Grammar]]. It natively encodes dependencies and other relations such as anaphora. The CoNLL version contains only the dependency relations.
 +
 +==== Obtaining and License ====
 +
 +DDT is available under the [[http://www.gnu.org/licenses/gpl-2.0.html|GNU General Public License version 2]]. Download the original distribution (DTAG + TIGER-XML formats) from http://www.buch-kromann.dk/matthias/treebank/. Download the CoNLL 2006 conversion from http://ilk.uvt.nl/conll/free_data.html. The license in short:
 +
 +  * any usage, commercial or not
 +  * modification and redistribution under same license permitted
 +  * citation in publications not required (but it is common decency)
 +
 +DDT was created by members of the [[http://www.cbs.dk/en/Research/Departments-Centres/Institutter/ISV|Department of International Language Studies and Computational Linguistics]], Copenhagen Business School (Handelshøjskolen i København), Dalgas Have 15, DK-2000 Frederiksberg, Denmark. The underlying [[http://korpus.dsl.dk/e-resurser/vilkaar.php?lang=|PAROLE]] corpus (morphologically annotated) was created by the [[http://www.dsl.dk/|Society for Danish Language and Literature]] (Det Danske Sprog- og Litteraturselskab), Christians Brygge 1, DK-1219 København K, Denmark.

 +
 +==== Domain ====
 +
 +Unknown (the underlying PAROLE corpus “consists of quotations of 150-250 words from a wide range of randomly selected linguistically representative Danish texts from 1983-1992.”)
 +
 +==== Size ====
 +
 +The CoNLL 2006 version contains 100,238 tokens in 5512 sentences, yielding 18.19 tokens per sentence on average (CoNLL 2006 data split: 94386 tokens / 5190 sentences training, 5852 tokens / 322 sentences test).
 +
 +==== Inside ====
 +
 +The original morphosyntactic tags have been converted to fit into the three columns (CPOS, POS and FEAT) of the CoNLL format. There //should// be a 1-1 mapping between the [[http://www.buch-kromann.dk/matthias/treebank/PAROLE-manual.pdf|DDT positional tags]] and the CoNLL 2006 annotation. Use [[http://quest.ms.mff.cuni.cz/cgi-bin/interset/index.pl?tagset=da::conll|DZ Interset]] to inspect the CoNLL tagset.
 +
 +The morphological analysis in the CoNLL 2006 version does not include lemmas (the original DTAG version does contain them). The morphosyntactic tags have been assigned (probably) manually.
 +
 +Some multi-word expressions have been collapsed into one token, using underscore as the joining character. This includes adverbially used prepositional phrases (e.g. i_lørdags = on Saturdays) but not named entities.

 +==== Parsing ====
 +
 +Nonprojectivities in DDT are not frequent. Only 988 of the 100,238 tokens in the CoNLL 2006 version are attached nonprojectively (0.99%).
 +
 +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 Danish:
 +
 +^ Parser (Authors) ^ LAS ^ UAS ^

 +| Malt (Nivre et al.) | 84.77 | 89.80 |
