Summary
The Danish UD treebank is a conversion of the Danish Dependency Treebank.
Introduction
The Danish UD treebank has been converted from the Danish Dependency Treebank (Buch-Kromman,2003) into Universal Dependencies (UD). It consists of 5,512 sentences (100k words). The Danish source texts and the Danish part-of-speech tags were created by the PAROLE-DK project (Keson 1998) by the Danish Society for Language and Literature.
In the DDT formalism, determiners head nouns, and auxiliaries head verbs. In order to promote content words to heads, we have applied a cascade of graph transformations that make function words (determiners, auxiliaries, conjunctions, etc) leaves in the dependency tree, instead of intermediate elements between content heads.
The part-of-speech tags and labels from the original treebank have been partially converted using mappings, and partially using the new calculated tree structure as a reference to assign labels.
The Danish Dependency Treebank was released under the GNU GPL license, hence that license can be used for UD_Danish as well. However, since GPL is more suitable for programs than for data (see github.com/UniversalDependencies/docs/issues/296 for a discussion), we asked for and Matthias Buch-Kromann was kind enough to grant the permission to use the Creative Commons license as an alternative.
