The Danish Dependency Treebank v. 1.0 by Matthias Buch-Kromann (mbk.isv@cbs.dk) http://www.cbs.dk/staff/mbk Center for Research in Translation and Translation Technologies Department of International Language Studies and Computational Linguistics Copenhagen Business School revised April 2, 2004 revised April 16, 2010 1. Who owns the copyright to the Danish Dependency Treebank? The Danish Dependency Treebank is copyrighted material. * (c) 2002-2004 by Matthias Buch-Kromann and the Department of Computational Linguistics at the Copenhagen Business School, who own the copyright to all dependency annotations in the Danish Dependency Treebank. * (c) 1998 by the Society for Danish Language and Literature (http://www.dsl.dk), who own the copyright to the underlying PAROLE corpus and the "msd" and "lemma" annotations. The dependency annotations in the Danish Dependency Treebank were carried out in 2002-2003 by Matthias Buch-Kromann with the assistance of Stine Kern Lynge and Line Hove Mikkelsen. The PAROLE corpus was collected by Ole Norling-Christensen and the Society for Danish Language and Literature, and consists of quotations of 150-250 words from a wide range of randomly selected linguistically representative Danish texts from 1983-1992. The copyright to these quotations belongs to the authors of the original texts, and their inclusion in the PAROLE corpus is licensed by §22 in the Danish law on Copyright (lovbekendtgørelse nr. 618 af 27. juni 2001) which states that it is permitted to quote from copyrighted works according to a "fair use" principle. The source of each quotation is listed in the DTAG encoded treebank files (for technical reasons, meta information cannot be encoded in the corresponding TIGER-XML encoded treebank files). 2.

It is not as powerful as DTAG, but some users may find it more user-friendly and easy to install. 6.
