The Dutch WordNet
The Dutch WordNet is developed in the EuroWordNet project and improved in the Cornetto project. It is licensed by the Nederlandse Taalunie as part of the Cornetto database.
The Cornetto database is freely available for research. For commercial usage a fee needs to be paid to the Nederlandse TaalUnie. The license can be obtained from the TST-Centrale: http://www2.let.vu.nl/oz/cltl/cornetto/license.html. After obtaining a license for the Cornetto database, the Wordnet-LMF version can be obtained by contacting Piek Vossen ( firstname.lastname@example.org).
