I have all the RDF/OWL files available for Wordnet here : http://www.w3.org/2006/03/wn/wn20/
I want to import them to the a new graphical database.
Thanks in advance,
There is a good paper (http://www.thinkmind.org/index.php?view=article&articleid=dbkda_2013_1_10_30004) describing a possible approach.
