If this is desirable to promote is another point. (You also have more "useless" triples than when we'd make an additional conversion that converts it directly into a subclass hierarchy.) > > many hypernymOf relations refer to instanceOf (rd:type), and there are > > other problems.

BTW the new WN 2.1 version has a new "instance" relation; Paris is an instance of the synset "national capital" [1]. Time permitting this information could be incorporated. But still it would need data reengineering to turn it into a "clean" ontology. Cheers, Mark. [1]http://wordnet.princeton.edu/perl/webwn?o2=&o0=1&o6=&o1=1&o5=&o4=&o3=&s=Paris&i=4&h=100000000#c
