In fact this goes exactly in the direction of the TF

Some papers on the TF page address these issues. 
Consider that both in OWN, and in other work, 
including the OWL version realized by Georgi Y. 
Dimitrov, the ambiguity of hypernymy has been

I'm collecting all them (I'll prepare an 
exhibition soon ;)). One task of the forthcoming 
note concerns the comparison of different 
proposals, ranging from the bare import of WN 
database into RDF, to complex reengineering like 
OWN (OntoWordNet)

OWN has been loaded into OilEd and Protege (SWOOP 
seems to fail), see related messages and 
description. Protege takes 8 minutes to load it 
on a Powerbook G4 1.5GHz.

I think option 2. is much better, and indeed is 
what I'm envisaging with the open-source 
collaboration project I would like to propose: 
any interested party could checkout a small 
module of WN, improve it, and check it in back to 
a collaborative platform

You're a perfect testimonial. Though I'd rather 
avoid thinking of such a project in commercial 
terms :)

Looking forward to hear you at Wednesday's telecon.
