Thanks Aldo.

My immediate need is to better understand the relationship between WN and OWL. The objectives for the TF are the exact things I want to know better.

Specifically, I want to use an OWL version of WN, and augment it with some domain-specific terms and make use of it for an internal project.

I know that there are plenty of shortcomings of WN when viewed as an ontology, (such as semantically dubious hypernymy relationships). Is there any advice one can give to diminish the impact of such shortcomings?

Is there more than one OWL version of WN? Are the differences important? Is there a 'best' one to download?

Has anyone tried to upload an OWL WN into Protégé, or any other OWL editor? Would it handle it? I'm going to try it out and see...

Is there any experience with people who wish to build a domain-specific extension to WN, say that would include lots of jargon common in any technical field. Various issues/options come to mind.
1. One might extend the OWL version of WN with the new concepts, and not have a separate ontology for the domain.
2. Build a separate OWL ontology, (a real ontology, with relations, constraints etc), and then extend WN semi-automatically by extracting the class hierarchy (and leaving the richer domain ontology intact, possibly for other purposes)

Such are my practical concerns and questions. Think of me as a [the first?] real customer for the products of this Task Force.

I still need to do more reading of the archives to get up to speed.
The best thing anyone could do for me right away, is give me a very small number of pointers of what to read first.

Thanks,
Mike

Hi Mike,

I don't know about Jeremy and Guus, but I have been unavailable for 
much time. I still plan to return on this, and have new links, like 
the ISLE model for lexical repositories (I had ported it to OWL), 
which I want to submit to the WN-TF as a starting point for a general 
treatment of lexica.

On the second TF activity (WordNet as an ontology), I also have an 
OWL ontology of WordNet noun synsets, aligned to DOLCE, for those 
interested. But I cannot actively work on these issues for at least 
two weeks. Contact me if you need some urgent material.

Cheers
Aldo
