Re: owl:sameAs links from OpenCyc to WordNet

David,

Sorry for missing this one earlier.  Yes indeed, OpenCyc's use of 
owl:sameAs caused me problems [1].

Your proposed solution of openCyc:synsetDenotes is interesting.  If your 
goal is coreference, I would invite you to make use oguid:identical [2]. 
  Hundreds of questionable (in terms of coreference) links from OpenCyc 
to WordNet and DBPedia have been addressed in the OpenGUID database [3]. 
  The data is in the public domain.

with questionable links removed)
