Certainly a useful concept to have name(s) for, ... but I think not 
quite what is needed to link these specific datasets. The W3C wordnet 
data is a collection of descriptions of linguistic concepts. The OpenCyc 
things they're linked to are not linguistic entities, but the real world 
things the words are associated with. So they're not near-identical 
similar objects, but things that are generally from disjoint classes. 
Paris the place, vs "Paris" the word (or the set of synonymous words 
_for_ Paris...). I think this is a distinction worth keeping reasonably 
explicit.
