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. cheers, Dan
