Hi Dan,
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.
Sorry, I probably haven't been clear with my email (at least, Mike told me I was not ;))
I *was not suggesting* to use it, but probably more a subpropertyof seeAlso (even though, this is probably not the right one as a super property).
Why I did talk about umbel:isLike is to make people aware of its existence to try not over-using owl:sameAs where there is uncertainty in the linkage of instances of classes.
But I agree that this "umbel:isLike" property shouldn't be used in this case for the reason you described above.
And I do agree that these two instances belongs to disjoint classes (at least it was my interpretation of a wn:NounSynset and a opencyc:IndependantCountry).
Sorry for not having been clear in my first email. Thanks, Take care, Fred
