Well, probably not literally "fuzzy set logic", but
one might THINK of the PageRank as yielding a degree
of membership in the fuzzy set defined by the query.
I personally find this a very useful conceptual model
... not sure if it is a "conceptual graph."  I also,
FWIW,  think of SpamBayes as evaluating the "degree of
membership in the fuzzy set of 'spam'", for what it's 
worth.  I vaguely recall (from grad school in the
'70s) that Bayes Theorem is isomorphic to some fuzzy
set theorem (of Zadeh?) ...

That's a very interesting idea, IMHO.  I think of the
RDF/OWL semantics as being driven by classical set
theory / non-fuzzy logic, but maybe they can be
extended to handle fuzziness as neatly as has been
done with set theory and logic themselves.  

Anyway, I'm fascinated by these ideas Didier has been
throwing out, and I hope they go somewhere!
