Yes.  In general, however, we don't know what any of these relationships 
really is, because nearly none of them is formally defined in terms of 
any well-defined terms, and most of them are just links.  Even the ones 
that are in RDF are primarily written in terms that are effectively 
"primitive", being linked to HTML articles that describe them in detail, 
and discuss the vagaries in definition and interpretation instead of 
defining them.  What we are seeing is the Web version of a bunch of 
student papers referencing each other, and a few reliable major works 
that some of those papers are consistent with.  A lot of the links are 
blissfully ignorant of what Pat Hayes calls the 'Horatio Principle' -- 
the set of all X in my world and the set of all X in your world might be 
different enough to support different universal axioms.  Put another 
way, IF you had usable ontologies for all the stuff that is being linked 
together, the overall 'theory' would almost certainly be internally 
inconsistent.  So the question is whether this rapidly growing thing is 
creating knowledge or just further complicating the overflow of 
disorderly information.  The Linked Web is going to be rather like 
telephone systems of 1910 -- essentially chaotic until the perception 
of  the relationship between order and value overcomes the "first in 
your neighborhood" syndrome.    (02)

And a great many utterly uninformed and uninformative postings, to say 
nothing of baseless attacks and deliberate frauds.  The question is: 
what portion of that cacophony is signal?  And how would you know?    (04)

Oh, we have "critical mass", to be sure.  The problem is to harness it 
to provide controlled useful energy instead of Hiroshima (and to protect 
the results from the next data tsunami, or the next "revolution" in web 
technology).     (06)
