Dear Michael,

 

The second reference, which is a tad long, states, among other things:

 

Access is dependent on architecture. It is precisely by providing a space of names for access that Web architecture is useful. In order to be useful, access should be unambiguous. In contrast, reference to natural entities is inherently ambiguous. In this manner, reference on the Web is the same as reference off the Web. This is simply obvious. The Web is a transport mechanism for (what are in the REST sense) representations such as web pages. What a representation represents, and how the names in it refer, has nothing particularly to do with how the representations are transported. In the words of Korzybsky, “the map is not the territory” (1931). Web architecture does not determine what any names, including URIs, refer to. It only determines what they access.

 

I think that description succinctly captures the utopian vision of “meaning” that is so often misrepresented as in the SW descriptions.  URIs can only hold one file, and that file is, as he says, “inherently ambiguous” because the web is all about language, and language is inherently unambiguous. 

 

The SemWeb, much of the ontology work, and most of what passes for semantics technology, is actually Peirce’s “sign”, containing no meaning at all.  Meaning is in the mind of the interpreter who reads the material and assigns only her personal meaning.  There is no objective “meaning” by definition.  What you mean by a sign is very, very personal.

I never implied that the semantic web defines exact meaning. This

is impossible and not necessary. See:

I agree with John that 'the overwhelming number of OWL "ontologies" published

on the WWW just take the informal info from a terminology, put angle brackets

around it, and call it an ontology' but I do not agree with him that you do

not get extra value out of this. The extra value lies in introducing the

informal term into a formalism where the context of every term is clear which

is not true of natural languages where one word can have several completely

different meanings depending on context.

You can describe things in a manner that's human- and/or machine-comprehensible. Of course, you can't describe a 3rd parties mind (i.e., inner thoughts) with 100% accuracy.

The buzz-phrase "Semantic Web" is all about the use of hypermedia to enhance structured data representation (i.e., making it web-like) in a manner that also includes entity type, relationship, and relation semantics.
