Hi Francois-Paul:

I'm a lurker on the skos list and a more regular participant on the 
ontolog forum where we discuss this issue quite regularly.

The short answer is yes, semiosis and pragmaticism. The RDF semantics 
document is clear that it provides only a mechanical representation of 
meaning, or truth mapping to the world called an interpretation. In 
order to establish the kind of meaning you're looking for, you need to 
extend the skos vocabulary to include both representation and 
interpretation. Here's a a pointer to the ongoing discussion ...

I think you'll enjoy following this thread. In support of what is 
referred to in the discussion as a relational theory of meaning, I make 
available under a creating commons "by license" an OWL ontology based on 
Charles Sander's Peirce's "On a New List of Categories" which is 
grounded in Peirce's early semiotics.

You can find that here ...

Swoop and Pellet are the reference implementation. One you load the 
ontology, turn on Pellet and you'll see the list classify as categories. 
Of course there's much work to do, but I am happy to share with the skos 
community.
