Ontologies for the Web's ??

Ontologies today lack of the flexibility needed for the Web. As a matter of fact, ontologies have been conceived for little communities of experts that try to agree on an "objective" model of a given domain of knowledge. To reach to an agreement about a model is often difficult, even in these little communities of experts. In large Web communities, don't even think about it...



So, should we renounce to ontologies as the foundation bricks of the Semantic Web vision?

I really don't know, but I'm trying to hint a possible solution of this problem.



Ontologies, as we intend them today, are based on Description Logics (DL). A Description Logic is based on an objective interpretation of the reality, not a subjective one. Nonetheless, there exist logics that model subjective interpretations (Epistemic Logic) and even subjective beliefs (Doxastic Logic). Is it possible that an ontology language based on the epistemic/doxastic logic would better fit the reality of the Web? Would reasoning be possible on models built with such a language?



Is there someone out there that can give me an answer?
