We are always talking about MOAT here, with the same architectures, the 
same systems. Don't forget that MOAT is supported by a server side 
system that helps users to relate a tag to meaning(s). It is a 
semi-supervised system.

We are, in fact, talking about how to describe what Alex put in his 
system: what is the best way to describe the things he envisioned (the 
meanings, the tags, etc)

Depends on the system.

It is really about the semantic of the vocabulary: what is a meaning? 
How to relate a meaning? how to describe a meaning? etc.

Taxonomies, not ontologies (SKOS is a taxonomy that helps people 
describing taxonomies).

Excessive I am not sure; not the best thing to do: possibly. We are 
really discussing about pros and cons here.

Exactly the same way as the current MOAT.

Same as here. A dataset is used for this (currently DBPedia)

Yeah, it is as simple as the current MOAT.

Question: can a named entity mean something (so, being related as the 
essence of a meaning (like in MOAT)).

I have some doubts about that.

So, does it make sense to say: I have a tag "physics" that has a meaning 
that is represented by the URI of "Albert Einstein"? Does Albert really 
*mean* "physics"? I don't think so, but this could be possible with the 
current ontology.

This is what I am thinking about right now.


Take care,

Fred
