Re: [semanticweb] how to explain to humans the term ontology

Pierre,
No need the same errors and confusions to repeat four times (this is how 
many times the public got your  emails).

Let me repeat just one time again.
There is [one General Ontology dealing with the world, its things, beings, 
and relationships], and many [domain ontologies dealing with the specific 
regions, parts, domains, or realms of reality.]
[Computing ontology is all about the representation of the world, its entity 
states, changes, and relationships, in machine-processible forms].

Always stick to reality and do the reality check in your thinking and 
research. Otherwise you will find youself completely lost in a cacophony of 
'definitions', like below:
'an explicit specification of conceptualization', 'a theory of content', 'a 
theory (a system) of concepts/vocabulary used as building blocks of 
information processing systems', 'a set of agreements about a set of 
concepts', or 'the representation of the semantics of terms and their 
relationships'. Alternatively, it is interpreted as 'the class hierarchy in 
object-oriented paradigm', 'a complete schema of the domain concepts', 'an 
entity-relationship schema with subsumption relations between concepts', 
'conceptual patterns', 'concept heterarchies or hierarchies', 'a body of 
conceptualizations', 'schemata', or 'metadata scheme', 'a common set of 
terms', 'a controlled vocabulary of terms', 'a representation vocabulary', 
or 'a body of knowledge', etc.

If real ontology confuses you, read carefully good papers, as i mentioned,' 
The Semantic Web', T. Berners-Lee et. al., if we are on this forum. Here is 
its gist: ''The challenge of the Semantic Web is to provide a language that 
expresses both data and rules for reasoning about the data...''.

Translate, [the semantic web is aimed to provide one ontological language 
that expresses the information (data) about the world and inference rules 
(mechanisms) about the data].

Very easy, if you have some insight into the matter.

I wonder for my part how you can be offended by such a general
statement. The challenge was to give a 'layman' account of ontology.
Compare with a definition of mathematics as a scientific discipline
occupied with tools and methods for dealing with numbers.

Last I heard of, it was common place in this field that ontology is
about 'specification of conceptualizations'. You must be referring to
philosophical ontology.

I was referring to ontology as a field in computer science. As such
ontology is a field of computer science and not of philosophy which is
what I think you have in mind here.

Now, there is what ontology is in computer science and how it should
be done. I stick with the view that CS ontology is about alleged facts
such as reported in databases. Nevertheless, I agree, if that is your
point, that this should be done in the way that ontology is done in
philosophy and with the same horizon, namely reality. But that debate
is not relevant here.

That's not ontology, that might be epistemology and taken literally
that's merely psychology. Such talk of concepts and mind is garbage
for the purpose of ontology, in fact both philosophical and computer
science ontology.

I'm saying CS ontology is what supports making these, but I'm not
convinced it's studying them.

Natural language semantics is garbage too (for the purpose of
ontology, I'm not saying it's pure garbage).

What does regionality has to do with this?

Maybe 'tools' isn't a general enough term for your liking then. Or
maybe I don't I understand what you mean by mechanisms for reasoning
over data.

Telling somebody what ontology is does not necessarily require that we
aknowledge all subtleties, methodologies, techniques, paradigms or
applications; giving a rough idea should suffice. You don't think that
what's so peculiar about computer science ontology is that it deals
with the structuration of data?

Cheers,
Pierre
