Re: summary of state-of-play

Guido, all,

  in his 1994 AAAI Paper 
(http://www.mit.bme.hu/system/files/oktatas/targyak/7412/Formalizing_Ontological_Commitments.pdf) 
Guarino talks about " an ontological commitment for L" where L is a 
logical language. For me, it thus seems natural to see the ontological 
commitment as a "property" of language L. Under this view, it is the 
vocabulary that is in the domain of the commitsTo property and the 
"conceptual relation" is in the range.

But of course this is quite arbitrary. We need to define it properly I 
agree.

See below...

Yes

No, it means that a particular lexical concept (e.g. a synset) subsumes 
or includes the particular sense of a word. If you have a better way of 
naming this, please say so! I feel we do not yet have the ideal name for 
it. For example, a synset (as a lexical concept) includes not really a 
word, but a sense of a word.

Yes, it is equivalent to sense o inverse-of-subsumes
