Great input, Evan. Thank you. (01)
Since slide#6 is authored by Leo, I'll defer it him (and hope that you
and he can talk it over in our upcoming call in person, or later.) (02)
On a separate note ... while the Semantic Web is one of the key areas
where ontologies are used, it is by far *not* the only place where KR,
computational linguistics, NLP, ... and all technologies relating to
ontologies and ontological engineering, or the need for semantic
interoperability begins and ends. We might need to take that into
account too. (03)
Thanks & regards. =ppy
