Re: your thought-provoking observation of the lack of published ontologies.
I agree wholeheartedly with the other circulated comments that that's where
the `meat' really is, and that it's a sorely neglected area.
But let me add a (maybe unjustified) concern: What I wouldn't like to
now see is a lot of isa-hierarchies published, with little or no information
in the general/top-level concepts. The whole notion of sharable KBs is based
on the idea of reusable, composable components of knowledge. So what I'd like
from an ontology paper is a library of components (eg. top-level frames,
general CGs), and a method for composing them to build the specific
representation I want (eg. multiple inheritance, maximal join). It's the
component library, not a specific representation built from it, which is what
is of interest, and is likely to have the long shelf-life.
For example, your ontology may model a room as a container but I want to
model it as a point location (or person as a thing/process, carpet as
in/partof the room etc.). This ontological distinction isn't really
important (it's a task-dependent question), and shouldn't distract the
debate -- what is important is that I have the components available in
the first place (ie. a representation of what it *means* to be a "container"
or a "point location") to be able to build either of these models as needed.
