Steve, First, we at VMASC (Dr. Andreas Tolk, Saikou Diallo and I) are currently exploring our options for participation in April. This sounds great. Second, your idea seems like a great position to start from, and we definitely want to contribute to the conversation. One of the things that our research has been trending towards is the idea of an upper ontology for a domain being captured in terms of "concepts" (for lack of a better term - there is some controversy here already), which are symbols representing the universal ideas that compose up the terms required for interoperability within that domain. If this is possible, then a central concept model can exist, with translations in and out of that central model for all of the semantic terms for systems that wish to interact - and by mapping their terms to those central concepts, they can then be re-oriented for consumption by any other system in the domain. This approach will no doubt produce gaps, which will then have to be accounted for. The approach is not perfect, and the theory behind it is still developing, but we have had some early successes at the term level. Our domain is the interoperability space existing between military simulations and military command and control systems.

OK, here's an idea to throw around:
The unique aspect of the Ontolog Forum is that, rather than just convening
conferences where people hear of others' work, the Forum actually establishes
positions. Last year, we produced the communique that represented the commitment
of the major upper ontology stakeholders to work together for a common good. So,
for this coming year, what might be a similar contribution - something that
could represent the combined voice of the community?
How about:
Semantic Mapping
or
How we must learn to love heterogeneity
Given that we will always be in a world where multiple ontologies coexist, what
choices do we have for mapping, or linking, concepts among these ontologies?
Must we be content with simply having humans assert semantic equivalence? If so,
what hope is there for automated integration? Is there potential in using
pattern-matching algorithms? Is is realistic to believe that reasoning systems
will be able to discover and/or prove semantic equivalence between concepts in
different ontologies?
What is the position of the Ontolog Forum?
I await reaction...

Peter,
This summarizes well our discussion. We invite you all to participate, and make
suggestions on the wiki on topics you'd like to see addressd this coming year at
the as yet unnamed forum/summit.
Thanks!
Leo

Subject: Planning another NIST-Ontolog joint event for April 2007
All,
For those of us who were at FOIS-2006 and attended the NCOR plenary meeting
there (evening of 09-Nov-2006), you might remember Steve Ray mentioning that
NIST will be hosting their "Interoperability Week" again in 2007, and it is
tentatively scheduled for the week of
23-April-2007 at Gaithersburg, Maryland, USA.
Following the success of the "Upper Ontology Summit"
that Ontolog and NIST co-organized for the same occasion earlier this year
(Interoperability Week - Mar. 2006) we are planning to put together another one
for April 2007.
Steve Ray, Leo Obrst and I had briefly discussed the matter (while we were all
at the FOIS conference) and decided that we will not be limiting ourselves to
just addressing upper ontology issues this time. We also agreed that we wanted
more than the 1.5~2.0 months worth of virtual discussion among the conveners,
prior to the face-to-face event, to allow us to gather more input from the
community and to better plan the program.
This is a call for suggestions and participation.
Similar to our last event (please refer to:
http://ontolog.cim3.net/cgi-bin/wiki.pl?UpperOntologySummit),
we would want to form a team of "conveners", comprising (besides the
organizers), key-participants and co-sponsors. If you are interested, please
drop us (Steve, Leo and I) a note off-line indicating your interest. We will
start a separate mailing-list shortly to engage this group to help put this
event together.
In particular, if you were one of the conveners of the
Mar.2006 UpperOntologySummit, we look forward to your continued participation.
Also, if your institution or company endorses the type of work we are doing,
please start trying to convince them to be our co-sponsor.
Anything else ... Steve? Leo?
We look forward to hear from as many of you as possible. RSVP now.
Thanks & regards. =ppy
