On Thursday 29-March-2007, Dr. Steven Ray (NIST) presented the
5th Event in the Joint NIST-Ontolog-NCOR "Ontology Evaluation &
Measurement" Mini-Series. It was a panel discussion on the topic:
"Probabilistic Reasoning and Ontology Evaluation." On the expert
panel were Professor Kenneth Baclawski (Northeastern University),
Professor Kathryn Blackmond Laskey & Dr. Paulo Costa (both from
George Mason University), and Dr. Terry Janssen (Lockheed
Martin). Professor Baclawski, Professor Laskey and Dr. Costa
alternated between there opening briefings and explored with us
the landscape in ontological engineering efforts related to
uncertainty reasoning and enumerated the goals of those work,
with which we could use as criteria and dimensions for evaluating
the approaches and ontologies. And, as Dr. Janssen pointed out,
this is a very important area that should be given the attention
its due. The consensus is that we should follow-up and create
more opportunities for exchange and collaboration like this for
the community in the not-too-distant future. (01)
Our appreciations go out to Professor Baclawski, Professor
Laskey, Dr. Costa and Dr. Janssen for sharing their work and
insight with us. Thanks to Dr. Ray for championing this
mini-series; and, as always, to all the participants for joining
us and for contributing to the discussion we had during the session. (02)
Proceedings of the session are captured on our wiki page, at:

In particular, full audio recording of the session is now
available - see:

... we are glad we have captured this session into our archives
and have it preserved for posterity. This presentation and the
ensuing discussion contribute to yet another significant item in
the body of knowledge on ontology and ontological engineering
that our community is building together. Thanks again! (05)
Best regards. =ppy (06)

the 6th Event in the "Database And Ontology" Mini-Series - Mr.
Edward Barkmeyer from NIST will be our invited speaker and will
be giving a talk on "Ontologies as the Next Generation
Information Models." (08)
* Monday & Tuesday, 23 & 24-April-2007 - the "Ontology Summit
2007" face-to-face workshops and symposium will be held at NIST
