We had a really wonderful kick-off session for the
"Ontology Measurement & Evaluation" mini-series yesterday. (01)
The session began with brief opening remarks by the co-organizers
Professor Barry Smith (NCOR), Mr. Peter Yim (Ontolog) and Dr.
Steven Ray (NIST), each explaining why this work is important
from the perspective of the organization they represent.
Following that, Dr. Ray (program lead) kicked-off the program by
providing an overview on the series of events to come. He
solicited further suggestion from the community for
speakers/panelists and topics of interest. Dr. Ray also suggested
the possibility of engaging the community into collaboratively
developing an open document of key aspects of "Ontology
Measurement & Evaluation." This could be in the form of an open
wiki article/handbook, which could also be considered a
deliverable of this series. (02)
He then introduced our keynote speaker Dr. Chris Welty from the
IBM Watson Research Center. Dr. Welty gave a lively talk on:
"Ontology Quality and the Semantic Web," providing some of the
key tenets of a high quality ontology, and debunking the myth
that good ontologies may not be necessary for the semantic web
(as some believes that the likes of "folksonomies" are good
enough.) An enthusiastic discussion followed. (03)
Our appreciations go out to Dr. Ray, Dr. Welty and all who
contributed to yesterday's session and to making this series
happen. And, as always, thanks to all participants who joined us.
Proceedings of the session are captured at our wiki page, at:
In particular, audio recording of the session (as well as the
podcast and telephone playback of it) is now available too - see:

P.S. On next Thursday, 26-October-2006, Dr. Pat Hayes from the
Florida Institute for Human & Machine Cognition ("IHMC") will be
our invited speaker. His presentation: "A logic for ontology
interoperation" will mainly be about "Common Logic (CL)" - a
system of logical notations and formalisms that can act as an
expressive foundation for ontology interchange. CL is currently
going through ISO approval to become "ISO Common Logic". This is
important, as far as this community and our domain is concerned.
RSVP now (to the sender offline) to register your attendance. ...
