Subject:   Request for Ontology Examples

Hello Rod,

[Responding to your letter on June 2, 2000 requesting examples applying the methods described on the Ontologos web site...]

Yes, I had been in some brief email discussions with Jack Park and Leo Obrst earlier this spring.

I am afraid my web site www.ontologos.org is a bit of a mess right now, since this year I am heavily involved in the theoretical development of what I call "onto logic".

If your title "Dynamic Knowledge Repository" is accurate as far as your intentions, then in my opinion, you have come to the right place. My intentions all along have been to subvert the usual opinion that classification involves a static notion that is not conducive to change "on the fly". That was part of the essence of the WAVE project that I directed at Washington State, where we had developed a "conceptual browser" over various domain contents. In that project we developed several metadata and ontologic frameworks, ending up at two markup languages OML/CKML. We partially developed ontologies in several domains (higher education, commerce & industry, movies & TV, etc) in order to challenge the design development of the markup languages and the knowledge management framework.

As I mentioned above, currently I am developing a logical theory for the ontologies (as discussed on the ontologies standards lists, for example), and terminologies (as expressed in description logic formalisms). I will present a paper at the 6th ISKO Conference on ontology sharing entitled...

The Information Flow Foundation for Conceptual Knowledge Organization


I have submitted another (rather theoretical) paper entitled...

Distributed Conceptual Structures

...that attempts to integrate Jon Barwise's theory of Information Flow with Rudolf Wille's Formal Concept Analysis. I am currently working on a paper that gives a fresh approach and rigorous model theory to the logic of ontological thinking entitled...

The Model Theory of Onto Logic

I do not know if any of this is of interest to you, but if you have any questions, please let me know. As soon as I finish the last paper (it is taking some time) I would like to get involved with some standards work (perhaps with the OIL group, perhaps with your group).

All the best,



Robert E. Kent
