Subject:   Greetings again

My continued apologies for not keeping up the dialog with you. As you noted in your last phone mail to me, it's pretty crazy around here.

Anyway, I'm still strongly interested in keeping up with the disparate activities of the collective out there, and am also trying to keep up discussions with Park, Englebart, and SRI.

Attached please find a recent white paper of mine. I'm not addressing hypertext systems specifically very much, although the implications should be apparent. Nor am I addressing much the earlier portions of my SRI presentation about the broader PCP program and goals, although those connections should also be apparent. What this really is is an explication of the latter portions of my SRI presentation, slides 21-29, beginning with "Towards Portable, Robust Knowledge Environments".

I hope you find it relevant and useful. . .

In this brief white paper we define semantic hyperwebs as labeled, weighted, directed hypergraph-theoretical structures similar to weighted conceptual graphs; propose them as a canonical framework for representation of knowledge and semantic information in Distributed Knowledge Systems; and discuss technologies to support implementation. We are hopeful that such structures and implementations will be useful in the development of robust, portable environments for knowledge management, development, elicitation, and exchange. This paper is being distributed for comment, and not intended to be comprehensive, nor even especially novel. Rather we hope to solicit guidance from the community and help point the way to hopefully help develop and/or integrate off-the-shelf technologies which can be brought to bear on the problem at hand.
