Re: [ontology-summit] Track on Cyc?

[Amanda Vizedom <amanda.vizedom@xxxxxxxxx>]

Jack,

Thanks for the alternate framing!  Yes, that's very much the spirit intended. While last year's summit was (atypically) focused on marketing, this year's isn't. This year, the project is much more about advancing understanding, sharing what we know and making collaborative steps to advance understanding at the intersections.  

I would only add that IMHO this stage is also preparation that makes some later-stages less adversarial and more productive. That is, going through this kind of information exchange and collaborative exploration can propel researchers to work on what industry actually needs, ontologists to understand better what systems engineers actually want and need, systems engineers to understand better what to expect from ontology and how to get what they want from it, and all parties to understand better how to talk to each other in order to communicate and get things done.

Amanda's suggestion lives in the spirit of a Bohmian Dialogue,
described by David Bohm in his book On Dialogue. The spirit has it
that all agendas are "checked at the door", that the conversation is
about information transfer in a congenial way.

In general, a Bohmian dialogue is used to set the stage for a later
agenda-laden conversation, where the participants first get to know
each other and talk about what they bring to the table without
advertising agendas. Real information transfer can take place in such
a non-adversarial environment.
