FT> No Jim, you did not understand me correct. I am only referring to one
particular project where we try to use agent technology to do something in
our field of research that seems somewhat of track. In our definition a
virtual actor is an technological implementation of a human actor (like an
architect, structural engineer, building advisor, and such), and a virtual
actor consists of a rather large number of
agents each performing one of the roles of the (virtual) actor.

> And by "technology" do you mean using some human-fabricated mechanism?

FT>No, by technology I mean agent technology, i.e. the concepts, models and
tools used to create multi agent systems.

FT>So if you were able to create a monster and call it Frankenstein youre
name probably would not be Odell ;-/

FT>What we call virtual actors you call agents, compound agents, complex
agents, or whatever. To me 'agent' is a word mostly connected to the ICT
world (travel agents do not play a role in our field). So we prefer Virtual
Architect, Virtual Building Advisor, and such because that clearly displays
the performances required.
Moreover, there is not really a reason why a travel agent would not be
called an actor or, a virtual actor if the roles of the actor are performed
by some multi agent system. Or is there?
