Abstract:
An intelligent system reasons about--controls, explains,
learns about--its actions, thereby improving its efforts to achieve
goals and function in its environment. In order to perform
effectively, a system must have knowledge of the actions it can
perform, the events and states that can occur, and the relationships
among instances of those actions, events, and states. The BB*
environment represents this knowledge in an abstraction hierarchy and
defines uniform standards of knowledge content and representation for
modules within each of three hierarchical levels: architecture,
framework, and application.
The speaker will illustrate BB* with some of its current modules: (a)
the BB1 blackboard control architecture; (b) the ACCORD framework for
arrangement-assembly tasks; and (c) several domain-specific
applications of BB1-ACCORD. BB* advantages for system representation
and performance, system design and implementation, reusable knowledge
modules, and open systems integration will be discussed.
