HEWLETT-PACKARD LABORATORIES COMPUTER COLLOQUIUM Speaker: Barbara Hayes-Roth Senior Research Associate Stanford Knowledge Systems Lab Subject: BB*: A modular and layered environment for AI systems Time: Thursday, May 14, 1987, 4 pm Place: Hewlett-Packard 5M Auditorium 1501 Page Mill Road Palo Alto Non-HP Employees: Welcome! Please come to the lobby shortly before 4 pm so that you can be escorted to the auditorium. Refreshments will be served following the talk. Host: Barry Bronson (857-3033) Stanford contact: Ted Kamins (kamins@sierra) 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. -------
