    ABSTRACT:: BB1 implements a domain-independent "blackboard control
               architecture" for Al systems that control, explain, and learn
               about their own problem-solving behavior. A BB1 system
               comprises: a user-defined domain blackboard, a pre-defined
               control blackboard, user-defined domain and control knowledge
               sources, a few generic control knowledge sources, and a
               pre-defined basic control loop. The architecture's run time
               user interface provides capabilities for: displaying the
               blackboard, knowledge sources, and pending knowledge source
               actions, recommending an action for execution, explaining a
               recommendation, accepting a user's override, executing a
               designated action, and running without user intervention. BB1
               supports a variety of control behavior ranging from execution
               of pre-defined control procedures to dynamic construction and
               modification of complex control plans during problem solving.
               It explains problem-solving actions by showing their roles in
               the underlying control plan. It learns new control heuristics
               from experience, applies them within the current
               problem-solving session, and uses them to construct new
               control plans in subsequent sessions.
