  • Patent number: 5208899
    Abstract: Method and apparatus are provided for use in a frame-based semantic network wherein at least one specialization slot-control frame defining a specialized behavior is linked to a base slot-control frame defining a global behavior in a hierarchical data structure. Slot behavior is attached to an occurrence of the slot in any other frame such that the slot and its behaviors are inherited to related frames as a unit. All specialized behaviors are compiled into a compact internal format and stored in a reserved space in the slot-control frame. The method and apparatus have particular utility in knowledge-based or expert systems.
