Utilizing Knowledge: The Components of the SB-ONE Knowledge Representation Workbench

SB-ONE is a knowledge representation workbench specifically designed for the construction and exploitation of conceptual knowledge bases in natural language systems. At the heart of the system lies the SB-ONE language, which allows for the representation of conceptual knowledge and simple existential assertions. The kernel language has been extended by “metastructures,” which permit the description of objects in a represented domain both as individuals and as pairs of a relation. Knowledge can be assigned to partitions, which may themselves be ordered in inheritance hierarchies. The construction of SB-ONE knowledge bases is facilitated by functional, textual, and graphics-based interfaces; a consistency maintenance system for the syntactic well-formedness of SB-ONE knowledge bases; a classifier; and a realizer. Additional utilities operating on SB-ONE that are briefly described include a pattern matcher, a spreading-activation mechanism, an interpreter and classifier for SB-ONE to SB-ONE translation rules, an integration mechanism for an external frame-based representation, and a connection between SB-ONE and an extended PROLOG.
