β¦ Synopsis
SALT is a knowledge-acquisition tool for generating expert systems that can use a propose-and-revise problem-solving strategy. The SALT-assumed method incrementally constructs an initial design by proposing values for design parameters, identifying constraints on design parameters as the design develops and revising design decisions in response to detection of constraint violations in the proposal. This problem-solving strategy provides the basis for SALT's knowledge representation. SALT guides its interrogation of the domain expert using its identification of weaknesses in the knowledge base.
