SALT provides a knowledge acquisition framework for the development of expert systems that use propose-and-revise as their problem-solving method. These systems incrementally construct a tentative design, identify constraints on the design and revise design decisions in response to constraint violations. By having an under-standing of the specific problem-solving method used to integrate the knowledge it acquires, it has been previously shown that SALT possesses a number of advantages over less restrictive programming languages. We have applied SALT to a new type of propose-and-revise task, and have identified areas where SALT was too restrictive to adequately permit acquisition of domain knowledge or efficient utilization of that knowledge. Addressing these problems has led to a more “general” SALT and to a better understanding of when it is an appropriate tool.
