Describing Reusable Problem - Solving Methods with aMethod

To reuse a problem-solving method, a knowledge engineer must know the assumptions about the structure of the knowledge roles inherent to the method. We construct a method ontology in order to formalize these assumptions. This ontology deenes the roles played by the knowledge in the inference process, and serves as an interface for the knowledge engineer to evaluate if an application domain conf...

Task Modeling with Reusable Problem-Solving Methods

Problem-solving methods for knowledge-based systems establish the behavior of such systems by de ning the roles in which domain knowledge is used and the ordering of inferences. Developers can compose problem-solving methods that accomplish complex application tasks from primitive, reusable methods. The key steps in this development approach are task analysis, method selection (from a library),...

The Reusable Symbol Problem

Examining the major differences between how traditional programs compute and our current understanding of how brains compute, I see only one key gap in our ability to carry out logical reasoning within neural networks using standard methods. I refer to this gap as the reusable symbol problem: How can neural systems use multiply-instantiatable symbols to represent arbitrary objects? This problem...

Reusable Frameworks of Problem Solving

We motivate the use of Problem-Solving Methods (PSM) in order to realize reusable knowledge models. The notion of PSM is extended to Frameworks of Problem Solving (FPS), thus giving PSM a larger generality and enable specialization or update of PSM during system development. An example of a FPS in the context of a project dealing with model-based diagnosis illustrates the approach. Finally, we ...
