Components of expertise for knowledge level modeling

Abstract

A new dimension of object-oriented components is presented to describe knowledge-level models of an application. From the knowledge-level perspective, components are needed for modeling the problems, solution methods, and their relationships in a problem-solving process. A problem can often be decomposed recursively by various methods into subproblems until reaching primitive ones. Each primitive problem is confined to a simple computational task, which can be solved by one problem-solving method. The process of problem solving is viewed as a modeling activity through explicitly represented knowledge-level models that are, then, operationalized. Design issues that are encountered when developing such a component-based framework for knowledge-level modeling are described.<>
