The Ontological Structure of a Troubleshooting System for Electronic Instruments

There is a great need for methodologies to simplify the knowledge engineering process. In this paper we describe a knowledge engineering methodology called ontological analysis. Ontological analysis aims at a step-by-step articulation of the knowledge structures necessary for performing a task by following the objects and relationships that occur in the task domain itself. As an example, we present an ontological analysis of the inference engine from a knowledge-based troubleshooting system for electronic instruments.
