Knowledge modeling of program supervision task and its application to knowledge base verification
This paper presents a knowledge-level analysis of the program supervision task based on two different systems: PEGASE and PULSAR. A knowledge-level analysis of a knowledge-based system reveals the organisation of the knowledge it uses and how it uses this knowledge to solve the task. It is also the key to determine the properties that it assumes about domain knowledge. These aspects of knowledge-level analysis have been successfully used as a framework to compare different systems, mostly for knowledge engineering purposes. This paper also describes how domain knowledge assumptions have been exploited in the implementation of a verification module for program supervision knowledge bases.
