Knowledge acquisition by the domain expert using the tool HEMATOOL

Abstract

The commercial expert system tools do not provide enough support for knowledge base construction and maintenance with respect to KA tools provided. HEMATOOL provides an easy way to overcome some of the problems of KA and knowledge base maintenance. HEMATOOL allows the domain expert to concentrate on various parts of the domain, e.g. parameters, one at a time. As new knowledge becomes available, the expat is in the position to maintain, to a certain extent, the knowledge base. However, in some situations the knowledge engineer will be still be required to render assistance. HEMATOOL is a prototype system which is currently being evaluated.

In this paper we suggest an Object-Oriented approach towards KB modelling. Not all the domains are best modelled by the OO paradigm. The applicability of this approach, therefore, depends on the nature of the knowledge in the domain.
