TL;DR

It is hypothesised that knowledge engineering may be obviated, particularly in the long term maintenance of expert systems, if the rules experts provide are used in the context in which they are given.

Abstract

Knowledge engineering, obtaining knowledge from experts and incorporating it into expert systems is difficult and time consuming. We suggest that these difficulties arise because experts never report on how they reach a decision, rather they justify why the decision is correct. These justifications vary markedly with the context in which they are required, but in context they are accurate and adequate; the difficulties in knowledge engineering arise from taking the justification out of context. We therefore hypothesise that knowledge engineering may be obviated, particularly in the long term maintenance of expert systems, if the rules experts provide are used in the context in which they are given. This paper describes work in progress to test this hypothesis.

Deterministic rules are the simplest of the methodologies used in expert systems: the knowledge base contains the set of rules defining the problem, and the inference engine draws conclusions applying classic logic to these rules.

The proposal and the interaction problem call into question many generally held beliefs about expert systems such as the belief that the knowledge base should be separated from the inference engine.

The use of the Knowledge Dictionary is discussed to redevelop GARVAN-ES1, a medical expert system for the automatic clinical interpretation of laboratory reports, using the relational data model to store the heuristics in a data form rather than executable code form.

The analytical quality of immunoassays now exceeds the quality of the reference limits supplied to clinicians to assist diagnosis, and it is concluded that nationally or internationally defined reference limits would therefore provide more information at less cost than do individual laboratory reference limits.
