Knowledge representations and interfaces in financial expert systems

The paper concerns itself with two related themes: explanation and knowledge reuse. They are treated in the context of the two ideas in the title, essential components of any knowledge-based system: interfaces and knowledge representation. The themes are related because they both require explicitness of knowledge; implicit knowledge makes for poor explanations, and restricts the potential for reuse. The paper describes the approach to graphical explanation and knowledge reuse. It describes the approach to graphical explanation taken. It leads, by way of considering the generality of the approach, to a consideration of aspects of knowledge reuse and a framework in which it may be realised
