Quality of Expert Systems: Methods and Techniques (Kwaliteit van Expertsystemen: Methoden en Technieken).

摘要

This report is the result of the second phase of the technology project 'Quality of Expert Systems', carried out under commission of the Ministry of Defence, Director Defence Research and Development. Participants in the project are TNO Physics and Electronics Laboratory (FEL-TNO), University of Limburg (RL) and the Research Institute for Knowledge Systems (RIKS). Based on (FEL1989-148) this report examines more thoroughly the problems that are related to the quality of expert systems. Firstly a method is presented which views the development of expert systems as a (parallel) activation of modelling processes. Secondly the conceptual similarities between databases and knowledgebases are stressed. As an implication of this the use of Nijssens Information Analysis Method as a knowledgebase specification method is proposed. Thirdly the modularity and structure of knowledge bases is examined, together with the applicability of conventional testing methodologies in expert systems. Lastly it is demonstrated with an example that the integration of database theory and artificial intelligence signifies a step in the direction of a better quality control of expert systems.
