  • Title: Validating the knowledge base of a therapy planning system.
    Author: Shwe MA, Tu SW, Fagan LM.
    Journal: Methods Inf Med; 1989 Jan; 28(1):36-50. PubMed ID: 2704300.
    Abstract:
    Validation of expert system knowledge bases has proved to be difficult. This paper presents a description of a system called ScriptGen that generates test data for validating the knowledge base of the ONCOCIN cancer therapy planning system. Because of the size and complexity of the ONCOCIN knowledge base, we require tools for automated validation. ScriptGen, which applies techniques developed in testing both traditional software and expert systems, uses a parallel model of the ONCOCIN knowledge base and its own inference engine to generate test cases. We derived the limits of the system from a study that seeded errors into an existing knowledge base.
