Presentation of Medical Knowledge by Arden Syntax with Extensions Based on Fuzzy Set Theory

摘要

The Arden Syntax for Medical Logic Systems (Arden) is an approach to present medical knowledge by defining rules that include crisp decision logic. Clinical rules based on natural language usually contain uncertainty by way of vagueness which cannot be handled by Arden. Uncertain knowledge can be presented by extending Arden to include concepts of fuzzy set theory.
