Abstract

This paper discusses the characteristics of medical reasoning and shows the representation of these diagnostic models by the use of rough set theory. The key ideas are both a variable precision rough set model, which corresponds to an ordinal positive reasoning, and an upper approximation of a target concept, which corresponds to a focusing procedure. Acquired representation suggests that rough set model should be closely related with medical diagnosis.
