Abstract

The use of uncertainty in a rule-based expert system for the analysis of chest pain is discussed. The system, EMERGE, has been evaluated retrospectively and prospectively and has been found to perform extremely well. The original system has been altered to handle degrees of presence of symptoms and variable contribution of antecedents. It also utilizes a logical construct which generalizes traditional AND/OR logic.
