LIMES: a hypertext interface to a cholesterol management expert system

摘要

Hypermedia representations add superior explanation facilities and user interfaces to expert systems. LIMES (LIpid Management Expert System) is a hypermedia cholesterol management application built on the HyperLipid Advisory System created on the Macintosh II at Stanford University. HyperLipid is an expert system which was designed to administer the National Cholesterol Education Program clinical algorithm for detecting and treating hyperlipidemia. LIMES executes the HyperLipid knowledgebase within a HyperCard stack which embeds the inference engine of the expert system. The HyperCard module serves initially as a programming tool to communicate with the rule development system and ultimately as the interface to the runtime application. Predictors of the utility of this and other systems are the expertise differential between the system and end user, and the degree of risk inherent in the domain.
