An Explanation Facility for the ROSIE Knowledge Engineering Language
"This report describes the design and implementation of an explanation facility for the Rule-Oriented System for Implementing Expertise (ROSIE) knowledge engineering language, an expert system building environment developed at The RAND Corporation. An explanation facility is critical in the construction and utilization of an expert system, since it provides the mechanisms by which the expert system can explain its performance. These mechanisms typically show the user (1) why and how the expert system reached a given conclusion, (2) why the system asked for particular information, (3) how rules and data got added to the knowledge base, (4) what is the purpose of a rule or ruleset, and (5) why the use of a rule is justified."--Rand abstracts.
