This research brief describes work documented in Evaluating Expert System Tools: A Framework and Methodology (R-3542-DARPA) and Evaluating Expert System Tools: A Framework and Methodology — Workshops (N-2603-DARPA).

This research brief describes a framework and methodology for evaluating software tools for use in developing expert systems. The framework calls for identifying (1) application characteristics, (2) the contexts in which the tool is to be used, (3) the tool's capabilities, (4) metrics for evaluating the tool, and (5) ways to apply the metrics to the tools. The research team's discussion with tool builders and users revealed the pivotal place of software engineering in expert system development.
