Building a composite syntax for expert system shells

The authors examine the syntactic similarities and differences of five expert system shell production-rule languages. To help knowledge engineers manage information, they develop a composite production-rule syntax that provides a common language for defining production rules. The expert system shells are the: Integrated Reasoning Shell (TIRS); Expert System Environment (ESE), KnowledgeTool; Knowledge Engineering Environment (KEE); and Official Production System Version 5 (OPS5).
