Expert System Shell
A software package that facilitate the building of knowledge-based systems by providing a knowledge representation scheme and an inference engine. The developer adds domain knowledge.

"Jess [Java Expert System Shell] is a rule engine and scripting environment written entirely in Sun's JavaTM language by Ernest Friedman-Hill at Sandia National Laboratories in Livermore, CA.
The few remaining expert system shell companies were eventually forced to downsize and search for new markets and software paradigms, like case based reasoning or universal database access.
Figure 3 above shown the architecture of Leonardo expert system shell. This architecture was used Negnevitsky, M. (1998) to develop expert system for teaching fault analysis. According to Negnevitsky, M.
They also created the first expert system shell, that contained the inference engine, which contained the logic of how rules were to be applied. MYCIN could also deal with probabilistic rules, which DENDRAL couldn't.

That person simply has to understand both what he wants a computer to do and how the mechanism of the expert system shell works. It is this shell, part of the inference engine, that actually tells the computer how to implement the expert's desires.
