Expert system shells: very‐high‐level languages for Artificial Intelligence
Harold Boley · Expert Systems · 1990
Abstract: Expert system shells are discussed as very‐high‐level programming languages for knowledge engineering. Based on a category/domain distinction for expert systems the concept of expert system shells is explained using seven classifications. A proposal for a shell‐development policy is sketched. The conclusions express concern about current over‐emphasis on graphical interfaces.
