"Knowledge Engineering Environment KEE KEE from Intellicorp is the most widely used of the high-end expert system development shells. It is available on Symbolics, Xerox and Texas Instruments Artificial Intelligence workstations, Apollo, DEC and Sun workstations, DEC VAX mini computers and 80386-based IBM PC-compatible computers. It provides a powerful and sophisticated development environment, offering hierarchical object representation of data and rules, partitioning of the rulebase, an inference engine providing agenda-driven chaining in addition to backward and forward chaining, and a Truth Maintenance System for what-if and assumption-based reasoning. It offers a suite of development tools, such as specialized structured editors and several methods to build the data structures, including menus and an English-like construction language. A sophisticated graphics toolkit allows the creation of user interfaces which can be directly driven by the data values in the knowledge base."
