A knowledge base system includes separate expert user and end user interface facilities which communicate with the system\s inference engine and knowledge base. Linking means operatively interconnect the expert user facility to the end user interface facility enabling the simulation of the end user environment while the knowledge base is being concurrently edited or modified. Such simulation is carried out by placing the end user interface facility in an edit mode of operation during which the user can stop at any point. In response to a single keybgoard command, an expert user can switch control back to the expert user facility to a point within the knowledge base selected relative to the context of the operation which was being run thereby facilitating the maintenance and updating of the knowledge base.

An expert system which includes a knowledge base comprising a memory for storing knowledge including data representative of facts organized into frames and rulesets linked to said frames so as to create decisions using a premise-conclusion if-then form of reasoning and a programmed computer which includes an inference engine coupled to said memory for interpreting said rulesets using said if-then reasoning, said system further including: expert user interface facility means coupled to said inference engine and to said knowledge base for generating commands to edit and update said knowledge base and for designating at least one point within said knowledge base where editing can take place; end user interface facility means coupled to said inference engine for communicating and receiving commands from said inference engine, said end user interface facility means when operating in a predetermined mode of operation controlling the operation of said expert system and receiving input information from said inference engine indicative of the context of an operation being performed; and control means coupled to said end user facility means and said expect user interface facility means for enabling said expert user interface facility means to switch control from said and user interface facility means to said expert user interface facility means to said one point when said end user interface facility means is operating in said predetermined mode of operation and as a function of said input information received by said end user interface facility means.
