Abstract
The present invention provides a contextual editor for an expert system. The editor leads the operator through a series of screens which designate classes of information, logical nodes, and the interrelation of the nodes. The screens are so arranged that they prevent the operator from providing classes or nodes with logically insufficient information. At the end of each definition the screen automatically shows a logical tree which graphically illustrates the logical interconnection between the nodes. The editor provided by the present invention provides the knowledge base developer with a guided knowledge entry system that modifies its behavior based on the context of the knowledge structures being entered. This approach not only facilitates the creation of the rules base knowledge, but also frequently prevents the user from entering invalid values or logic structures. Also, the guided editing approach allows the developer to learn and use the system much more quickly, thus becoming productive much sooner.
