A semiautomated methodology for knowledge elicitation

A semiautomated methodology for eliciting knowledge from an expert is described. The methodology suggests the use of a manual interview technique and the application of a machine learning program to structure the elicited information. This way the experts are free to express their knowledge in a familiar format. Automated processing helps the knowledge engineer formalize knowledge.
