This report describes an investigation into the comparative merits of eight knowledge engineering tools: EMYCIN, KAS, EXPERT, OPS5, ROSIE, RLL, HEARSAY-III, and AGE. These tools are very-high-level programming languages designed for building expert systems, i.e., programs that embody the expertise of specialists or scholars in some problem area. All eight of the tools were applied to the same environmental crisis management problem, involving the creation of an online assistant to aid in locating and containing an oil or hazardous chemical spill at the Oak Ridge National Laboratory. The models produced by these tools are described and used to compare the effectiveness of each tool for building expert computer systems.
