Title

Combining factual and heuristic knowledge in knowledge acquisition

Source

Telematics and informatics. 9(1992) nos.3/4, S.297-311

Year

Abstract

Describes a knowledge acquisition technique that combines heuristic and factual knowledge represented as 2 hierarchies. Theses ideas have been applied to the construction of a knowledge acquisition interface to OPERA (Expert System Analyst). The goal of OPERA is to improve the operations support of the computer network in the space shuttle launch processing system. The knowledge acquisition bottleneck lies in gathering knowledge from human experts and transferring it to OPERA. OPERA's knowledge acquisition problem is approached as a classification problem- solving task, combining this approach with the use of factual knowledge about the domain. The interface has been implemented in a Symbolics workstation, making heavy use of windows, pull down menus, and other user-friedly devices
