Enhanced User Interfaces for Diagnostic Expert Systems

The acceptance of a knowledge-based system by the end user has been regarded as one of the major criteria for its success. The user interface design is one of the main reasons that hindered knowledge-based systems transition from prototype to everyday use. The success of knowledge-based systems therefore depends on the user interfaces as well as the efficiency of its knowledge encoding and reasoning. In this paper the problems encountered in the currently applied user interfaces of knowledge based systems are discussed, and a number of enhancements are introduced for designing diagnostic expert system user interfaces.
