Are Normative Expert Systems Appropriate for Diagnostic Pathology?

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 reas...

DDES: Dyeing diagnostic expert system for the textile coloration

Toward normative expert systems: Part I. The Pathfinder project.

Pathfinder is an expert system that assists surgical pathologists with the diagnosis of lymph-node diseases. The program is one of a growing number of normative expert systems that use probability and decision theory to acquire, represent, manipulate, and explain uncertain medical knowledge. In this article, we describe Pathfinder and our research in uncertain-reasoning paradigms that was stimu...

Knowledge refinement in diagnostic expert systems

This paper presents a new methodology for the incremental refinement of a knowledge base consisting of inductive rules. The novelty of the approach resides in the use of a body of deep knowledge for guiding the process of rule refinement, even in case this deep knowledge is too complex or not specific enough to deductively generate classification rules. Justifications derived from the deep know...

Diagnostic expert systems for defects in forged parts

This paper describes the development of a diagnostic expert system that identifies the cause of various manufacturing defects in hot forging and suggests remedies. The patterns of defect generation are various and due to many possible causes. They depend on part designs, tool designs and process conditions. Pertinent factors include part shape, the state of lubrication, location of the performe...
