Automatic Knowledge Acquisition for Expert Systems

The purpose of this article is to summarize the state-of-the-art of the expert systems research field. First, we introduce the basic notion of knowledge, and specifically of shallow knowledge, and deep knowledge. The first section of the document summarizes the history of the field. We analyze the differences between the first generation of expert systems, based primarily upon rulebased and fra...

Toward normative expert systems: Part II. Probability-based representations for efficient knowledge acquisition and inference.

We address practical issues concerning the construction and use of decision-theoretic or normative expert systems for diagnosis. In particular, we examine Pathfinder, a normative expert system that assists surgical pathologists with the diagnosis of lymph-node diseases, and discuss the representation of dependencies among pieces of evidence within this system. We describe the belief network, a ...

Knowledge Acquisition for Decision-theoretic Expert Systems

In this paper, the construction of decision-theoretic expert systems in collaboration with domain experts is discussed. In particular, the role of domain models in guiding the knowledge-acquisition process is reviewed, and various techniques that may help in the design of a decision-theoretic expert system are presented. Treatment planning in patients with a congenital heart disease is describe...

Inductive Knowledge Acquisition for Rule-Based Expert Systems

The RL program was developed to construct knowledge bases automatically in rule-based expert systems, primarily in MYCIN-like evidence-gathering systems where there is uncertainty about data as well as the strength of inference, and where rules are chained together or combined to infer complex hypotheses. This program comprises three subprograms: (1) a program that learns confirming rules, whic...
