ABS1RACT The paper presents an approach to the automation of knowledge acquisition for expert systems. The approach is based on several general principles emerging from the field of machine learning: expert system building as a three phase process, understanding-based knowledge extension, knowledge acquisition through multistrategy learning, consistency-driven concept formation and refinement, ...

In this paper we point out the reasons that lead us to distribute modular applications and how we distribute them. We illustrate our ideas with an example of expert system shell.

Current expert systems cannot properly handle imprecise and incomplete information. On the other hand, neural networks can perform pattern recognition operations even in noisy environments. Against this background, we have implemented a neural expert system shell NEULA, whose computational mechanism processes imprecisely or incompletely given information by means of approximate probabilistic re...

An expert system shell (SYSTEM Z-II) based on fuzzy logic and numbers was built in a minicomputer environment. Z-II wss proved to be a successful and powerful expert system building tool because it can handle both exact and inexact reasoning. Its third generation, Z-III, is developed in a PC environment and includes some new enhancement features compared to Z-II. In this paper, the development ...

AGNESS is an expert system shell developed at the University of Minnesota. AGNESS is more general than other shells. It uses a computation network to represent expert defined rules, and can handle any well-defined inference method. The system works with non-numeric as well as numeric data, and shares constructs whenever possible to achieve increased storage efficiency. AGNESS uses a menu-driven...

Abstract: The state has multiple interests in the quality of bail decisions. Previous papers (Hassett, 1991, 1990) explored the issue of whether computer technology, specifically expert systems technology, could contribute to improving the quality of pretrial release / detention decisions. Subsequently a prototype expert system which makes bail recommendations was developed using the XiPlus exp...

An approach to decision making that integrates multi-attribute decision techniques with expert systems is described. The approach is based on the explicit articulation of qualitative decision knowledge which is represented by a tree of attributes and decision rules. The decision making process is supported by a specialized expert system shell for interactive construction of the knowledge base, ...
