An expert system is a knowledge-based program that provides 'expert quality' solutions to problems in a specific domain (Luger & Stubblefield, 1989, p. 291). The power of an expert system (ES) is derived from presence of a knowledge base filled with expert knowledge, mostly in symbolic for...
The inference engine.This part of the system pulls relevant information from the knowledge base to solve a user's problem. It is arules-based systemthat maps known information from the knowledge base to a set of rules and makes decisions based on those inputs. Inference engines often include ...
Some years ago it was stated that knowledge acquisition is a major bottleneck in the development of expert systems (Feigenbaum & McCorduck, 1984), and this view is still propounded. Although it is...DOI: 10.1007/978-1-4613-9733-5_14 被...

Types of Expert System Technology Expert systems can be classified into five categories. There are several types of expert systems, including rule-based, frame-based, fuzzy, neural, and neuro-fuzzy. Simple expert systems that describe knowledge as a collection of rules are called rule-based expert...

We study the sequential information acquisition problem for rule-based expert systems as follows: find the information acquisition strategy that minimizes the expected cost to operate the system while maintaining the same output decisions. This problem arises for rule-based expert systems when the cost...
