Definition

A knowledge-based system is a computer program that uses a knowledge base with an inference engine in order to solve problems that usually require significant specialized human expertise. It embodies the problem-solving knowledge of a human expert in a narrowly defined domain and it is able to extend that body of knowledge through its inference engine or query system.

Characteristics

People who possess specialized knowledge of a particular domain are called experts. This knowledge may take the form of a set of rules or heuristics about how to deal with particular circumstances and problems. Expert knowledge can be embodied in a computer through techniques of knowledge acquisition, knowledge representation, and knowledge engineering: a knowledge baseis a collection of such knowledge. Knowledge-based systems combine a knowledge base with automated inference mechanisms: they replicate the cognitive processes that are employed by experts when solving...
