What is Inference Engine

Inference engine is one of the basic components of an expert system that carries out reasoning whereby the expert system reaches a solution. It matches the rules provided in the rule base with the facts contained in the database.

The part of a decision support system that performs the reasoning function.

An inference engine is a computer program that applies artificial intelligence to try to obtain answers or responses to queries from a knowledge base.

The component of a CDSS program that formulates inferences from a knowledge repository.

A computer program that tries to derive answers from a knowledge base.

The part of an expert system that actually performs the reasoning function.

An Inference Engine is a tool from artificial intelligence. The first inference engines were components of expert systems. The typical expert system consisted of a knowledge base and an inference engine. The inference engine applied logical rules to the knowledge base and deduced new knowledge. Inference engines work primarily in one of two modes: forward chaining and backward chaining. Forward chaining starts with the known facts and asserts new facts. Backward chaining starts with goals, and works backward to determine what facts must be asserted so that the goals can be achieved.
