An inference engine is a component of an expert system that uses the knowledge base to make decisions. The inference engine uses a logical process to apply the rules to the knowledge base and generate a response.

The logical process used by the inference engine varies depending on the expert system. However, the standard logical process used by all inference engines includes the following steps:

  1. The inference engine starts by reading the knowledge base.
  2. The inference engine applies the rules to the knowledge base.
  3. The inference engine generates a response.

The response generated by the inference engine can be advice, a diagnosis, or a decision.

Inference engines are used in a variety of expert systems, including: Medical diagnosis systems Financial intelligence systems, Engineering systems

Inference engines are a valuable tool for artificial intelligence. They allow expert systems to make rapid and complex decisions and can be used in various applications.
