Typically, an expert system consists of three main components:
Knowledge Base: This includes the domain-specific knowledge, facts, and rules. In the context of cancer, this would involve data from medical research, clinical trials, and case studies. Inference Engine: This is the core algorithm that applies the rules to the known facts to deduce new facts. It is responsible for the reasoning process. User Interface: This allows users to interact with the system, input data, and receive outputs or recommendations.
