What role does the knowledge base play in an expert system?

• A. It allows user input to be easily processed
• B. It stores rules and information from human experts
• C. It retrieves data from various sources
• D. It executes commands linked to user actions

Answer: (B)

The knowledge base is a fundamental component of an expert system primarily because it is where all the relevant rules and information gathered from human experts are stored. This structured repository allows the system to simulate human expertise in specific domains by providing it with the necessary data to make informed decisions and solve problems. By incorporating knowledge from multiple experts, the knowledge base enables the system to effectively process queries and generate solutions or recommendations based on established facts and rules. The role of the knowledge base is critical; without it, the system would lack the foundational information required to function as an expert advisor. It acts as the core that informs the inference engine, which applies logical processes to reason through the stored rules and make conclusions.
