What term describes models that capture and automate expert procedures within a domain?

• A. Expert Systems
• B. Symbolic AI
• C. AGI
• D. Markov Chains

Answer: (A)

Expert systems are AI programs designed to capture the knowledge and decision-making procedures of human experts in a specific domain and automate them. They typically combine a knowledge base, which stores facts and rules about the domain, with an inference engine that applies those rules to user input to generate conclusions or recommendations. This combination lets the system mimic expert reasoning to solve problems and guide actions without a human present.

Symbolic AI is a broader approach that uses symbols and logic to represent knowledge and perform reasoning; expert systems often use this kind of reasoning, but the term “expert system” specifically refers to a system built to codify and automate the procedures an expert would follow in one domain. AGI aims for general, across-the-board intelligence rather than domain-specific procedural replication, so it isn’t the best fit for describing models that capture expert procedures. Markov chains are probabilistic models focused on state transitions and probabilities, not the detailed codified procedures of domain experts.
