Removing the domain knowledge from an expert system leaves an _____.

  • A.explanation facility, which is the component that reports how a conclusion has been reached
  • B.expert system shell
  • C.inference network of the kind PROSPECTOR used to combine geological evidence into an estimate
  • D.empty working memory

Answer: B

What remains is the shell: engine, explanation facility, working memory and authoring tools, ready to receive a different domain's knowledge. EMYCIN was produced from MYCIN in exactly this way and showed that the architecture rather than the medicine was the reusable asset. The other options name a specific system's uncertainty machinery, a transient state and a single component.
