What is a knowledge base in a logical agent?

  • A.The inference procedure the agent uses to draw conclusions
  • B.A record of the percepts the agent has received so far
  • C.A set of sentences expressing what the agent takes to be true
  • D.The set of all the sentences that can be written in the language

Answer: C

The knowledge base holds the sentences the agent has been told or has inferred, and the inference procedure answers questions against it. The language's sentences are the possibilities rather than the contents, procedures are separate, and percepts are one source among several. Separating what is believed from how conclusions are drawn is what allows a general reasoner to serve any domain, which is the founding architecture of the knowledge based approach.
