Questions tagged [knowledge-base]

For questions related to the concept of a knowledge base, which is a set of sentences (or propositions), which are, for example, used to implement knowledge-based intelligent agents. Each sentence represents some assertion about the world. Sentences that are not derived but are given as true are sometimes called axioms. We can perform inference to derive new facts given the sentences in the knowledge base.
