Knowledge Representation and Reasoning

Knowledge Representation (KR) is crucial in AI, allowing for the encoding and manipulation of information. The chapter discusses logic-based representations, focusing on Propositional and First-Order Logic, as well as Ontologies and Semantic Networks. These methods help create intelligent systems capable of reasoning and making informed decisions in complex domains.

    Ontologies

    An ontology is a formal framework for organizing knowledge, defining concepts, relationships, and constraints within a specific domain.
