This podcast reviews the role and importance of ontologies, particularly in the context of Large Language Models (LLMs) and the Semantic Web. It highlights how ontologies complement and augment LLMs, addressing their limitations and improving the accuracy and traceability of their outputs. The document also explores the technical aspects of ontologies, focusing on RDF (Resource Description Framework) and OWL (Web Ontology Language) as key standards for representing and utilizing ontological knowledge.
