This survey provides a conceptual introduction to ontologies and their role in information systems and AI. The authors also discuss how ontologies clarify the domain's structure of knowledge and enable knowledge sharing. The authors point to the somewhat different roles ontologies play in information systems, natural language understanding, and knowledge-based systems.

Ontology as vocabulary

Ontology as content theory

Why are ontologies important?

Ontological analysis clarifies the structure of knowledge. Given a domain, its ontology forms the heart of any system of knowledge representation for that domain. Without ontologies, or the conceptualizations that underlie knowledge, there cannot be a vocabulary for representing knowledge. … Second, ontologies enable knowledge sharing.
