Ontologies
Ontologies are formal, explicit specifications of shared conceptualizations, used to represent knowledge about a domain in a structured and machine-readable way. They define concepts, properties, relationships, and constraints to enable consistent understanding and reasoning across systems, often in fields like artificial intelligence, semantic web, and data integration.
Developers should learn ontologies when working on projects requiring semantic interoperability, such as building knowledge graphs, implementing linked data, or developing intelligent systems that need to reason about complex domains. They are essential for standardizing data models in healthcare, e-commerce, or scientific research to ensure data consistency and enable advanced querying and inference.
