What is an Ontology ?

In contrast to a traditional KOS such as thesauri, ontologies provide conceptual abstraction and differentiated relationships. Ontologies specifically separate concepts from terms and thereby better reflect the structure of human understanding of a domain. In ontologies, the semantics are developed through ensuring that each concept within the domain is uniquely and precisely defined and by specifying elaborated relationships among the concepts. The relationships in an ontology are explicitly named and developed with the specification of rules and constraints so that they reflect the context of the domain for which the knowledge is modelled.
