Ontology-Based Information Systems

Abstract

An ontology is model of (some aspect of) the world - it introduces vocabulary relevant to the domain and specifies the meaning (or semantics) of this vocabulary. For example, an anatomy ontology might introduce terms for kinds of object, such as Heart, Vein, Artery, and so on, as well as terms for relationships between objects, such as isPartOf, isConnectedTo, isCausedBy, and so on. The meaning of each term is specified by combining other terms using some formal language, typically a logic.
