本体（Ontology）
In computer science, an ontology is the product of an attempt to formulate an exhaustive and rigorous conceptual schema about a domain. An ontology is typically a hierarchical data structure containing all the relevant entities and their relationships and rules within that domain (eg. a domain ontology). The computer science usage of the term ontology is derived from the much older usage of the term ontology in philosophy.
