The unique name assumption is a simplifying assumption made in some ontology languages and description logics. In logics with the unique name assumption, different names always refer to different entities in the world. The standard ontology language OWL does not make this assumption, but provides explicit constructs to express whether two names denote the same or distinct entities.〔(OWL Web Ontology Language Reference )〕 * owl:sameAs is the OWL property that asserts that two given names or identifiers (e.g., URIs) refer to the same individual or entity.* owl:differentFrom is the OWL property that asserts that two given names or identifiers (e.g., URIs) refer to different individuals or entities.==See also== * Closed-world assumption * Coreference 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Unique name assumption」の詳細全文を読む スポンサード リンク
