Annotation Classes: A Structuring Mechanism for OWL Ontologies.
Mike Dean · 2008
Abstract. OWL provides AnnotationProperties as a means of providing extralogical information about ontologies, classes, properties, and individuals. We propose analogous AnnotationClasses as a means of adding hierarchical or other structure to an ontology without additional entailments, primarily for the benefit of human users. We use the RadLex vocabulary as a motivating example and also address the more general problem of understanding OWL ontologies.
