Annotating Ontologies with Descriptions of Vagueness

Vagueness is a common linguistic phenomenon manifested by predicates that lack clear applicability conditions and boundaries such as High, Expert or Bad. The usage of vague terminology in ontology entities can hamper the latter’s quality, primarily in terms of shareability and meaning explicitness. In this paper we present the Vagueness Ontology, a metaontology that enables the explicit identification and description of vague entities and their vagueness-related characteristics in ontologies, so as to make the latter’s meaning more explicit.
