A Vague Sense Classifier for Detecting Vague Definitions in Ontologies

Vagueness is a common human knowledge and linguistic phenomenon, typically manifested by predicates that lack clear applicability conditions and boundaries such as High, Expert or Bad. In the context of ontologies and semantic data, the usage of such predicates within ontology element definitions (classes, relations etc.) can hamper the latter’s quality, primarily in terms of shareability and meaning explicitness. With that in mind, we present in this paper a vague word sense classifier that may help both ontology creators and consumers to automatically detect vague ontology definitions and, thus, assess their quality better.
