The quality of ontologies (QoO) is increasingly becoming a research issue on the Semantic Web. Ontology users may have difficulties locating the proper concepts in large ontologies, due to low quality. To quantify these problems, we use the notion of naturalness. In this paper we evaluate several existing important ontologies (WordNet, UMLS, etc.) to get numeric measures of naturalness. We concentrate on the question to what degree concept pairs connected by IS-A relationships are natural and therefore comprehensible to users.
