A mereotopological semantics to manage ontologies is presented. The aim is to provide a formal basis for ontology cleaning. It allows us to arrange, in a consistent manner, the concepts in early steps of the building of an ontology as well as to repair anomalies. The semantics supports cleaning cycle that combines several AI techniques as closed world assumption, default reasoning on taxonomies and knowledge acquisition.
