Ontology papers should be around 6–8 pages (in Elsevier double column format).
These should be short, descriptive papers, the purpose of which is to present all facets of a significant and re-usable ontology resource. These can include:
the process of creating, modeling, learning and/or extracting the ontology;
important properties of the ontology;
how ontology developers and/or users benefited from Semantic Web Technologies; and
example use cases (we particularly encourage papers describing ontologies that are already deployed in the real world).
To foster this, we strongly prefer openly accessible ontologies to support the reuse of the resource by the research community.
Ontologies themselves may be written in any formalism, bearing in mind the aim to support reuse.
