Extraction of common conceptual components from multiple ontologies
  Understanding large ontologies is still an issue, and has an impact on many
ontology engineering tasks. We describe a novel method for identifying and
extracting conceptual components from domain ontologies, which are used to
understand and compare them. The method is applied to two corpora of ontologies
in the Cultural Heritage and Conference domain, respectively. The results,
which show good quality, are evaluated by manual inspection and by correlation
with datasets and tool performance from the ontology alignment evaluation
initiative.
