Ontologies now play an important role for many knowledge-intensive
applications for which they provide a source of precisely defined terms. However,
with their wide-spread usage there come problems concerning their proliferation.
Ontology engineers or users frequently have a core ontology that they
use, e.g., for browsing or querying data, but they need to extend it with, adapt it
to, or compare it with the large set of other ontologies. For the task of detecting
and retrieving relevant ontologies, one needs means for measuring the similarity
between ontologies. We present a set of ontology similarity measures and a
multiple-phase empirical evaluation.
