  This work is done as part of a master's thesis project. The goal is to
integrate two or more ontologies (of the same or close domains) in a new
consistent and coherent OWL ontology to insure semantic interoperability
between them. To do this, we have chosen to create a bridge ontology that
includes all source ontologies and their bridging axioms in a customized way.
In addition, we introduced a new criterion for obtaining an ontology of better
quality (having the minimum of semantic/logical conflicts). We have also
proposed new terminology and definitions that clarify the unclear and misplaced
"integration" and "merging" notions that are randomly used in state-of-the-art
works. Finally, we tested and evaluated our OIA2R tool using ontologies and
reference alignments of the OAEI campaign. It turned out that it is generic,
efficient and powerful enough.
