Ontologies have emerged as a means of facilitating semantic interoperability among computer systems. However, recognizing that no single universally agreed-on ontology can ever be defined for a domain, a tool that allows ontologies to interoperate becomes essential to semantic interoperability. This paper presents an ontology integrator (Onto-Integrator) for facilitating ontology interoperability within the architectural, engineering, and construction (AEC) domain. The Onto-Integrator offers a heuristic for ontology merging, including the merging of concept taxonomies, relations, and axioms. Unlike existing tools, the integrator addresses ontology merging requirements that are specific to the AEC domain. The integrator heuristic was implemented into a prototype Web-based tool and was evaluated through a focus group.
