This paper presents an approach for ontology translation in the O3F ontology framework and a concrete implemented agent that translates between ontologies expressed in OWL. In the O3F framework, ontology translation is a recursive process based on a mapping from the basic concepts of the object ontology to concepts of the target ontology. Using available mappings, it is possible to recursively translate compound concepts. The paper also presents a scenario where two agents using different ontologies interact with the ontology translation agent in order to communicate.
