Application of an Instance Migration Solution to Industrial Ontologies

Abstract. The paper presents the results of evaluating the software solution for ontology instance migration problem in the use case involving the ontologies used in construction industry – freeClass and eClassOWL with the Bau-DataWeb dataset representing the individuals. Ontology instance migration problem is understood as a sub-problem of ontology alignment. Our methodology assumes (semi-) automated iterative process possibly involving a human for validating the results. The process consists of the two steps: (1) schemabased mappings discovery done by the agent-based matcher software; and (2) ontology instance transformation and migration according to the discovered mappings done by the ontology instance migration engine software. The evaluation experiment has been conducted in two phases and yielded results of acceptable quality in terms of precision, recall, and f-measure
