Abstract
Conflict of ontologies can appear on one of three levels: instance level, concept level and relation level. Conflict on instance level appears when the same instance occurs in different ontologies with different descriptions. Two ontologies are in conflict on concept level if the same concept has different structures in these ontologies. Conflict on relation level refers to different relations between the same two concepts in different ontologies. In this article a method for ontology conflict resolution and integration on relation level is presented. Within this method we present a model for representing ontology conflict and consensus-based algorithms for conflict resolution.
