Ontology alignment is an important task for information integration. Current ontology matchers are not efficient for all application domains or ontologies. Very often the quality of the results can be improved by considering the specificities of the ontologies domain. In this paper, we propose an environment, called TaxoMap Framework, based on TaxoMap, an alignment tool, which helps an expert to specify treatments based on alignment results. The aim is to refine these results or to merge, restructure or enrich ontologies. We apply our approach to mapping refinement in the topographic field within the ANR project, GéOnto.
