Abstract. In open or evolving systems, different parties could adopt different ontologies. This fact, instead of reducing the semantic hetero- geneity, moves the heterogeneity problems to a higher level. A plausible solution to this problem is the ontology-matching process, which aims at finding correspondences between semantically related entities of different ontologies. In this paper, an approach for improving this set of correspon- dences, called alignment, is proposed. This approach is based on the idea of making explicit features generally implicit in the ontologies.In open or evolving systems, different parties could adopt different ontologies.
