OntologieAlignment
OntologieAlignment, more commonly referred to as ontology alignment or ontology matching, is the process of identifying and establishing correspondences between the entities of different ontologies. The aim is to enable interoperability, data integration, and unified reasoning across heterogeneous knowledge sources. An alignment typically results in a set of mappings between ontology elements such as classes, properties, and individuals, which can be used to translate queries, merge schemas, or drive cross-ontology reasoning.
Entities involved in alignment include classes, properties, and individuals from each ontology. Correspondences may express various
Methods for finding alignments combine lexical, structural, and semantic techniques. Approaches include string similarity for labels,
Evaluation typically uses metrics such as precision, recall, and F-measure, often within standardized benchmarks from the
