Rule-Based Generation of Diff Evolution Mappings Between Ontology Versions
Ontologies such as taxonomies, product catalogs or web directories are heavily used and hence evolve frequently to meet new requirements or to better reflect the current instance data of a domain. To effectively manage the evolution of ontologies it is essential to identify the difference (Diff) between two ontology versions. The authors propose a novel approach to determine an expressive and invertible diff evolution mapping between given versions of ontology. Their approach utilizes the result of a match operation to determine an evolution mapping consisting of a set of basic change operations (insert/ update/delete).
