Abstract

Semantic annotations assign concepts of a reference ontology to artifacts like documents, web-pages, schemas, or web-services. When an ontology changes, these annotations have probably to be maintained as well. We present an approach for automatically checking whether an annotation is invalidated by a change in the reference ontology. The approach is based on annotation paths and on the explicit definition of change-dependencies between ontology artifacts. Ontology change-logs and change dependencies are then exploited to identify those annotation paths which require maintenance.
