Knowledge Evolution Supporting Automatic Workflow Composition

Benefits of using ontologies for automatic composition of workflow application, become evident when considering knowledge evolution influencing possibility of new workflows composition. The evolution of knowledge in the case of ontology descriptionmeans both evolution of the instance registries as well as evolution of schemas to which the instance descriptions conform. An approach to semi-automated knowledge evolution referred to ontology schemas applied to the process of new Grid service registration is introduced in the paper. The presented study makes extensive use of ontology alignment methods.
