Ontology segmentation or the creation of ontology views is an important issue. Since many ontologies constantly grow in size and are therefore more and more difficult to understand, maintain and edit, ontology segmentation shall help to extract only those parts of a large ontology that are relevant for a certain scenario and to create a stand-alone ontology out of these concepts. Seidenberg and Rector com- pare and evaluate several algorithms for extracting relevant segments in [9]. The key approach is to let the user select some relevant concepts and to automatically add super- classes, subclasses and other related concepts (e.g. classes contained in axioms and restrictions) to the ontology view.
