= Definition: ContextOntology = A ContextOntology defines a subontology, centering on single class of another ontology, called the '''anchor'''. The set a classes belonging to this new ontology is defined by adding all related classes within a certain distance to it. The relation currently used for this step is the subclass relation, but any other class-to-class relation could be used just as well. The distance is to be called '''context depth'''. The resulting set of classes is then interpreted as a new (sub)ontology. Every relation/property of the original classes could be used, but has to be truncated to the classes that are actually contained in the new ontology.
