Where I lost my OWL and how I found it again

Holger Heinz

Ontologies are not static and can change over time. New knowledge is added and existing knowledge is removed. At a later time it can happen that this knowledge must be added back into the ontologie, which can turn out to be expensive if no record of the knowledge has been kept. It is therefore necessary to have tools at hand that support this process. Since Description Logics provide the formal ground for reasoning in ontologies, there is a need for well-defined formal methods that can be used to express these changes.In this talk I give an overview of the current state of my masters's thesis, in which I am concerned with the definition of an operator for the retraction and recovery of information in the context of OWL 2 EL ontologies.
