How to Summarize an OWL Domain Ontology

With the Semantic Web Initiative, the Internet more and more becomes an Internet which contains ontologies for different domains. Such ontologies were mainly generated to be machine interpretable. Nevertheless, in a digital Society also the human reader must have the possibility to decide if an ontology is usable for his purpose. This paper will present an approach which allows getting a quick overview of the focus of an ontology. In order to fulfill this, the paper describes how to generate a controlled natural language summary of the ontology for the human reader.
