Editing Large OWL Ontologies

Over the last few years, ontologies became a cornerstone of many areas of computer science, the most prominent example being the semantic web. Ontologies will usually be developed by people who are not experts in knowledge representation. Moreover, in many use cases, the ontologies will be very large. Thus, it is essential to provide easyto-understand browsing and editing tools for very large ontologies. After discussing those requirements, we present ALOE, a graphical editor for large OWL ontologies which is built on top of an existing ontology man-
