    Enterprise wikis: technical challenges and opportunities
    (6th Conference on Professional Knowledge Management – From Knowledge to Action, 2011) Kämpgen, Benedikt; Ell, Basil; Simperl, Elena; Vrandečić, Denny; Dengler, Frank
    Social software has proven valuable in enterprises for collaborative knowledge management. In order to introduce a wiki in the enterprise, we propose a solution that combines Web 2.0 and Semantic Web technologies. We describe how this solution resolves the technical challenges, beyond that, opens up new opportunities, and, also, how it can be realized in a concrete enterprise scenario.

    A Metamodel for Annotations of Ontology Elements in OWL DL
    (Meta-modelling and ontologies – Proceedings of the 2nd Workshop on Meta-Modelling – WoMM 2006, 2006) Vrandečić, Denny; Völker, Johanna; Haase, Peter; Tran Duc, Thanh; Cimiano, Philipp
    OWL DL puts several constraints on the possibilities to talk about the el- ements of an ontology. In particular, it is not possible to make statements about the axioms of an ontology or to make higher-order statements about the classes and prop- erties of an ontology. This lack of expressiveness may cause problems throughout the whole lifecycle of an ontology, and especially in its practical usage. In this paper we discuss different approaches to overcome these problems. We propose a metamodel for OWL DL that allows to express statements about ontology elements, including axioms. We further describe three possible groundings of the metamodel in OWL DL and present a number of tools which we developed to support the user in working with these models. Finally, we describe some use cases for the practical application of our approach.
