We're excited to announce the technical program of OWLED 2012! Notice that the program is packed so some coffee breaks may be 5-10 mins shorter than usual. We hope that 20-25 mins breaks are still OK but you'll also get a chance to hear about more OWL stuff than usual!

Sunday, May 27th

9:00-9:15: Welcome introduction (Matthew Horridge and Pavel Klinov)

9:15-10:15: Invited talk (Markus Krötzsch): Small OWLs at Large! But Where are They Going?

Lightweight ontology languages have gained significant practical importance in recent years. The standardisation of the OWL 2 Profiles EL, RL, and QL has inspired the development of a variety of new reasoners. Formerly problematic ontologies can now be classified within seconds, and RDF databases support OWL reasoning with "Web-scale" data. As the feature coverage of lightweight reasoners improves, practitioners can take advantage of more and more OWL even on large scales. However, in spite of these advances, OWL is far from being the solution to all knowledge modelling problems. Choosing between the various OWL profiles, semantics, and tools is not always easy, and many applications require expressivity that is still beyond OWL as a whole. For example, Wikidata -- the upcoming database version of Wikipedia -- already encounters the limits of OWL when trying to encode simple factual knowledge. Meanwhile, new developments in SPARQL, RDF, and even XML Schema call for updates of OWL tools, and some even see a need for OWL 3. This talk gives an overview of the OWL Profiles, presents some recent developments in lightweight OWL reasoning, and discusses the emerging challenges for tool developers and for the OWL language as a whole.

14:00-15:30: Tutorial: Introduction to Modularity for OWL Ontologies by Chiara Del Vescovo and Dmitry Tsarkov
This tutorial aims to give a taste of module-based ontology management. First, we introduce the concept of module along with various essential properties of modules. Then, we explore modularity in the context of ontology reuse. Moreover, we guide the participants through the use of tools to support modular ontology development. Finally, we briefly discuss other applications of modularity to ontology engineering.

This tutorial provides a comprehensive overview of research on evolution of (OWL and RDF) ontologies. We give a high-level review of the field, and put special emphasis on (i) practically interesting issues, applications and system demos and (ii) particularly important research results, algorithms, and challenges. This tutorial does not have any specific prerequisites and should be accessible to all Semantic Web researchers and practitioners.
