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!
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.

11:00-12:30: Tutorial: Evolution of OWL 2 QL and EL Ontologies by Bernardo Cuenca Grau, Ernesto Jimenez-Ruiz, Evgeny Kharlamov and Dmitriy Zheleznyakov
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.
