Gottlob Georg: Hypergraph Decompositions and their Applications to Constraint Satisfaction and Combinatorial Auctions

One of the best-known methods for decomposing graphs is the method of tree-decompositions introduced by Robertson and Seymour.
Many NP-hard problems become polynomially solvable if restricted to instances whose underlying graph structure has bounded treewidth. However, many problems are better described by hypergraphs than by graphs. In this talk I will report hypergraph decomposition methods, and their application to database query optimization, to constraint satisfaction, and to the winner determination problem in combinatorial auctions. The latter are auctions where each bidder can place bids on sets of items rather than on single items.

About Georg Gottlob

Georg Gottlob is a Professor of Computing Science at Oxford University and an Adjunct Professor at TU Wien. His research interests are database theory Web information processing, graph algorithms, constraint satisfaction problems, logic, and computational complexity. He is a co-founder of the Lixto data extraction company (www.lixto.com). Gottlob got his Engineer and Ph.D. degrees in Computer Science from TU Vienna, Austria in 1979 and 1981, respectively. Before moving to Oxford, he was, since 1988, a Professor of Computer Science at TU Wien.

From 1981 to 1987, he was affiliated with the Italian National Research Council in Genoa, Italy, and with the Politecnico di Milano, Italy. He was a research scholar at Stanford University, in 1999 an invited McKay Professor at UC Berkeley, and in 2002 a Visiting Professor of Univ. Paris VII.

Georg Gottlob was an invited speaker at many international conferences. He received the Wittgenstein Award, a Royal Society Wolfson Research Merit Award, and was elected member of the Austrian Academy of Sciences, of the German Academy of Sciences "Leopoldina", and of the Academia Europaea (London).

Messnarz Richard: European Qualification Network

EQN - European Qualification Network - is an EU Leonardo networking project which
- develops quality rules for job roles / professions offered in the European IT & Services market segment
- establishes a certification association which controls these quality principles and provides a computer supported infrastructure
- configures European self test and exam portal systems to enable same test processes and European based test questions pool for professions

With a modular flexible architecture an EU-wide agreed Skills Set was defined by a European Job Role Committee. Out of a Europe-wide pool of test questions automated by European portals courses (based on the same skills) are held.at universities or are organized by training companies.

He will explain the European Qualification Strategy (www.eu-certificates.org) which contains
- Skills Sets with skills architecture (learning achievements oriented) agreed across EU countries
- European Test Portals
- European Training Portals
- Certificates based on a credit point system per job role (covering skill elements)
- Personal learning strategy based on a EQF promoted level taxonomy

and discuss the opportunities of collaboration and the possibility of certificates (four certificate levels).

About Richard Messnarz

Richard Messnarz is the Executive Director of ISCN. He studied at the University of Technology Graz and he worked as a researcher and lecturer at this University from 1991 - 1996. In 2 European mobility projects (1993 and 1994) he was involved in the foundation of ISCN, and he became the director of ISCN in 1997. He is/has been the technical manager of many European projects:
· TEAMWORK - Strategic E-Working Platform Development and Trial, 2001-2002
· ORGANIC (http://www.innovationmanager.org) - Innovation Management Strategies for Europe (2003 - 2006)
· EQN (European Quality Network) , http://www.eu-certificates.org

He is the general chair of EuroSPI (European Systems and Software Process Improvement and Innovation) Initiative. See EuroSPI 2007 at http://2007.eurospi.net , http://www.eurospi.net He is a principal ISO 15504 lead assessor. He is a founding member of the INTACS (International Assessor Certification Scheme) Board (www.intacs.info). In the CREDIT project he was responsible for the architecture of the systems and later became the project leader of the Capability Adviser system (Skills and ISO 15504 Assessment Portals) development. In the project EPI he was the technical manager responsible for the integratrion of Capability Adviser with a set of LMS (Learning management Systems) in Europe and Eastern Europe.
He is the moderator of industry task forces in Europe in the field of innovation and improvement:
- SOQRATES (www.sowrates.de) task forces (not to confuse with EU program) where 24 leading firms collaborate and exchange innovation knowledge (ZF Friedrichshafen, Siemens, Continental, T-Systems, Panasonic, G&D, etc.)
- S2QI task forces (Siemens, Magna, Flextronics, TU Graz, etc.)

Tjoa Min: Where and why we need semantic modelling in software engineering

A historical perspective of conceptual modelling and there interactions with software engineering concepts to demonstrate the necessity of accurate information modelling for the development of quality software is presented. Based on this analysis which is inherently linked with Parnas’ information hiding principle current and future perspectives in the software engineering domain based on recent semantic modelling approaches will be investigated.

Stumptner Markus: Model-based Software Debugging

A considerable body of work on model-based software debugging (MBSD) has been published in the past decade. We summarise the underlying ideas and present the different approaches as abstractions of the concrete semantics of the programming language. We compare the model-based framework with other well-known Automated Debugging approaches and present open issues, challenges and potential future directions of MBSD.
