Model-Driven Architecture (MDA) is an initiative proposed by the Object Management Group (OMG) for platform-independent software development. It promotes the use of models in the specification, design, analysis, synthesis, deployment, and evolution of complex software systems. ECMDA-FA is dedicated to advancing the state of knowledge and fostering the industrialisation of the MDA methodology. Its focus is on engaging key figures of research and industry, in Europe and elsewhere, in a dialogue which will result in a stronger, more efficient industry, producing more reliable software on the basis of state-of-the-art research results. The 2009 conference is organised in two tracks dealing with the foundations and applications of MDA. There will be additional workshops and tools and poster exhibitions on these subjects. ECMDA-FA 2009 will be held at the University of Twente, in Enschede, the Netherlands.

The vision of the Semantic Web is to enhance today's Web by exploiting machine-processable metadata. The explicit representation of the semantics of data, enriched with domain theories (ontologies), will enable a web that provides a qualitatively new level of service. It will weave together a large network of human knowledge and makes this knowledge machine-processable. Various automated services will help the users to achieve their goals by accessing and processing information in machine-understandable form. This network of knowledge systems will ultimately lead to truly intelligent systems, which will be employed for various complex decision-making tasks. Semantic Web research can benefit from ideas and cross-fertilization with many other areas: Artificial Intelligence, Natural Language Processing, Databases and Information Systems, Information Retrieval, Multimedia, Distributed Systems, Social Networks and Web Engineering. Many advances within these areas can contribute towards the realization of the Semantic Web.

The 6th Annual European Semantic Web Conference (ESWC2009) will present the latest results in research and applications of Semantic Web technologies. ESWC2009 will also feature a tutorial program, system descriptions and demos, a posters track, a PhD Symposium and a number of collocated workshops.

The aim of STI International Offsite is to strenghten the networking amongst the STI members and to support the interaction between the Ph.D. students and researchers of the community.

in conjunction with the 10th International Conference on Mobile Data Management (MDM'09)
Today, computers are changing from big, grey, and noisy things on our desks to small, portable, and ever-networked devices most of us are carrying around. This new form of mobility imposes a shift in how we view computers and the way we work with them.
Services offer the possibility to overcome the limitations of individual mobile devices by making functionality offered by others available to them on an “as-needed” basis. Thus, using the service-oriented computing paradigm in mobile environments will considerably enlarge the variety of accessible applications and will enable new business opportunities in the mobile space by delivering integrated functionalities across wireless networks. Network hosted mobile services will allow mobile operators and third party mobile services provider to extend their businesses by making their network services available to a broader audience (e.g. developers, service providers, etc.); device hosted service will allow great potential for big innovations for applications and services that can be provided by individual mobile device owners.

Knowledge-based technologies use machine-understandable formalizations of expert knowledge to realize scalable, robust and economically feasible approaches and to support knowledge management, information integration or intelligent search. In order to encourage the wide industrial uptake of knowledge-based technologies, instruments to assess potential economic benefits of these technologies and to predict the total costs of their development and deployment are a must.

This workshop addresses economic aspects of knowledge-based technologies. This includes the assessment of their potential business value, more precisely the costs and benefits of their application, and qualitative and quantitative methods therefor. We are interested in original research looking into the aforementioned aspects for both knowledge-based systems and knowledge structures (i.e., ontologies, taxonomies, folksonomies) supporting these systems.

The goal of the workshop is to provide a communication platform for researchers to discuss ideas and results and to identify new challenges in the areas of economics and knowledge-based technologies. The workshop is also intended to be a networking event for participants from the industry willing to share their experiences on the adoption of knowledge-based technologies in enterprises.

The Web 2.0 movement has brought a new generation of usability and socio-technical change to the Web. At the same time, several so-called Web 2.0 applications had enormous success: Wikipedia, del.icio.us, Flickr, YouTube, Facebook, Twitter, Geni – to name just a few. Having differing objectives, they all have something in common: huge amounts of enthusiastic users contributing and creating a plethora of content. The high acceptance of these applications with Web users from all over the world prove that they are usable and – more importantly – provide some kind of benefit. Each of the applications has incentive structure well in place, triggering user interest and involvement.

The aim of the workshop is to address the following questions around incentives and motivation of Web applications: what is the motivation for a user to (install and) use a tool? Which incentive structures can be applied to the Web, which cannot? Moreover, incentives are a crucial topic for future Web generations: Web paradigms, like the Semantic Web or the 3D Web, that are novel and unfamiliar to end users, aim to involve wide user bases. WEBCENTIVES will attract contributions analyzing, applying, and designing incentive structures for Web applications. We want to emphasize that the workshop also aims at failures, i.e. cases where incentives failed, in order to understand why they failed and to disseminate the lessons learned.

Computer Science in the 20th century was about perfect solutions in closed domains and applications. Computer Science in the 21st century will be about approximate solutions and means to capture the relationships between partial solutions and user requirements in terms of computational costs, ensuring a proper balance of their ratio, applicable in environments such as the Internet of the tomorrow. Semantics will provide the theoretical and technological framework for properly addressing this challenge.
The primary aim of the ÖCG Forum Semantic Systems 2008 is to bring together researchers, industry practitioners and decision makers to analyze the current state of play in the area of semantics and discuss its role in the global context of the ICT developments of the last years. A second aim of the event is to identify the instruments necessary to maximize the impact that semantic technologies can potentially have in the realization of the future Internet and to position Austrian R&D in this market at the European and international level.
The forum will be organized as a full-day event consisting of several sessions: invited talks by national and international key players, panel discussions, poster presentations and demonstrations, workshops.  It will be held in the seminar facilities of ÖCG in Vienna.

The Semantic Web Service Retreat will be an intensive 5 day course, training existing and new researchers and practitioners in the field of Semantic Web Services. Please visit the website for further information, e.g. the preliminary program, and instructions on how to apply for participation.
