The Geospatial Web will have a profound impact on managing knowledge, structuring workflows within and across organizations, and communicating with like-minded individuals in virtual communities. The enabling technologies for the Geospatial Web are geo-browsers such as NASA World Wind, Google Earth and Microsoft Live Local 3D. These three-dimensional platforms revolutionize the production and consumption of media products. They not only reveal the geographic distribution of Web resources and services, but also bring together people of similar interests, browsing behavior, or geographic location.

This book summarizes the latest research on the Geospatial Weba (TM)s technical foundations, describes information services and collaborative tools built on top of geo-browsers, and investigates the environmental, social and economic impacts of geospatial applications. The role of contextual knowledge in shaping the emerging network society deserves particular attention. By integrating geospatial and semantic technology, such contextual knowledge can be extracted automatically a" for example, when processing Web documents to identify relevant content for customized news services.

Presenting 25 chapters from renowned international experts, this edited volume will be invaluable to scientists, students, practitioners, and all those interested in the emerging field of geospatial Web technology. Updates and additional resources are available at www.geospatialweb.com.

Foreword by Patrick J. Hogan, Program Manager of NASA World Wind.

The book at hand re?ects on the increasing convergence of Social Media and Semantic Web technologies. It was the editors' intention to collect - to-date and high quality contributions that illustrate various approaches to this young and emerging technology area. To guarantee this we invited be- of authors from the international conferences I-SEMANTICS and I-KNOW from the years 2007 & 2008 that took place in Graz / Austria to prepare - tended contributions that illustrate this agile and fast-evolving development and hint at trends that might accompany us for the years to come. More than 60 authors from 12 countries with either academic or industrial ba- ground provided us with 20 articles covering a broad range of topics related to frameworks, applications and concrete use cases. After more than a year of preparation we would like to thank all authors for sharing their experiences and insights with the reader. We also would like to thank them for their motivation, dedication and creativity uncompla- inglyincludingourfeedbackintotheircontributionstherebyensuringthehigh qualityofthebook.

This volume emphasizes the applications and implications of the Geospatial Web and the role of contextual knowledge in shaping the emerging network society. There is a clear focus on applied geospatial aspects. The book has contributions from a very active research community. Containing chapters from renowned researchers and practitioners, this volume will be invaluable to all interested in this field.

This book constitutes the refereed proceedings of the First European Conference on Technology Enhanced Learning, EC-TEL 2006. The book presents 32 revised full papers, 13 revised short papers and 31 poster papers together with 2 keynote talks. Topics addressed include collaborative learning, personalized learning, multimedia content, semantic web, metadata and learning, workplace learning, learning repositories and infrastructures for learning, as well as experience reports, assessment, and case studies, and more.

Anwendungen und Technologien des Web 2.0 finden immer mehr in die Unternehmenswelten Einzug, um dort Mitarbeiter verstarkt zum Wissenstransfer zu bewegen eine Entwicklung, die mit dem Begriff Enterprise 2.0 bezeichnet wird. Alexander Stocker und Klaus Tochtermann stellen in elf umfangreichen Fallstudien dar, wie Wikis und Weblogs erfolgreich im Unternehmen eingesetzt werden konnen. Mit ihrem Buch wollen sie vor allem auch Entscheidungstrager aus der Wirtschaft dabei unterstutzen, Nutzen und Erfolg von Web 2.0 im Kontext von Unternehmen besser zu erkennen. Das Buch vermittelt das notwendige Grundverstandnis, um eigene Projekte im Umfeld von Web 2.0 effizienter und effektiver durchzufuhren. Fur die 2. Auflage wurde das Buch korrigiert und um neue Entwicklungen erganzt."

ExpertMedia is growing in popularity and brings together the well-established disciplines of Human-Computer Interaction and Artificial Intelligence."ExpertMedia" is a neologism from expert systems and hypermedia systems and is intended to synergistically combine the advantages of each of these components:Expert System + HyperMedia System = ExpertMediaKey practitioners in the field have been meeting at the past two World Congresses on Expert Systems (1991 in Orlando and 1994 in Lisbon). Their experience in the field is brought together in this book which disseminates information about this innovative area to a large audience. The book consists of three different parts: The first part introduces ExpertMedia in general, the second part focuses on case studies of ExpertMedia and Medical Applications, and the last part deals with ExpertMedia and Knowledge-based Systems.
