The most important attribute of geospatial platforms is their unique potential to aggregate a multitude of public and private geographic data sets, providing access to data from government agencies, industry and the general public. NASA and other organizations have a wealth of planetary science data – representing the output from thousands of satellites in earth-orbit, and from dozens of costly missions to other planets. Benefits derived from both the data and visual interfaces to access the data represent a significant return on investment for the public. Integrating geospatial data with semantic and collaborative Web technology multiplies the public benefits and represents the main focus of this book. The user interfaces of geobrowsers are designed for the layperson, giving conv- ient access to all kinds of geographically referenced information. Geobrowsers hide the technical details related to finding, accessing and retrieving such information. The daunting challenge of the Geospatial Web is to seamlessly integrate and display vastly different information modes. Nowadays, it is not enough to simply display a map of some region; additional dynamic information modes need to be displayed and put into context – from weather sensor readings and live aerial video feeds to daily news updates, photo collections and video archives.

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.

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.SpecialthanksalsogotoGiselaGranitzerfromtheKnow Center in Graz who accompanied the editorial process with valuable c- ments and contributionsand helped us to ?nally bringing this volume to you.

Anwendungen und Technologien des Web 2.0 finden immer mehr in die Unternehmenswelten Einzug, um dort Mitarbeiter verstärkt 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 können. Mit ihrem Buch wollen sie vor allem auch Entscheidungsträger aus der Wirtschaft dabei unterstützen, Nutzen und Erfolg von Web 2.0 im Kontext von Unternehmen besser zu erkennen. Das Buch vermittelt das notwendige Grundverständnis, um eigene Projekte im Umfeld von Web 2.0 effizienter und effektiver durchzuführen. Für die 2. Auflage wurde das Buch korrigiert und um neue Entwicklungen ergänzt.

Aufgrund der neuen Nutzungsmöglichkeiten im World Wide Web, bzw. dem neuen Web 2. 0, haben sich Menschen von ehemals passiven Informationskonsumenten zu nunmehr sehr aktiven Informationsproduzenten verwandelt. Neue Anwendungen und Technologien gelten dabei als Auslöser dieser Evolution. Die Möglichkeit, selbst Informationen zu generieren und anderen verfügbar zu machen, übt eine unglaubliche Faszination aus. Die Zuwachsraten von Online-Informationsangeboten, etwa in Weblogs und Wikis, unterstreichen dies. Auch Unternehmen erkennen die Potentiale, die in den neuen Möglichkeiten des Web stecken. Dort, wo im Web schon heute „user generated content“ eine Vorreiterrolle einnimmt, gewinnt in Unternehmen analog „employee generated content“ verstärkt an Bedeutung. Längst ist auch klar geworden, dass das Web 2. 0 dazu beitragen wird, die Art und Weise, wie Wissensarbeit in Unternehmen passiert, nachhaltig zu revolutionieren. In diesem Kontext haben sich sowohl in der Wissenschaft als auch in der Unternehmenspraxis bereits Begriffe wie „Corporate Web 2. 0“ oder „Enterprise 2. 0“ etabliert. Dieses Buch leistet einen wesentlichen Beitrag, um diese Begriffe einzuführen und die damit verbundenen Möglichkeiten aufzuzeigen. Es wendet sich sowohl an Forschende, die sich mit dem Thema Web 2. 0 aus wissenschaftlicher Sicht befassen, als auch an Praktiker, die vor der Frage stehen, wie sie Instrumente des Web 2. 0 in ihr Unternehmen einführen. Die Entstehung dieses Buchs lässt sich aus der Tatsache ableiten, dass Unternehmen aktuelle Trends wie „Web 2. 0“ und „Enterprise 2.
