Networked Knowledge - Networked Media

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.
