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.

Die Herausgeber und Autoren fuhren praxisnah in neue Methoden und Technologien des (Meta-)Daten-Managements fur die Vernetzung und Integration verteilter, heterogener Datenbestande ein. Dabei werden die neuen Technologien und Methoden von bereits etablierten Ansatzen deutlich abgegrenzt, ihre Potenziale und auch ihre Grenzen klar benannt. Vor allem Semantic-Web-Technologien, deren betrieblicher Einsatz anhand anschaulicher Fallstudien erlautert wird, spielen eine zentrale Rolle."

Semantische Techniken zur strukturierten Erschliessung von Web 2.0-Content und kollaborative Anreicherung von Web Content mit maschinenlesbaren Metadaten wachsen zum Social Semantic Web zusammen. Kennzeichnend ist dabei die breite Konvergenz zwischen Social Software und Semantic Web-Technologien. Das Buch stellt die technischen, organisatorischen und kulturellen Veranderungen dar, die das Social Semantic Web begleiten. Entscheidungstrager und Entwickler konnen auf dieser Grundlage die Tragweite dieser Technologie fur ihr Unternehmen erkennen."

This open access book constitutes the refereed proceedings of the 16th International Conference on Semantic Systems, SEMANTiCS 2020, held in Amsterdam, The Netherlands, in September 2020. The conference was held virtually due to the COVID-19 pandemic.

This open access book constitutes the refereed proceedings of the 15th International Conference on Semantic Systems, SEMANTiCS 2019, held in Karlsruhe, Germany, in September 2019. The 20 full papers and 8 short papers presented in this volume were carefully reviewed and selected from 88 submissions. They cover topics such as: web semantics and linked (open) data; machine learning and deep learning techniques; semantic information management and knowledge integration; terminology, thesaurus and ontology management; data mining and knowledge discovery; semantics in blockchain and distributed ledger technologies.

This handbook maps the media economy in its entirety against the background of the advancing digitalization of communication, media production, media distribution and the adaptation of regulatory framework conditions from different disciplinary approaches. It provides an integrated view on digitally induced economic transformations of the European media sector, and gives an explicitly European perspective on media economics – challenging the dominant US-American view. Topics covered include, but are not limited to: Theoretical approaches to media economics; media technologies and data management in media economics; building blocks of the media industry; media types and core distribution markets; system aspects and communication culture; media systems and regulatory policy; as well as methods of media economics. The handbook is a must-read for students, teachers and researchers in media and communication economics and science, as well as practicioners and policy-makers at the nexus of media, business and politics.

Das Handbuch hat den Anspruch, die Medienökonomie vor dem Hintergrund der voranschreitenden Digitalisierung von Kommunikation, Medienproduktion, Medienvertrieb sowie der Anpassung ordnungspolitischer Rahmenbedingungen aus unterschiedlichen disziplinären Zugängen in seiner Gesamtheit abzubilden.
