Abstract

Social tagging, hashtags, and geotags are used across a variety of platforms (Twitter, Facebook, Tumblr, WordPress, Instagram) in different countries and cultures. This book, representing researchers and practitioners across different information professions, explores how social tags can link content across a variety of environments. Most studies of social tagging have tended to focus on applications like library catalogs, blogs, and social bookmarking sites. This book, in setting out a theoretical background and the use of a series of case studies, explores the role of hashtags as a form of linked data?without the complex implementation of RDF and other Semantic Web technologies.

Abstract

Unsere Gesellschaft verändert sich radikal, aber fast unsichtbar. Wir steuern auf einen Totalitarismus zu. Das Private verschwindet, die Macht des Geldes wächst ebenso wie die Ungleichheit, wir kaufen immer mehr und zerstören damit die Grundlage unseres Lebens. Statt die Chance der Freiheit zu nutzen, die historisch hart und bitter erkämpft wurde, werden wir zu Konsum-Zombies, die sich alle Selbstbestimmung durch eine machtbesessene Industrie abnehmen lässt, deren Lieblingswort »smart« ist. Was heißt das für unsere Gesellschaft? Nach seinem Bestseller >Selbst denken< analysiert Harald Welzer in >Die smarte Diktatur. Der Angriff auf unsere Freiheit<, wie die scheinbar unverbundenen Themen von big data über Digitalisierung, Personalisierung, Internet der Dinge, Drohnen bis Klimawandel zusammenhängen. Daraus folgt: Zuschauen ist keine Haltung. Es ist höchste Zeit für Gegenwehr, wenn man die Freiheit erhalten will! Bestseller-Autor Harald Welzer legt mit >Die smarte Diktatur. Der Angriff auf unsere Freiheit< eine neue und frische Analyse der großen gesellschaftlichen Zusammenhänge in Deutschland vor, eine umfassende Diagnose der Gegenwart für alle politisch Interessierten.

Abstract

When "metadata" became breaking news, appearing in stories about surveillance by the National Security Agency, many members of the public encountered this once-obscure term from information science for the first time. Should people be reassured that the NSA was "only" collecting metadata about phone calls -- information about the caller, the recipient, the time, the duration, the location -- and not recordings of the conversations themselves? Or does phone call metadata reveal more than it seems? In this book, Jeffrey Pomerantz offers an accessible and concise introduction to metadata. In the era of ubiquitous computing, metadata has become infrastructural, like the electrical grid or the highway system. We interact with it or generate it every day. It is not, Pomerantz tell us, just "data about data." It is a means by which the complexity of an object is represented in a simpler form. For example, the title, the author, and the cover art are metadata about a book. When metadata does its job well, it fades into the background; everyone (except perhaps the NSA) takes it for granted. Pomerantz explains what metadata is, and why it exists. He distinguishes among different types of metadata -- descriptive, administrative, structural, preservation, and use -- and examines different users and uses of each type. He discusses the technologies that make modern metadata possible, and he speculates about metadata's future. By the end of the book, readers will see metadata everywhere. Because, Pomerantz warns us, it's metadata's world, and we are just living in it.
