- Abstract
- Social Tagging ist eine Methode zur semantischen Datenorganisation. Im Unterschied zu traditionellen Ansätzen wird die Kategorisierung nicht von Experten vorgenommen, sondern von einer Vielzahl von Benutzern gemeinschaftlich entwickelt. Bezüglich der Daten existieren grundsätzlich keinerlei Einschränkungen. Dabei kann es sich sowohl um multimediale Inhalte als auch um wissenschaftliche Literatur handeln. Jeder Benutzer, unabhängig von Expertise oder Intention, ist aufgefordert, mithilfe von frei gewählten Tags die Kategorisierung der verwendeten Ressourcen zu unterstützen. Insgesamt entsteht dadurch eine Sammlung verschiedenster subjektiver Einschätzungen, die zusammen eine umfassende semantische Organisation bestimmter Inhalte darstellen. Ziel dieses Buches ist es, zunächst die Grundlagen und Anwendungen von Social Tagging zu erörtern und dann speziell die Effekte im Hinblick auf die Wissensorganisation und die sozialen Beziehungen der Benutzer zu analysieren. Eines der zentralen Ergebnisse dieser Arbeit ist die Erkenntnis, dass die gemeinschaftlich erzeugten Metadaten eine unerwartet hohe Qualität bzw. Bedeutsamkeit aufweisen, obwohl Mehrdeutigkeiten und verschiedene Schreibweisen diese negativ beeinflussen könnten. Social Tagging ist besonders effektiv für die Organisation von sehr großen oder auch heterogenen Daten-beständen, die mit herkömmlichen, experten-basierten Kategorisierungsverfahren nicht mehr verarbeitet werden können oder durch automatische Verfahren qualitativ schlechter indexiert werden. Durch Social Tagging wird nicht nur die Wissensorganisation gefördert, sondern darüber hinaus auch die Zusammenarbeit und der Aufbau von Communities, weshalb Social Tagging auch effizient in der Lehre eingesetzt werden kann.

- Abstract
- Indexing consists of both novel and more traditional techniques. Cutting-edge indexing techniques, such as automatic indexing, ontologies, and topic maps, were developed independently of older techniques such as thesauri, but it is now recognized that these older methods also hold expertise. Indexing describes various traditional and novel indexing techniques, giving information professionals and students of library and information sciences a broad and comprehensible introduction to indexing. This title consists of twelve chapters: an Introduction to subject readings and theasauri; Automatic indexing versus manual indexing; Techniques applied in automatic indexing of text material; Automatic indexing of images; The black art of indexing moving images; Automatic indexing of music; Taxonomies and ontologies; Metadata formats and indexing; Tagging; Topic maps; Indexing the web; and The Semantic Web.

- Abstract
- Multimodalität ist ein typisches Merkmal der Kommunikation im Social Web. Der Fokus dieses Bandes liegt auf der Kommunikation in Foto-Communitys, insbesondere auf den beiden kommunikativen Praktiken des Social Taggings und des Verfassens von Notizen innerhalb von Bildern. Bei den Tags stehen semantische Text-Bild-Relationen im Vordergrund: Tags dienen der Wissensrepräsentation, eine adäquate Versprachlichung der Bilder ist folglich unabdingbar. Notizen-Bild-Relationen sind aus pragmatischer Perspektive von Interesse: Die Informationen eines Kommunikats werden komplementär auf Text und Bild verteilt, was sich in verschiedenen sprachlichen Phänomenen niederschlägt. Ein diachroner Vergleich mit der Postkartenkommunikation sowie ein Exkurs zur Kommunikation mit Emojis runden das Buch ab.

- Abstract
- LIS professionals use structures for organizing knowledge when they catalog and classify objects in the collection, when they develop databases, when they design customized taxonomies, or when they search online. Structures for Organizing Knowledge: Exploring Taxonomies, Ontologies, and Other Schema explores and explains this basic function by looking at three questions: 1) How do we organize objects so that they make sense and are useful? 2) What role do categories, classifications, taxonomies, and other structures play in the process of organizing? 3) What do information professionals need to know about organizing behaviors in order to design useful structures for organizing knowledge? Taking a broad, yet specialized approach that is a first in the field, this book answers those questions by examining three threads: traditional structures for organizing knowledge; personal structures for organizing knowledge; and socially-constructed structures for organizing knowledge. Through these threads, it offers avenues for expanding thinking on classification and classification schemes, taxonomy and ontology development, and structures. Both a history of the development of taxonomies and an analysis of current research, theories, and applications, this volume explores a wide array of topics, including the new digital, social aspect of taxonomy development. Examples of subjects covered include: Formal and informal structures Applications of knowledge structures Classification schemes Early taxonomists and their contributions Social networking, bookmarking, and cataloging sites Cataloging codes Standards and best practices Tags, tagging, and folksonomies Descriptive cataloging Metadata schema standards Thought exercises, references, and a list of helpful websites augment each section. A final chapter, "Thinking Ahead: Are We at a Crossroads?" uses "envisioning exercises" to help LIS professionals look into the future.
