- Abstract
- This article investigates the dynamic features of social tagging vocabularies in Delicious, Flickr, and YouTube from 2003 to 2008. Three algorithms are designed to study the macro- and micro-tag growth as well as the dynamics of taggers' activities, respectively. Moreover, we propose a Tagger Tag Resource Latent Dirichlet Allocation (TTR-LDA) model to explore the evolution of topics emerging from those social vocabularies. Our results show that (a) at the macro level, tag growth in all the three tagging systems obeys power law distribution with exponents lower than 1; at the micro level, the tag growth of popular resources in all three tagging systems follows a similar power law distribution; (b) the exponents of tag growth vary in different evolving stages of resources; (c) the growth of number of taggers associated with different popular resources presents a feature of convergence over time; (d) the active level of taggers has a positive correlation with the macro-tag growth of different tagging systems; and (e) some topics evolve into several subtopics over time while others experience relatively stable stages in which their contents do not change much, and certain groups of taggers continue their interests in them.

- Abstract
- Teile und sammle könnte der moderne Leitspruch für das Phänomen Social Tagging heißen. Die freie und kollaborative Verschlagwortung digitaler Ressourcen im Internet gehört zu den Anwendungen aus dem Kontext von Web 2.0, die sich zunehmender Beliebtheit erfreuen. Der 2003 gegründete Social Bookmarking Dienst Del.icio.us und die 2004 entstandene Bildersammlung Flickr waren erste Anwendungen, die Social Tagging anboten und noch immer einen Großteil der Nutzer/innen an sich binden. Beim Blick in die Literatur wird schnell deutlich, dass Social Tagging polarisiert: Von Befürwortern wird es als eine Form der innovativen Wissensorganisation gefeiert, während Skeptiker die Dienste des Web 2.0 inklusive Social Tagging als globale kulturelle Bedrohung verdammen. Launischer Hype oder Quantensprung was ist dran am Social Tagging? Mit der Zielsetzung, mehr über die Erwartungen, Anwendungsbereiche und Nutzungsweisen zu erfahren, wurde im Frühjahr 2008 am Institut für Wissensmedien (IWM) in Tübingen ein Workshop der Gesellschaft für Medien in der Wissenschaft (GMW) durchgeführt. Die vorliegende Publikation fasst die Ergebnisse der interdisziplinären Veranstaltung zusammen.
