Abstract

Die große Fülle an nutzergeneriertem Content im Web 2.0 bedarf einer Strukturierung, will man diese Inhalte sinnvoll nutzen können. Im Internet hat sich mit den Folksonomies eigenständig eine Methode zur inhaltlichen Erschließung von digitalen Ressourcen etabliert. Die Verschlagwortung durch freie, von den Nutzern erstellte Tags zeigt viel Potential, birgt aber auch einige Risiken. Der Beitrag soll grundlegend in die Funktionsweise von Folksonomies einführen und dabei auch Vor- und Nachteile dieser Methode der Wissensrepräsentation ansprechen. Außerdem soll anhand von Beispielen kurz gezeigt werden, wie Folksonomies sinnvoll von Bibliotheken eingesetzt werden können.

Abstract

There are close to a billion websites on the Internet with approximately 400 million users worldwide [www.internetworldstats.com]. People go to websites for a wide variety of different information tasks, from finding a restaurant to serious research. Many of the difficulties with searching the Web, as it is structured currently, can be attributed to increases to scale. The content of the Web is now so large that we only have a rough estimate of the number of sites and the range of information is extremely diverse, from blogs and photos to research articles and news videos.

Abstract

This article examines tagging as knowledge organization. Tagging is a kind of indexing, a process of labelling and categorizing information made to support resource discovery for users. Social tagging generally means the practice whereby internet users generate keywords to describe, categorise or comment on digital content. The value of tagging comes when social tags within a collection are aggregated and shared through a folksonomy. This article examines definitions of tagging and folksonomy, and discusses the functions, advantages and disadvantages of tagging systems in relation to knowledge organization before discussing studies that have compared tagging and conventional library-based knowledge organization systems. Approaches to disciplining tagging practice are examined and tagger motivation discussed. Finally, the article outlines current research fronts.
