- Abstract
- Recently, a growing amount of systems that allow personal content annotation (tagging) are being created, ranging from personal sites for organising bookmarks (del.icio.us), photos (flickr.com) or videos (video.google.com, youtube.com) to systems for managing bibliographies for scientific research projects (citeulike.org, connotea.org). Simultaneously, a debate on the pro and cons of allowing users to add personal keywords to digital content has arisen. One recurrent point-of-discussion is whether tagging can solve the well-known vocabulary problem: In order to support successful retrieval in complex environments, it is necessary to index an object with a variety of aliases (cf. Furnas 1987). In this spirit, social tagging enhances the pool of rigid, traditional keywording by adding user-created retrieval vocabularies. Furthermore, tagging goes beyond simple personal content-based keywords by providing meta-keywords like funny or interesting that "identify qualities or characteristics" (Golder and Huberman 2006, Kipp and Campbell 2006, Kipp 2007, Feinberg 2006, Kroski 2005). Contrarily, tagging systems are claimed to lead to semantic difficulties that may hinder the precision and recall of tagging systems (e.g. the polysemy problem, cf. Marlow 2006, Lakoff 2005, Golder and Huberman 2006). Empirical research on social tagging is still rare and mostly from a computer linguistics or librarian point-of-view (Voß 2007) which focus either on the automatic statistical analyses of large data sets, or intellectually inspect single cases of tag usage: Some scientists studied the evolution of tag vocabularies and tag distribution in specific systems (Golder and Huberman 2006, Hammond 2005). Others concentrate on tagging behaviour and tagger characteristics in collaborative systems. (Hammond 2005, Kipp and Campbell 2007, Feinberg 2006, Sen 2006). However, little research has been conducted on the functional and linguistic characteristics of tags.1 An analysis of these patterns could show differences between user wording and conventional keywording. In order to provide a reasonable basis for comparison, a classification system for existing tags is needed.

- Abstract
- Dieser Artikel beschäftigt sich mit den Möglichkeiten der Informationsaufbereitung durch computergenerierte dreidimensionale Elemente. Visualisierungen durch 3DGrafiken und Animationen können im Vergleich zum Informationsgehalt andersartiger Darstellungen einen kommunikativen Mehrwert aufweisen, der den höheren Aufwand der Erzeugung rechtfertigt. Es wird die Frage aufgeworfen, in welchen Forschungsgebieten der Informationswissenschaft und Medieninformatik der Einsatz von räumlichen Repräsentationen angebracht ist und inwieweit sich die Fokussierung auf eine Informationsübermittlung durch eine virtuelle 3D-Umgebung mit den gesteigerten Anforderungen an das Kommunikationssystem in Einklang bringen lässt. Durch die menschliche Ausrichtung auf möglichst natürliche und realistische Erscheinungen bei der Informationsaufnahme ist die Verwendung der dritten Dimension im Kommunikationsprozess ausgenommen hilfreich, es bedarf zuvor allerdings einer Konzeption geeigneter Einsatzprinzipien, die der großflächigen Anwendung im Bedarfsfall gerecht werden.
