Faviki is a social bookmarking tool that lets you use Wikipedia concepts as tags. Faviki allows you to keep your own tags and connect them to common, universal concepts from the world's largest collection of knowledge!
NewsCloud is a site experiment that fetches news from Google News, tries to find tags related to each news and presents a tag cloud of the daily news. During the news process, there's no human intervention.
The aim of the TERM project - Tagging (extra, external) Electronic Resources for Modules - is to investigate the extent to which social bookmarking can be used to promote collaborative learning. The motivation for doing this is to enable students to get more value from the informal collections of on-line resources that they may gather to support their learning. The study has two main strands: identifying the barriers to sharing resources; and exploring potential solutions. The latter has focussed on exploiting both the social and technology opportunities provided by “Web 2.0”
"Collaborative Tagging bietet Bibliotheken die Möglichkeit, ihr Wissensmanagement stärker partizipatorisch auszurichten, in dem es die Kundinnen und Kunden an der Erschließung von Medien beteiligt. Die Universitätsbibliothek Mannheim möchte untersuchen, welchen Beitrag Collaborative Tagging für die inhaltliche Erschließung von bisher nicht erschlossenen und daher der Nutzung kaum zugänglichen Dokumenten leisten kann."
