Agenda
• Definitions and background: • Folksonomies• Social navigation • Pivot browsing in Delicious
• Aim for this project• Case: Quilters• Data• Preliminary results• Questions
Definition: Folksonomies
A folksonomy is the collection of user generated subject headings (tags), describing information objects, applied by the end-users.
Background and motivation
• The users’ employment of folksonomies are personal as well as collective
(Golder & Huberman, 2006)
• The use of folksonomies is rising, at the same time there is a lack of empirical studies of the use.
(Jason Morrison, 2008)
• The users navigate folksonomies by browsing other users profiles
(Millen, Feinberg, & Kerr, 2005)
Pivot browsing
Exploratory information seeking behavior• Users click on:
• Other users (profiles)
• Information objects • Tags
Social navigation
• Users’ exploration of information spaces using other users’ actions
• Path in a forrest• Dogears in used books • Recommender systems• Most lent books in the library
(Se: Dieberger, Dourish, Höök, Resnick, & Wexelblat, 2000).
Case study: Delicious.com
A folksonomy where users can save and tag Internet bookmarks, as well as se other users’ bookmarks and tags
(see: Delicious, 2008)

Aim for the PhD project
• Better understanding of the users employment of folksonomies
• Identify use patterns in folksonomies• Develop techniques to support users information behavior in folksonomies
• Investigate to what extent tags can support social navigation
Pilot study
• Case study of a folksonomy• Informetric methods for associating users
• Co-occurrences of tags in user profiles
Case: Quilters
Quilters are charactrized by:• Great passion for their hobby• Use of technologies which can support
them in their hobby• A feeling of being part of a community

Preliminary conclusion
• Tags employed by users in folksonomies can be used as a tool for social navigation.
• This requires investigations of the different types of tags’
