  1. A survey of tag cloud presentation techniques Mogens Nielsen June 6th 2007

  2. Introduction • About tag clouds • What and why? • Current presentation techniques • New presentation techniques • Proof of concept

  3. Intention • Show current presentation techniques • Show new presentation techniques • Discuss different presentation techniques • Show suggestions to second generation tag clouds

  4. Method • Literature study • Read weblogs to find general interest in tag clouds • Proof of concept to show an example of a second generation tag cloud

  5. Contribution • Tag clouds are a new information visualization interface • Still in the ”prototype” phase • More users and areas of implementation leads to more needs for functionality • Many suggestions to new techniques • This paper will try to gather the available information (create ”order” in the ”chaos”)

  6. Current presentation techniques • First generation tag cloud (from Flickr)

  7. Current presentation techniques • Some limitations of the first generation tag cloud • Alphabetical arrangement does not infer relationships between tags • One or more topics tend to dominate the cloud with their tags • Static; no implementation of time • No interactivity

  8. New presentation techniques • Clustering tags in the tag cloud • Time management • Interactivity

  9. Clustered tag clouds • Shows relations between tags • Limits the synonym problem of tagging (folksonomies) • Less significant tags disappears • Tags with higher meaning emerge and thereby reducing semantic density • The dominating topics are less dominating

  10. Clustered tag clouds

  11. Temporal tag clouds • Ability to discover trends and emerging tags • Shorter popularity decay gives us a less static tag cloud • Cloudalicious: Shows how a webpage is tagged over time • Google Trends: Shows search trends on Google • Flickr: Three stages of tag cloud time frame

  12. Interactive tag clouds • Allow the user to choose the presentation of the tag cloud at her choice • Interactivity gives the user a greater impact on which information the tag cloud should visualize • No interactive tag clouds • Delicious Tagrolls

  13. Proof of concept • PoC to show a vision of abilities in a second generation tag cloud • Implements interactivity which enables the user • To choose time frame • To zoom

  14. Conclusion • Tag clouds are in the starting phase as information visualization interfaces • New implementations and presentation techniques are needed • This paper intends to • Create an order in the chaos • Show a vision of a second generation tag cloud

  15. Demo and questions Thank you for listening
