A survey of tag cloud
presentation techniques
Mogens Nielsen
June 6th 2007
Introduction
•
About tag clouds
–
What and why?
•
Current presentation techniques
•
New presentation techniques
•
Proof of concept
Intention
•
Show current presentation techniques
•
Show new presentation techniques
•
Discuss different presentation techniques
•
Show suggestions to second generation tag
clouds
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
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”)
Current presentation techniques
•
First generation tag cloud (from Flickr)
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
New presentation techniques
•
Clustering tags in the tag cloud
•
Time management
•
Interactivity
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
Clustered tag clouds
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
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
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
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
