Constructing evolutionary taxonomy of collaborative tagging systems
2009
Proceeding of the 18th ACM conference on Information and knowledge management - CIKM '09
Preserved Fulltext
The tags are generally correlated and evolving according to the change of web contents, and the popularity of tags represent evolution of social interests. ...
In this demonstration, we propose to construct the evolutionary taxonomy which incorporates the correlation and evolution of tags, as user generated tags grow and change temporally. ...
The constructed taxonomy can reflect the evolution of user interests and web contents, and facilitate the organization of online resources. CIKM' 09 , 09 November 2-6, 2009, Hong Kong, China. ...

Richer interactions that explicitly allow for a comparative analysis of entities represent a new potential direction to improve the search experience. ...
Another important problem is to explore further techniques to rank and score unreliable comparables without sacrificing the generality of the relation. CIKM'09, November 2-6, 2009, Hong Kong, China. ...
