[IxDA Discuss] Taxonomy Folksonomy ?

[Sascha A.Carlin]

Julie,

there are two approaches to generate clusters and hierarchies from
folksonomies I know of.

[Heymann2006]
Heymann, Paul & Garcia-Molina, Hector: Collaborative Creation of
Communal Hierarchical Taxonomies in Social Tagging Systems.

Begelman, Keller and Smadja try to create tag clusters based on the
frequency of occurrence of tags in the same tag group (a tag group is
the entirety of tags used by one user to describe one resource).

Heymann and Garcia-Molina describe a system that generates a
hierarchy based on more or less the same similarity Begelman, Keller
and Smadja use. But instead of creating clusters, they compute the
similarity and use this value to either order a tag under another one
take this tag and treat it as a new heading.

Sascha
