  abstract = {The emergence of collaborative tagging systems with their underlying flat and 
uncontrolled resource organization paradigm has led to a large number of 
research activities focussing on a formal description and analysis of the 
resulting "folksonomies". An interesting outcome is that the characteristic 
qualities of these systems seem to be inverse to more traditional knowledge 
structuring approaches like taxonomies or ontologies: The latter provide rich 
and precise semantics, but suffer - amongst others - from a knowledge 
acquisition bottleneck. An important step towards exploiting the possible 
synergies by bridging the gap between both paradigms is the automatic 
extraction of relations between tags in a folksonomy. This position paper 
presents preliminary results of ongoing work to induce hierarchical 
relationships among tags by analyzing the aggregated data of collaborative 
tagging systems as a basis for an ontology learning procedure.
