Abstract

Search in folksonomies is hampered by the fact that the meaning of tags and their relations are not made explicit in the system. This is typically addressed by using knowledge sources (KS) to semantically enrich tagspaces, most nota- bly WordNet and (online) ontologies. However, there is no insight of how the different characteristics of these KS con- tribute to search improvement in folksonomies. In this work we compare these two KS in the context of folkso- nomy search. We show that wh ile WordNet leads to richer tag structures than online ontologies do, its fine-grained sense hierarchy renders these structures less effective in search compared to the ones generated from ontologies.
