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.
