Ket : People share resources in folksonomies and add tags to these
resources. There are often only a few tags associated with each resource,
which makes the data available in folksonomies extremely sparse. Spareness in folksonomies makes searching resources difficult. Many relevant
resources against a query might not be retrieved if they are not associated
with the queried terms. One possible way to overcome the search problem
in folksonomies is query expansion. We propose and compare different
query expansion techniques for folksonomies and evaluate these methods
on a large scale. We also propose an automated evaluation method for
query expansion. Experimental results show that query expansion helps
in improving search in folksonomies.
