Tags are used for navigation, finding resources and serendipitous browsing and thus provide an immediate benefit for users. These systems usually include tag recommendation mechanisms easing the process of finding good tags for a resource, but also consolidating the tag vocabulary across users. In practice, however, only very basic recommendation strategies are applied.

In this paper we evaluate and compare two recommendation algorithms on largescale real life datasets: an adaptation of user-based collaborative filtering and a graph-based recommender built on top of FolkRank. We show that both provide better results than non-personalized baseline methods. Especially the graph-based recommender outperforms existing methods considerably.

lightweight conceptual structures called folksonomies. Currently,

the information retrieval support is limited. We present a formal

model and a new search algorithm for folksonomies, called

FolkRank, that exploits the structure of the folksonomy. The

proposed algorithm is also applied to find communities within the

folksonomy and is used to structure search results. All findings are

demonstrated on a large scale dataset. A long version of this paper

has been published at the European Semantic Web Conference

2006.
