As more and morepeople participate in the effort, the use of a common vocabularybecomes more and more stable. We present an approach for discoveringtopic-specific trends within folksonomies. It is based on adifferential adaptation of the PageRank algorithm to the triadichypergraph structure of a folksonomy.

documents one can track, it becomes increasingly difficult to remain

up to date on ones own areas of interest. The problem becomes more

severe with the increasing fraction of multimedia data, from which

it is difficult to extract some conceptual description of their

One way to overcome this problem are social bookmark tools, which

are rapidly emerging on the web. In such systems, users are setting

up lightweight conceptual structures called folksonomies, and

overcome thus the knowledge acquisition bottleneck. As more and more

people participate in the effort, the use of a common vocabulary

becomes more and more stable. We present an approach for discovering

topic-specific trends within folksonomies. It is based on a

differential adaptation of the PageRank algorithm to the triadic

hypergraph structure of a folksonomy. The approach allows for any

kind of data, as it does not rely on the internal structure of the

documents. In particular, this allows to consider different data

types in the same analysis step. We run experiments on a large-scale

real-world snapshot of a social bookmarking system. ER -
