The problem becomes more severe with the increasing fraction of multimedia data, from which it is difficult to extract some conceptual description of their contents. 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.http://www.bibsonomy.org/bibtex/25854a71547051543dd3d3d5e2e2f2b67/nepomuknepomuk2007-03-22T18:29:28+01:002006 bibsonomy bookmarking folksonomy from:pchirita iccs l3s myown nepomuk social wp5 <span class="authorEditorList"><a href="/author/Hotho">Andreas Hotho</a>, <a href="/author/Jäschke">Robert Jäschke</a>, <a href="/author/Schmitz">Christoph Schmitz</a>, and <a href="/author/Stumme">Gerd Stumme</a> </span><em>Proceedings of the First Conceptual Structures Tool Interoperability Workshop at the 14th International Conference on Conceptual Structures, </em><em>page 87-102. </em><em>Aalborg, </em><em>Aalborg Universitetsforlag, </em>(<em>2006</em>)Thu Mar 22 18:29:28 CET 2007AalborgProceedings of the First Conceptual Structures Tool Interoperability Workshop at the 14th International Conference on Conceptual Structures87-102{BibSonomy}: A Social Bookmark and Publication Sharing System20062006 bibsonomy bookmarking folksonomy from:pchirita iccs l3s myown nepomuk social wp5 Social bookmark tools are rapidly emerging on the Web.

Wir geben in diesem Kapitel einen Überblick über zwei aktuelle Ansätze, die durch kollaboratives Wissensmanagement diese Probleme lösen können. Im Peer-to-Peer-Wissensmanagement unterhalten Benutzer dezentrale Wissensbasen, die dann vernetzt werden können, um andere Benutzer eigene Inhalte nutzen zu lassen. Folksonomies versprechen, die Wissensakquisition so einfach wie möglich zu gestalten und so viele Benutzer in den Aufbau und die Pflege einer gemeinsamen Wissensbasis einzubeziehen.http://www.bibsonomy.org/bibtex/22f59e26c7ab10b526b0e78f50c1e28a9/nepomuknepomuk2007-03-22T18:29:28+01:00databases from:pchirita l3s nepomuk query schemas wp2 <span class="authorEditorList"><a href="/author/Zhou">Xuan Zhou</a>, <a href="/author/Gaugaz">Julien Gaugaz</a>, <a href="/author/Balke">Wolf-Tilo Balke</a>, and <a href="/author/Nejdl">Wolfgang Nejdl</a> </span><em>Proc. of the SIGMOD Conference, </em>(<em>2007</em>)Thu Mar 22 18:29:28 CET 2007Proc. of the SIGMOD ConferenceQuery Relaxation Using Malleable Schemas2007databases from:pchirita l3s nepomuk query schemas wp2 http://www.bibsonomy.org/bibtex/251846aa7d79dcefef1c3335de3c0629f/nepomuknepomuk2007-03-22T18:29:28+01:00dataset desktop from:pchirita l3s nepomuk wp2 <span class="authorEditorList"><a href="/author/Chernov">Sergey Chernov</a>, <a href="/author/Serdyukov">Pavel Serdyukov</a>, <a href="/author/Chirita">Paul-Alexandru Chirita</a>, <a href="/author/Demartini">Gianluca Demartini</a>, and <a href="/author/Nejdl">Wolfgang Nejdl</a> </span><em>In Proceedings of the 29th European Conference on Information Retrieval ECIR, </em>(<em>2007</em>)Thu Mar 22 18:29:28 CET 2007In Proceedings of the 29th European Conference on Information Retrieval (ECIR)Building a Desktop Search Test-bed2007dataset desktop from:pchirita l3s nepomuk wp2 http://www.bibsonomy.org/bibtex/2e382b38623a44151844e656e2d42140d/nepomuknepomuk2007-03-22T18:29:28+01:00dblp from:pchirita l3s nepomuk wp2 <span class="authorEditorList"><a href="/author/Chirita">Paul-Alexandru Chirita</a>, and <a href="/author/Nejdl">Wolfgang Nejdl</a> </span><em>SPIRE, </em><em>volume 4209 of Lecture Notes in Computer Science, </em><em>page 86-97. </em><em>Springer, </em>(<em>2006</em>)Thu Mar 22 18:29:28 CET 2007SPIREconf/spire/200686-97Lecture Notes in Computer ScienceAnalyzing User Behavior to Rank Desktop Items.42092006dblp from:pchirita l3s nepomuk wp2 dblphttp://www.bibsonomy.org/bibtex/24d8b4f79814691fbe6db8357d63206a1/nepomuknepomuk2007-03-22T18:29:28+01:002006 algorithm folkrank from:pchirita ir l3s myown nepomuk pagerank ranking wp5 <span class="authorEditorList"><a href="/author/Hotho">Andreas Hotho</a>, <a href="/author/Jäschke">Robert Jäschke</a>, <a href="/author/Schmitz">Christoph Schmitz</a>, and <a href="/author/Stumme">Gerd Stumme</a> </span><em>Proc.

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.
