A global view is usually presented by the tag cloud of the system, but it does not allow a conceptual drill-down, e. g., along a conceptual hierarchy. In this paper, we present a clustering approach for computing such a conceptual hierarchy for a given folksonomy. The hierarchy is complemented with ranked lists of users and resources most related to each cluster. The rankings are computed using our FolkRank algorithm. We have evaluated our approach on large scale data from the del.icio.us bookmarking system.}, biburl = {http://www.bibsonomy.org/bibtex/2334d3ab11400c4a3ea3ed5b1e95c1855/stumme}, keywords = {folksonomy tagorapub social folksonomies sites myown tagging 2007} } @misc{cao07casestudy, title = {Case study on social software use in distributed working environments}, author = {Yiwei Cao and Karsten Ehms and Sebastian Fiedler and Margit Hofer and Anna-Kaarina Kaiamo and Barbara Kieslinger and Ralf Klamma and Beate Krause and Milos Kravcik and Tommi Ryyppö and Marc Spaniol and Gerd Stumme and Fridolin Wild}, note = {Deliverable 15.2, European Network of Excellence ``Prolearn - Professional E-Learning''}, year = 2007, url = {http://www.prolearn-project.org/deliverables/view?id=1432}, biburl = {http://www.bibsonomy.org/bibtex/25dc735281a6be72a54186018e0166740/stumme}, keywords = {software social study 2007 case myown bibsonomy} } @inproceedings{jaeschke07tagKdml, title = {Tag Recommendations in Folksonomies}, author = {Robert Jaeschke and Leandro Marinho and Andreas Hotho and Lars Schmidt-Thieme and Gerd Stumme}, booktitle = {Workshop Proceedings of Lernen - Wissensentdeckung - Adaptivität (LWA 2007)}, editor = {Alexander Hinneburg}, month = {sep}, pages = {13-20}, publisher = {Martin-Luther-Universität Halle-Wittenberg}, year = 2007, url = {http://www.kde.cs.uni-kassel.de/stumme/papers/2007/jaeschke07tagrecommendationsKDML.pdf}, isbn = {978-3-86010-907-6}, biburl = {http://www.bibsonomy.org/bibtex/271bc9f8ae1a53632dc9a2b98b017f152/stumme}, keywords = {folksonomy social filtering collaborative bookmarking myown l3s 2007 recommender} } @inproceedings{jaeschke2007analysis, title = {Analysis of the Publication Sharing Behaviour in {BibSonomy}}, address = {Berlin, Heidelberg}, author = {Robert Jäschke and Andreas Hotho and Christoph Schmitz and Gerd Stumme}, booktitle = {Proceedings of the 15th International Conference on Conceptual Structures (ICCS 2007)}, editor = {U.

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.}, biburl = {http://www.bibsonomy.org/bibtex/2bb8ecec699a2f129322fe334747c6aef/stumme}, keywords = {l3s ranking folksonomies recommendations myown Recommendations Folksonomies nepomuk tagging FolkRank 2007} } @inproceedings{kuznetsov07reducing, title = {Reducing the Representation Complexity of Lattice-Based Taxonomies}, address = {Berlin, Heidelberg}, author = {Sergei Kuznetsov and Sergei Obiedkov and Camille Roth}, booktitle = {Proceedings of the 15th International Conference on Conceptual Structures (ICCS 2007)}, crossref = {conf/iccs/2006}, editor = {Uta Priss and Simon Polovina and Richard Hill}, month = {July}, pages = {241-254}, publisher = {Springer-Verlag}, series = {Lecture Notes in Artificial Intelligence}, volume = 4604, year = 2007, isbn = {3-540-73680-8}, biburl = {http://www.bibsonomy.org/bibtex/2ea581cd4026047bdf4dd0ab80ace7f28/stumme}, keywords = {formal representation fca lattice iccs 2007 taxonomies complexity analysis concept} } @inproceedings{jaeschke07organizing, title = {Organizing Publications and Bookmarks in BibSonomy}, address = {Banff, Canada}, author = {Robert Jäschke and Miranda Grahl and Andreas Hotho and Beate Krause and Christoph Schmitz and Gerd Stumme}, booktitle = {Workshop on Social and Collaborative Construction of Structured Knowledge (CKC 2007) at WWW 2007}, editor = {Harith Alani and Natasha Noy and Gerd Stumme and Peter Mika and York Sure and Denny Vrandecic}, year = 2007, url = {http://www2007.org/workshops/paper_25.pdf}, biburl = {http://www.bibsonomy.org/bibtex/2b3a5e9851647ca0a7dfb62f041872504/stumme}, keywords = {bibsonomy myown tagorapub organizing challenge BibSonomy l3s 2007} } @proceedings{alani2007workshop, title = {Workshop on Social and Collaborative Construction of Structured Knowledge (CKC 2007) at WWW 2007}, address = {Banff, Canada}, editor = {Harith Alani and Natasha Noy and Gerd Stumme and Peter Mika and York Sure and Denny Vrandecic}, year = 2007, url = {http://www2007.org/workshop-W7.php}, biburl = {http://www.bibsonomy.org/bibtex/2aac9110f5a4e2e00028f0466555ce8d4/stumme}, keywords = {challenge 2007 www2007 WWW ckc2007 collaborative myown social l3s} }
