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/hotho}, keywords = {2007 myown summerschool social sosbuch kdubiq folksonomy conceptual clustering bookmarking tagging} } @inproceedings{Benz07OL, title = {Position Paper: Ontology Learning from Folksonomies.}, author = {Dominik Benz and Andreas Hotho}, booktitle = {LWA 2007: Lernen - Wissen - Adaption, Halle, September 2007, Workshop Proceedings (LWA)}, crossref = {conf/lwa/2007}, editor = {Alexander Hinneburg}, pages = {109-112}, publisher = {Martin-Luther-University Halle-Wittenberg}, year = 2007, url = {http://dblp.uni-trier.de/db/conf/lwa/lwa2007.html#BenzH07}, isbn = {978-3-86010-907-6}, vgwort = {16}, date = {2007-11-16}, description = {dblp}, biburl = {http://www.bibsonomy.org/bibtex/2ad31989b2393f5d0c4e8be8dbb613141/hotho}, keywords = {myown 2007 learning ontology summerschool kdubiq folksonomy} } @inproceedings{jaschke07recommender, title = {Tag Recommendations in Folksonomies}, author = {Robert Jäschke and Leandro Balby Marinho and Andreas Hotho and Lars Schmidt-Thieme and Gerd Stumme}, booktitle = {Knowledge Discovery in Databases: PKDD 2007, 11th European Conference on Principles and Practice of Knowledge Discovery in Databases, Warsaw, Poland, September 17-21, 2007, Proceedings}, editor = {Joost N.

Here we collect data from a popular system and investigate the statistical properties of tag co-occurrence. We introduce a stochastic model of user behavior embodying two main aspects of collaborative tagging: (i) a frequency-bias mechanism related to the idea that users are exposed to each other's tagging activity; (ii) a notion of memory - or aging of resources - in the form of a heavy-tailed access to the past state of the system. Remarkably, our simple modeling is able to account quantitatively for the observed experimental features, with a surprisingly high accuracy. This points in the direction of a universal behavior of users, who - despite the complexity of their own cognitive processes and the uncoordinated and selfish nature of their tagging activity - appear to follow simple activity patterns.}, biburl = {http://www.bibsonomy.org/bibtex/2c958b2f97a0557abdb3778faa34802bb/hotho}, keywords = {kdubiq tagging analysis behaviour summerschool model} } @inproceedings{schmitz2006mining, title = {Mining Association Rules in Folksonomies}, address = {Ljubljana}, author = {Christoph Schmitz and Andreas Hotho and Robert Jäschke and Gerd Stumme}, booktitle = {Data Science and Classification (Proc.

However, CF becomes less effective when users have multiple interests, because users have similar taste in one aspect may behave quite different in other aspects. Information got from social bookmarking websites not only tells what a user likes, but also why he or she likes it. This paper proposes a division algorithm and a CubeSVD algorithm to analysis this information, distill the interrelations between different users’ various interests, and make better personalized recommendation based on them. Experiment reveals the superiority of our method over traditional CF methods.
