In such systems users are setting up lightweight conceptual structures called folksonomies. The reason for their immediate success is the fact that no specific skills are needed for participating. At the moment, however, 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.Wed Feb 08 00:00:00 CET 2012JSW122500-2507Unleashing the Potential Impact of Nonessential Self-contained Software Units and Flexible Precedence Relations upon the Value of Software.62011dblp Tue Feb 07 00:00:00 CET 2012JSW1186-195Evaluating the Efficiency in which Risk is Managed in a Portfolio of IT Projects: A Data Envelopment Analysis Approach.72012dblp Tue Feb 07 00:00:00 CET 2012GfKlconf/gfkl/2010319-327Studies in Classification, Data Analysis, and Knowledge OrganizationIdentifying Artificial Actors in E-Dating: A Probabilistic Segmentation Based on Interactional Pattern Analysis.2010dblp Fri Feb 03 00:00:00 CET 2012Financial Cryptographyconf/fc/2011235-249Lecture Notes in Computer SciencehPIN/hTAN: A Lightweight and Low-Cost E-Banking Solution against Untrusted Computers.70352011dblp Wed Feb 01 00:00:00 CET 2012EUROCAST (1)conf/eurocast/2011-1153-160Lecture Notes in Computer ScienceImplementing the Universal Virtual Computer.69272011dblp Fri Jan 27 14:10:42 CET 2012Laermminderung in Schulen2007Wahrnehmung und wirkung Wed Jan 25 00:00:00 CET 2012ISWCSconf/iswcs/2011246-250Estimating mutual information in genetics.2011dblp Tue Jan 24 00:00:00 CET 2012GLOBECOMconf/globecom/20111-5GeoDTN: Geographic Routing in Disruption Tolerant Networks.2011dblp Tue Jan 24 00:00:00 CET 2012GLOBECOMconf/globecom/20111-6A Link Quality Inference Model for IEEE 802.15.4 Low-Rate WPANs.2011dblp Fri Jan 20 00:00:00 CET 2012LICSconf/lics/2011269-278Ackermannian and Primitive-Recursive Bounds with Dickson's Lemma.2011dblp Thu Jan 19 12:34:45 CET 2012Berlin / HeidelbergThe VLDB Journaldec6849--875The Social Bookmark and Publication Management System BibSonomy192010bibsonomy bookmark publication sharing social system Social resource sharing systems are central elements of the Web 2.0 and use the same kind of lightweight knowledge representation, called folksonomy. Their large user communities and ever-growing networks of user-generated content have made them an attractive object of investigation for researchers from different disciplines like Social Network Analysis, Data Mining, Information Retrieval or Knowledge Discovery. In this paper, we summarize and extend our work on different aspects of this branch of Web 2.0 research, demonstrated and evaluated within our own social bookmark and publication sharing system BibSonomy, which is currently among the three most popular systems of its kind. We structure this presentation along the different interaction phases of a user with our system, coupling the relevant research questions of each phase with the corresponding implementation issues. This approach reveals in a systematic fashion important aspects and results of the broad bandwidth of folksonomy research like capturing of emergent semantics, spam detection, ranking algorithms, analogies to search engine log data, personalized tag recommendations and information extraction techniques. We conclude that when integrating a real-life application like BibSonomy into research, certain constraints have to be considered; but in general, the tight interplay between our scientific work and the running system has made BibSonomy a valuable platform for demonstrating and evaluating Web 2.0 research.Wed Jan 18 11:59:19 CET 2012Naturschutz und Landschaftsplanung9$\backslash$10444--451Hybridisierung zwischen Neophyten und heimischen Pflanzenarten in Deutschland- Untersuchungen zu H{\"a}ufigkeit und zum Gef{\"a}hrdungspotential2008imported Tue Jan 17 10:20:59 CET 2012HeidelbergThe Semantic Web: Research and ApplicationsJune411-426Lecture Notes in Computer ScienceInformation Retrieval in Folksonomies: Search and Ranking40112006folkrank folksonomies ranking Social bookmark tools are rapidly emerging on the Web.
