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.analysis, behaviour, kdubiq, model, summerschool, tagging, taggingsurveyConferenceProceedingsinproceedings1180904tagging, communities, vocabulary, evolution2006SenShiladLamK.ShyongRashidMamunurAlCosleyDanFrankowskiDanOsterhouseJeremyHarperMaxwellF.RiedlJohn181-190 ISBN: 1-59593-249-6 DOI: http://doi.acm.org/10.1145/1180875.1180904ACMNew York, NY, USACSCW '06: Proceedings of the 2006 20th anniversary conference on Computer supported cooperative workCSCW '06: Proceedings of the 2006 20th anniversary conference on Computer supported cooperative workhttp://portal.acm.org/citation.cfm?id=1180904A tagging community's vocabulary of tags forms the basis for social navigation and shared expression.We present a user-centric model of vocabulary evolution in tagging communities based on community influence and personal tendency.

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.2007, bookmarking, clustering, conceptual, folksonomy, kdubiq, myown, social, sosbuch, summerschool, tagging, taggingsurveyJournalArticlecattuto2007networkNetwork Properties of Folksonomies2007CattutoCiroSchmitzChristophBaldassarriAndreaServedioD.
