Vielen Dank an alle meine treuen Leser, Kommentatoren und Verlinker ;) Ohne Euch hätte ich nie so lange durchgehalten. Doch jetzt ist Schluss mit dem WWWorker:

Semiotic dynamics and collaborative tagging — Cattuto et al. 104 (5): 1461 — Proceedings of the National Academy of Sciences: Here we collect data from a popular system and investigate the statistical properties of tag cooccurrence. 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.
