The paper "The Structure of Collaborative Tagging Systems" by Scott A. Golder and Bernardo A. Huberman analyzes the structure and dynamics of collaborative tagging systems, particularly focusing on Del.icio.us. The authors explore regularities in user activity, tag frequencies, types of tags used, and bursts of popularity in bookmarking. They also present a dynamical model that predicts stable patterns in tag usage, attributing these patterns to imitation and shared knowledge. The study reveals that while users vary significantly in the number and types of tags they use, stable patterns emerge in tag proportions, indicating a consensus among users. This stability is explained by a stochastic urn model, where the addition of new tags stabilizes over time. The paper concludes by discussing the potential uses of collaboratively generated data and the value of collaborative tagging systems in organizing and sharing content.The paper "The Structure of Collaborative Tagging Systems" by Scott A.
