"The debate within the Web community over the optimal means
by which to organize information often pits formalized classications
against distributed collaborative tagging systems. A number
of questions remain unanswered, however, regarding the nature of
collaborative tagging systems including whether coherent categorization
schemes can emerge from unsupervised tagging by users.
This paper uses data from the social bookmarking site del.icio.us to
examine the dynamics of collaborative tagging systems. In particular,
we examine whether the distribution of the frequency of use
of tags for popular sites with a long history (many tags and many
users) can be described by a power law distribution, often characteristic
of what are considered complex systems. We produce a
generative model of collaborative tagging in order to understand
the basic dynamics behind tagging, including how a power law distribution
of tags could arise. We empirically examine the tagging
history of sites in order to determine how this distribution arises
over time and to determine the patterns prior to a stable distribution.
Lastly, by focusing on the high-frequency tags of a site where
the distribution of tags is a stabilized power law, we show how tag
co-occurrence networks for a sample domain of tags can be used
to analyze the meaning of particular tags given their relationship to
other tags."
The paper shows that the tags users choose are not chaotic, but rather quickly converge to a common descriptive set of tags that is almost unchanging over time. Perhaps once the tags have stabilized, coherent URI-based identification schemes could emerge?
Nice paper, thanks. Categories / tags / subjects / topics / issues ... that's what I'm working with right now. p.s. sure would be nice if the email notification included the source URL. I'm far more likely to download the PDF when I see something like www2007.org/paper635.pdf
The World Federation of UN Associations is an independent, non-governmental organization with Category One Consultative Status at the Economic and Social Council (ECOSOC) and consultative or liaison links with many other UN organizations and agencies. The Millennium Project functions under the auspices of WFUNA.
The Millennium Project of WFUNA is a global participatory futures research think tank of futurists, scholars, business planners, and policy makers who work for international organizations, governments, corporations, NGOs, and universities. The Millennium Project manages a coherent and cumulative process that collects and assesses judgements from its several hundred participants to produce the annual "State of the Future", "Futures Research Methodology" series, and special studies such as the State of the Future Index, Future Scenarios for Africa, Lessons of History, Environmental Security, Applications of Futures Research to Policy, and a 700+ annotated scenarios bibliography.
We propose a biologically and physically plausible model for ants and pheromones, and show this model to be sufficiently powerful to simulate the computation of arbitrary logic circuits. We thus establish that coherent deterministic and centralized computation can emerge from the collective behavior of simple distributed markovian processes as those followed by ants.
