Understanding Navigability of Social Tagging Systems: Conference Paper @ CHI 2007
(2007--01--31 07:34)Abstract
Given the rise in popularity of social tagging systems, it
seems only natural to ask how efficient is the organically
evolved vocabulary in describing any underlying document
objects? Does this distributed process really provide a way
to circumnavigate the traditional categorization problem
with ontologies? We analyze a social tagging site, namely
del.icio.us, with information theory in order to evaluate the
efficiency of this social tagging site for navigation to
information sources. We show that over time, del.icio.us is
becoming harder and harder to navigate and provide an
evaluation metric, namely entropy, that can be used to
evaluate and drive system design choices.
