Archive-It, a subscription service from the Internet Archive, allows users to create,
maintain, and view digital collections of web resources. The current interface of
Archive-It is largely text-based, supporting drill-down navigation using lists of URIs.
While this interface provides good searching capabilities, it is not very efficient for
browsing. In the absence of keywords, a user has to spend large amount of time trying
to locate a webpage of interest. In order to provide a better visual experience to
the user, we have studied the underlying characteristics of Archive-It collections and
implemented six different visualizations (treemap, time cloud, bubble chart, image
plot, timeline and wordle), each highlighting one or more of the underlying characteristics
of the collection. Archive-It supports grouping of webpages into categories,
however, it does not enforce its usage. As a result there are many collections with
missing or improper grouping. For such collections, we present a method of grouping
webpages based on a set of pre-defined rules.
