understanding about how users surf for information. Predictive Web usage
visualizations can help analysts uncover traffic patterns and usability
problems. The author describes some of the techniques those in the User
Interface Research Group at PARC have developed to visualize content
changes, linkage structures, site usage, and so on. He explores how
these techniques can be used to identify specific usability problems at
large Web sites. As part of his work, he have created a predictive
visualization model called Information Scent, in which simulated users
help uncover patterns and deficiencies in information accessibility. He
demonstrates these techniques using a prototype system called ScentViz
to illustrate how Web usage analysis can be enhanced using visualization
