Abstract. EulerView incorporates a non-hierarchical classification structure to enable enhanced resource management. We apply the EulerView concept to the use of urls, constructing eli.icio.us which is a tool that realizes the EulerView concept and integrates it with del.icio.us. Currently, in del.icio.us, users can tag urls and browse for similar urls and the results can be displayed via an alphabetically sorted tag cloud. As well as facilitating easy tag management, using an EulerView display has the advantage that the user can use this representation for both tagging urls and for searching or browsing tasks, thus reducing any cognitive difficulties of users due to interacting with multiple representations.
