ResultMap demo http://hcc.cc.gatech.edu/ Treemap based visualization in conjunction

with digital library search facility Showing search results in the context of the

full information space

Problem statements

Hierarchy is a central component for browsing online repositories in many search systems.

Conventional search relevancy reports make users limit their searches to certain sections of a hierarchy

Hierarchies are underutilized in the context of repository search

Exploratory search systems

In Browsing and exploratory systems, it is important to employ faceted metadata Data Characteristics organized by a set of ortho

gonal attributes For example, Flamenco (http://flamenco.berkel

ey.edu)

Visualization with hierarchical data More easy to read interface

By interacting with both graphics and result cases, users can more easily explore the information.

Easy way of linking the attributes of specific items Glance-able overview of the entire document spac

e Making both cluster and outlier detection straightf

orward Coloring by document type

Future direction of this research

User performance evaluation System enhancements

Integration with a faceted browsing system Graphical enhancements

Each faceted Resultsmaps in multifaceted hierarchy

Implications to our research When implementing exploratory search system, vis

ual support is important Visual cue to users to navigate information space

Helpful to grasp dominate trend of information System calculated weights can be applied to the Re

sultMap in a meaningful way How can multi-faceted information be displayed in

a hierarchy-based visualization at the same time?
