ResultMaps: Search Result Visualization for Hierarchical Information Spaces
Danielle H. Lee
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?
