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

  2. 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

  3. 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

  4. Exploratory search systems • In Browsing and exploratory systems, it is important to employ faceted metadata • Data Characteristics organized by a set of orthogonal attributes • For example, Flamenco (http://flamenco.berkeley.edu)

  5. 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 space • Making both cluster and outlier detection straightforward • Coloring by document type

  6. Future direction of this research • User performance evaluation • System enhancements • Integration with a faceted browsing system • Graphical enhancements • Each faceted Resultsmaps in multifaceted hierarchy

  7. Implications to our research • When implementing exploratory search system, visual 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 ResultMap in a meaningful way • How can multi-faceted information be displayed in a hierarchy-based visualization at the same time?
