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

2. ResultMap demo  http://hcc.cc.gatech.edu/ 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

6. 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

7. 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)

8. 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

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

10. 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?
