We develop the ResultMap concept, a treemap-based visualization system that we have applied to keyword search engine and faceted classification data environments, and present the results of their empirical evaluation.-We organize this work as follows: Chapter 1 provides an introduction to our problem area, motivates our general approach of leveraging hierarchical structure (via ResultMaps) for context, and proposes a thesis statement and corresponding research questions.

Chapter 2 discusses related work, and includes a survey and design characterization of faceted navigation tools. Chapter 3 defines the key visual and interactive features of the ResultMap concept and justifies their basic design.-Chapter 4 presents our implementation and evaluation of ResultMaps applied to digital library search engine result pages (SERPs). Chapter 5 consists of two major portions: a presentation of our formal data and query models for faceted environments and our implementation and evaluation of ResultMaps in a faceted UI context.

In Chapter 6 we conclude---based on our results from Chapter 4 and Chapter 5---with a set of principles for designing both visual search interfaces themselves and designing their evaluation. We finish with suggestions for future research in this area.
