    Exploring Collections of Tagged Text for Literary Scholarship
    (The Eurographics Association and Blackwell Publishing Ltd., 2011) Correll, Michael; Witmore, M.; Gleicher, M.; H. Hauser, H. Pfister, and J. J. van Wijk
    Modern literary scholars must combine access to vast collections of text with the traditional close analysis of their field. In this paper, we discuss the design and development of tools to support this work. Based on analysis of the needs of literary scholars, we constructed a suite of visualization tools for the analysis of large collections of tagged text (i.e. text where one or more words have been annotated as belonging to a specific category). These tools unite the aspects of the scholars' work: large scale overview tools help to identify corpus-wide statistical patterns while fine scale analysis tools assist in finding specific details that support these observations. We designed visual tools that support and integrate these levels of analysis. The result is the first tool suite that can support the multilevel text analysis performed by scholars, combining standard visual elements with novel methods for selecting individual texts and identifying represenative passages in them.

    TextDNA: Visualizing Word Usage with Configurable Colorfields
    (The Eurographics Association and John Wiley & Sons Ltd., 2016) Szafir, Danielle Albers; Stuffer, Deidre; Sohail, Yusef; Gleicher, Michael; Kwan-Liu Ma and Giuseppe Santucci and Jarke van Wijk
    Patterns of words used in different text collections can characterize interesting properties of a corpus. However, these patterns are challenging to explore as they often involve complex relationships across many words and collections in a large space of words. In this paper, we propose a configurable colorfield design to aid this exploration. Our approach uses a dense colorfield overview to present large amounts of data in ways that make patterns perceptible. It allows flexible configuration of both data mappings and aggregations to expose different kinds of patterns, and provides interactions to help connect detailed patterns to the corpus overview. TextDNA, our prototype implementation, leverages the GPU to provide interactivity in the web browser even on large corpora. We present five case studies showing how the tool supports inquiry in corpora ranging in size from single document to millions of books. Our work shows how to make a configurable colorfield approach practical for a range of analytic tasks.
