  1. IR UI H. Lally Singh 3/27/2003

  2. Papers Discussed • A Scrollbar-based Visualization for Document Navigation, Donald Byrd • Improving User Performance on Boolean Queries, John F. Pane, Brad A. Myers • Get both from “ACM Article Search” link in lib.vt.edu’s “article search” section.

  3. 1. Scrollbar Visualization • Displays search terms’ locations in text in the scrollbar. • Small colored dots represent each terms’ incidences in text. • Different color for each term’s dots.

  4. 1. Scrollbar Visualization Example Incidences of Terms in Text Search Terms

  5. 2. Improving Boolean Queries • Use a graphical notation to describe boolean queries • A set of boxes, each with a clause. • Conjunction represented with rows of boxes. • Disjunction represented by horizontally adjacent boxes. • Tests show ~10% improvement in user ability to generate queries this way versus standard text. potato not oranges glue paste manufacturing potato and (not oranges) and (glue or paste) and manufacturing

  6. Conclusions • Both help IR systems suck less • Both help user get out of sucky IR system faster • Both require client-side intelligence • Could be implemented for the web via Flash • Probably won’t see it in Google
