Text Analysis and Visualization

  • Jigsaw is a text visualization tool that was developed by John Stasko and his students at the Georgia Institute of Technology.
  • This system explores entities (people, places, dates, money) and the relationships between them.
  • Jigsaw uses several different views to present information to the user, including calender, list, graph, scatterplot, text, and time line views.
  • Each view is presented as a separate window that updates automatically with the results of various queries.

  • All views are linked by default to one another, so acting on a document or entity in one view causes all other windows that are listening to update in accordance with that action.
  • Listening can be toggled on or off in any window to preserve its state.
  • It is often helpful to actually witness the views as they update, in order to more easily see how they are changing.
  • One may find that it is necessary to use Jigsaw across four or more screens, to harness the system’s full potential.
  • This tool is especially useful in data exploration involving large collections of data and information.
  • Applications include military intelligence, law enforcement, or journalism, among many others.
