Visualizing Legal Information

West Publishing produces paper and online versions of cases, statutes, and other legal information. Since searches often are difficult to compose and produce complex results, advanced interfaces that apply information visualization may help. This project is creating inspirational prototypes using existing tools such as LifeLines, Spotfire, WebTOC, and Dotfire. West's hierarchy of legal topics called Key Numbers, provides a fruitful framework for visualization of search results, as do temporal, geographic, and link structures Our initial prototypes will be evaluated and the most promising alternatives will be refined and tested with legal information specialists.

Latest prototypes:
