As a “next evolution” of the Westlaw Edge research platform, Thomson Reuters announced today the addition of a “Precedent Analytics” feature, which fully integrates into platform’s Litigation Analytics component. Jeff Arvidson, director of product management at Thomson Reuters, said the new feature will allow users to see and analyze “the cases and court judges rely on when they are drafting opinions.”

With Precedent Analytics, users can select a state or federal judge to see her or his past rulings in a specific area of law, then determine what cases and courts were most cited or referenced in those rulings. The feature also includes a heat map that visually displays the federal districts or circuits, or all 50 state courts that a particular judge often cites from.
