Thomson Reuters on Monday released Precedent Analytics, a new feature to the Westlaw Edge research platform.

The new feature pulls from 8 million federal and 150 million state dockets to build judicial profiles that show what cases a specific judge cites, what jurisdiction those cases are from and how they rule on 23 different motions, like transfer of venue, sanctions and consolidation.

“It’s helping make for a more efficient research scenario,” says Jeff Arvidson, director of product management at Thomson Reuters.

Westlaw Edge users will automatically have access to the new feature, which combs more than 500 million cases to show citing relationships. The user is able to drill down from top level issues like civil procedure into more specific areas of law. Each area of law in the feature is tethered to existing Westlaw infrastructure, like key numbers and flags indicating overturned or implicitly overturned precedent.

“Understanding which cases judges cite to most often by topic can be incredibly important for brief writing and effective advocacy,” Mike Dahn, senior vice president of Westlaw Product Management, said in a press release. “Only Westlaw Edge enables litigators to see this information by topic with the most sophisticated topical classification of U.S. law, the West Key Number System.”

Westlaw Edge was released in July to be a next generation of artificial intelligence and legal research. At the time, the platform included 100 million state dockets and 13 types of motions.
