Thursday, Thomson Reuters launched Westlaw Edge, an updated, artificial intelligence-assisted legal research platform. The updates include new warnings for invalid or questionable law, litigation analytics, a tool to analyze statutory changes and an improved AI-enhanced search called WestSearch Plus. Wednesday, Thomson Reuters hosted a group of journalists at its Times Square office to demo and illustrate the new version of Westlaw. "We're swinging for the fences, we're going after harder problems," said Mike Dahn, senior vice president of Westlaw product management. Company representatives would not disclose the cost of the new offering.
