Abstract: Westlaw Edge, a new legal research platform from Westlaw, was launched in 2018. The three AI-enabled features that launched with Westlaw Edge are KeyCite Overruling Risk, Litigation Analytics, and WestSearch Plus. Keycite Overruling Risk uses NLP and machine learning to warn users when a point of law in a case may have been implicitly undermined based on a prior decision, when that prior citation has no direct citation relationship to the at-risk case. Litigation Analytics allows users to access valuable metadata extracted from legal dockets about the legal actions carried out by parties, lawyers, law firms, and judges presiding over cases. WestSearch Plus is a non-factoid Question Answering system that provides legally correct, jurisdictionally relevant, and conversationally responsive answers to user-entered questions in the legal domain. Added AI-enabled features are set to launch on the Westlaw Edge platform in 2019. It is available for demo at ICAIL 2019.
