Data informs, and in some cases controls, every aspect of modern life. Well, almost every aspect. “If you look at finance or medicine or sports, almost every other thing in the world is using data to make better decisions,” says Ed Walters. “Everything except law.” In this episode of the Modern Law Library, the ABA Journal’s Jason Tashea speaks with Walters, editor of “Data-Driven Law: Data Analytics and the New Legal Services.” The book is a collection of articles by data scientists, lawyers and technologists on a breadth of topics, including data mining, the accuracy of technology-assisted review in e-discovery and quantifying the quality of legal services.
