    Systems Engineering Student Makes Case at Harvard Law School for Electronic Research Assistant

    June 28, 2019

    Faraz Dadgostari, who is working on his Ph.D. in systems engineering at the University of Virginia, gave a talk at Harvard Law School titled “Learning Knowledge Search Techniques in the Law.” The project is a collaboration with Michael Livermore, a UVA Law professor and Peter Beling, professor and associate chair for research in the Department of Engineering Systems and Environment at UVA.

    Their work combines natural language processing and reinforcement learning to replicate how attorneys search and select from legal cases when they are developing arguments for given legal questions. The team’s approach learns from the in-text citations in U.S. Supreme Court opinions, leading to algorithms that search for the smallest set of relevant cases required for the legal arguments the lawyer is trying to make, Faraz said.

    The work introduces a novel theory of legal search and new reinforcement learning formulations. The project is supported in part by the Center for Visual and Decision Informatics, a National Science Foundation Industry/University Cooperative Research Center. Professor Beling is the center’s UVA site director.
