AI Beats Human Lawyers At Their Own Game

The robot apocalypse isn’t all bad news: A new study suggests artificial intelligence makes better lawyers than humans do.LawGeex pitted 20 experienced attorneys against a three-year-old algorithm trained to evaluate contracts. Spoiler alert: the computer won.“Few would be surprised that artificial intelligence works faster than lawyers on certain non-core legal tasks,” according to the report. “However, lawyers and the public generally believe that machines cannot match human intellect for accuracy in daily fundamental legal work.”Participants were given four hours to identify and highlight 30 proposed legal issues in five standard non-disclosure agreements (NDAs). “It is not enough to merely skim the agreements,” LawGeex Head of Data Gil Rosenblum said in a statement. “A deeper analysis is required.Lawyers and the AI, for instance, were penalized for missing an exemption relevant to the contract, or mistakenly identifying an exemption where it was irrelevant.In the end, LawGeex’s neural network achieved an average 94 percent accuracy rate, compared to the lawyers’ average of 85 percent. And while it took humans anywhere from 51 minutes to more than 2.5 hours to complete all five NDAs, the AI engine finished in 26 seconds.Score one for the technology.The AI contract review automation solution—founded in 2014—was trained using a custom-built machine- and deep-learning technology; it studied everything from software and services agreements to purchase orders and NDAs.The process is not without its complications, though. No existing computational language models could read legalese coherently, making it difficult for the machine to understand technical language. Add to that the high accuracy required in statutory AI training.That didn’t stop LawGeex, which created proprietary “languages” that helped the computer identify various concepts no matter where or how they appear in a document.Research was conducted with input from academics, data scientists, and legal and machine-learning experts, and was overseen by an independent consultant and lawyer Christopher Ray.This is, of course, not the first study to pit AI against human in the field of law. It is, however, the most evenly matched, according to LawGeex.So what does it mean for the future of litigation? Hopefully the unencumbrance of work for already-hard-working people. “For over-extended lawyers carrying out everyday contract review, this technology allows them to focus on only relevant sections of a contract, pre-validated by the AI,” the company said. “This is part of a wider technology-driven disruption [that] has already created a shift in the legal profession.”Sign up online to read more about the study—conducted in partnership with professors from Stanford University, Duke University School of Law, and the University of Southern California.last_img
