Evolution of Artificial Intelligence within LegalTech-A Literature Review
Abstract
Purpose – This research aims to provide an overview of the current state of research regarding the possible future use of AI in the legal domain and its impact.
Method – This research follows the guidelines proposed by Kitchenham and Charters (2007) for a systematic literature review.
Results – This study presents the current state of research on the use of artificial intelligence in LegalTech. This research shows that AI applications in the legal domain have existed for many years, but interest has grown sharply since around 2016. Across the literature, AI is used in a wide range of legal areas, and most papers focus on a single domain. A significant amount of research examines the justice systems. This study reveals that two major AI technologies are dominating the legal domain, namely, machine learning and natural language processing.
Conclusion – This review examines 91 studies and provides an overview of how AI is currently used in the legal domain. Most studies focus on a single application domain. The reported benefits of using AI include improved efficiency and accuracy, reduced costs, and the ability to process large datasets without fatigue or human bias. However, the review also identifies major challenges such as liability, privacy risks, system complexity, and high implementation costs.
Recommendations – AI can be used to enhance the legal process and activities, but cannot yet replace human expertise.
Research Implications – Results show that current research highly focuses on specific legal domains, for example, lawyers, law firms, and judicial decision-making. Future studies can be open to other areas like legal education and public sector legal services.
Practical Implications – The findings demonstrate that legal practitioners and law firms can benefit by adopting AI to enhance efficiency, accuracy, and decision-making.
