LegisFlow interface for Korean statutory research with interactive amendment timelines and inter-statute relationship analysis

📝Abstract

In South Korea’s statutory law system, legal research faces challenges like tracking frequent amendments and understanding complex statute relationships. LegisFlow, an innovative AI-powered system, tackles these issues with features such as interactive amendment timelines and advanced inter-statute relationship analysis. Developed based on insights from Korean legal experts, it provides intuitive visualizations and context-aware search capabilities. A user study with 10 legal professionals demonstrated that LegisFlow significantly enhances efficiency, reducing task completion times by up to 36% (e.g., 440s vs. 690s in inter-statute comparison, p = 0.022) and lowering cognitive load, with workflows streamlined by 70% fewer manual steps. LegisFlow transforms statutory law research by setting a new standard for AI-assisted tools, providing a scalable, user-centered solution for professionals in Korea and beyond.
