构建针对家暴案件的法律知识图谱,助力司法决策智能化。
Automated Creation of the Legal Knowledge Graph Addressing Legislation on Violence Against Women: Resource, Methodology and Lessons Learned
- 采用自下而上与大模型结合的自动化方法构建图谱
- 基于欧盟法院公开判例,完成结构化数据提取与语义增强
- 可支持复杂查询,适合法律AI与预测司法研究者使用
法律决策需要全面详尽的立法背景知识及最新判例信息。法律知识图谱(KG)可作为高效获取法律信息的工具,支持查询、推理与机器学习应用,有望成为预测性司法系统的核心知识组件。然而,法律领域高质量知识图谱仍稀缺。为此,本文针对家暴案件构建了一个法律知识图谱,并提出两种互补的自动化构建方法:一种是定制化的自下而上方法,另一种是基于大语言模型的新方案。两者均从欧洲法院公开判例出发,通过结构化数据抽取、本体构建与语义增强,生成面向家暴案件的图谱。经由能力验证问题评估后,结果表明该图谱可提升法律信息的人机可访问性,支持复杂查询,并有望被用于面向预测正义的机器学习工具中。
原文摘要 · Abstract (English)
Legal decision-making process requires the availability of comprehensive and detailed legislative background knowledge and up-to-date information on legal cases and related sentences/decisions. Legal Knowledge Graphs (KGs) would be a valuable tool to facilitate access to legal information, to be queried and exploited for the purpose, and to enable advanced reasoning and machine learning applications. Indeed, legal KGs may act as knowledge intensive component to be used by pre-dictive machine learning solutions supporting the decision process of the legal expert. Nevertheless, a few KGs can be found in the legal domain. To fill this gap, we developed a legal KG targeting legal cases of violence against women, along with clear adopted methodologies. Specifically, the paper introduces two complementary approaches for automated legal KG construction; a systematic bottom-up approach, customized for the legal domain, and a new solution leveraging Large Language Models. Starting from legal sentences publicly available from the European Court of Justice, the solutions integrate structured data extraction, ontology development, and semantic enrichment to produce KGs tailored for legal cases involving violence against women. After analyzing and comparing the results of the two approaches, the developed KGs are validated via suitable competency questions. The obtained KG may be impactful for multiple purposes: can improve the accessibility to legal information both to humans and machine, can enable complex queries and may constitute an important knowledge component to be possibly exploited by machine learning tools tailored for predictive justice.
