Outline

This paper highlights that structuring legal norms in a machine-readable manner is essential for building advanced AI and information retrieval systems, such as Legal Knowledge Graphs (LKGs). Based on the FRBR model, we propose a basic framework for mapping legal operations (embodied as Norm nodes) to the schema.org/Legislation vocabulary. Using the Normas.leg.br portal as a case study, we demonstrate how to describe operation entities using JSON-LD, taking into account stable URN identifiers, inter-norm relationships, and lifecycle properties. This structured and formal approach provides a first step toward building deterministic and verifiable knowledge graphs, which can overcome the limitations of purely probabilistic models and serve as a formalized "ground truth" for legal AI applications.

Takeaways, Limitations

Takeaways:
A systematic approach for machine-readable structuring of legal norms is presented.
Provides an interoperable framework leveraging the FRBR model and the schema.org/Legislation vocabulary.
Clear and structured representation of legal work entities using JSON-LD.
Laying the foundation for building a deterministic and verifiable legal knowledge graph.
Overcoming the limitations of purely probabilistic models and enhancing legal AI applications.
Limitations:
Further research is needed on the practical applicability and scalability of the proposed framework.
Applicability to various legal systems and languages needs to be verified.
The possibility of not fully resolving the complexity and ambiguity of legal norms.
Limitations of generalizability of case studies confined to the Normas.leg.br portal.
