Guidelines for the Annotation and Visualization of Legal Argumentation Structures in Chinese Judicial Decisions
This Guideline aims to construct a systematic, operational, and reproducible annotation framework for legal argumentation structures, designed to reveal the logical structure of judicial reasoning in court decisions. Grounded in legal argumentation theory, the Guideline establishes formal representation rules and diagrammatic standards through clearly defined categories of proposition types and inter-propositional relation types. It further incorporates rigorous annotation procedures and consistency control mechanisms, thereby providing a reliable data foundation for subsequent automated analysis, structural mining, and model training.
Executive Impact & Core Findings
The proposed framework delivers robust methodological foundations and technical standards for quantitative analysis and computational modeling of judicial reasoning. By structuring complex legal arguments, it significantly enhances the explainability and auditability of AI systems in legal applications, moving beyond mere outcome prediction to transparent, verifiable reasoning.

Driving Explainable Legal AI
In judicial adjudication, legal reasoning occupies a central position. The core of legal evaluation lies not merely in the conclusion of a judgment, but in whether the reasons supporting that conclusion are sufficient, whether the reasoning process is justified, and whether the argumentation is acceptable. This guideline aims to propose a structured annotation and visualization framework for legal argumentation in the reasoning sections of Chinese judicial decisions, designed to provide a unified, reproducible, and extensible operational standard for manual annotation, dataset construction, and related research.
Key objectives include defining fundamental elements and their labeling scheme, specifying relation types and annotation rules, representing overall structure graphically, and establishing a unified foundation for future research and applications.
Categorizing Judicial Judgments
The Guideline distinguishes four basic proposition types based on two dimensions: 'particular' vs. 'general', and 'fact' vs. 'norm'. These are: Particular Factual Judgment (SF), General Factual Judgment (GF), Particular Normative Judgment (SM), and General Normative Judgment (GM).
GM plays the most central role in legal argumentation and is further divided into six sub-types: statutory provisions, legal interpretation, contracts and contract interpretation, customs and industry practices, morality and value principles, and other normative judgments.
Mapping Logical Connections
Five core inter-propositional relation types are defined to capture logical connections: Support (S), Attack (A), Joint (J), Match (M), and Identity (I). These relations are designed to reveal asserted logical connections in judicial reasoning.
Support and attack capture positive/negative argumentative directions, joint relations characterize conjunctive structures, match relations describe correspondence between general rules and specific facts, and identity relations handle semantic equivalence of propositions.
Visualizing Argument Structures
The Guideline introduces unified visualization standards: proposition nodes are represented by rectangles, relation nodes by circles. Different circle styles distinguish support (solid), attack (hollow), and joint/match ('+') relations. Identity is represented by a slash '/' within a rectangular node.
For nested structures, diagrams are constructed layer by layer from the innermost relation outward, ensuring independence and hierarchical clarity of each relational node for readability and verifiability.

| Feature | Match Relation | Joint Relation |
|---|---|---|
| Purpose | Connects normative elements with case facts. | Characterizes conjunctive support for a conclusion. |
| Propositions Involved | General Judgments & Particular Judgments. | Propositions of the same type (typically). |
| Structure | Elements of a legal norm correspond to relevant facts. | Multiple propositions jointly necessary to form a complete justification. |
Case Study: Argumentation Structure in Original Judgment (Document I)
The provided Document I (Civil Judgment) serves as a comprehensive example demonstrating the full annotation workflow. It illustrates how propositions are segmented and typed (e.g., GM-L for legal norms, SM for particular normative judgments, SF for particular factual judgments), and then how inter-propositional relations (Joint, Match, Support) are identified and formally expressed. The final stage showcases the construction of argument diagrams, providing a clear visual representation of the court's reasoning for both positive claims and dismissed requests (e.g., the additional RMB 600 claim). This example highlights the practical application of the Guideline's systematic framework.

Your Enterprise AI Implementation Roadmap
Our proven four-stage workflow ensures a smooth, consistent, and verifiable implementation of legal argumentation AI, from foundational training to final deployment.
Annotator Training & Guideline Study
Standardized training for all annotators on definitions, distinction criteria, and common ambiguity scenarios, followed by independent study and confirmation of understanding.
Pilot Annotation & Guideline Calibration
Independent pilot annotations by multiple annotators to test operational feasibility, identify high disagreement rates, and refine or consolidate annotation rules iteratively.
Formal Annotation & Dual Independent Annotation
Each text is independently annotated by at least two annotators following finalized guidelines, with results stored in structured form for alignment and comparison.
Conflict Resolution & Expert Review
Automatic/semi-automatic comparison identifies inconsistencies; routine disagreements are resolved through discussion, while core conceptual disputes involve project leads or domain experts.
