SyLeR's Core Approach

SyLeR integrates a novel tree-structured hierarchical retrieval mechanism with a two-stage reinforcement fine-tuning process. This enables Large Language Models (LLMs) to engage in explicit syllogistic legal reasoning, forming comprehensive major premises from legal statutes and precedent cases, deriving minor premises from specific case facts, and concluding with logically sound legal answers. This structured approach significantly enhances accuracy, explainability, and trustworthiness in legal AI outputs.

Advanced Legal Knowledge Integration

SyLeR's unique tree-structured hierarchical retrieval mechanism organizes legal knowledge by connecting relevant statutes with their corresponding precedent cases. This preserves the inherent interpretive relationships between general legal principles and specific applications. By combining statutes and cases into a comprehensive major premise, SyLeR provides LLMs with a robust and logically sound foundation for reasoning, overcoming the limitations of single-source or unstructured data retrieval.

Refining Reasoning with Reinforcement Learning

The framework employs a two-stage reinforcement fine-tuning strategy. A warm-up stage uses supervised fine-tuning with GPT-40 generated reasoning paths to establish a foundational understanding of syllogistic structure. This is followed by a reinforcement learning (RL) stage, where the Proximal Policy Optimization (PPO) algorithm refines the model's ability to generate diverse, logically sound reasoning paths. A structure-aware reward mechanism evaluates major premise alignment, minor premise consistency, and conclusion correctness, ensuring strict adherence to the syllogistic format.

SyLeR vs. Traditional Legal AI: A Comparative Overview

Feature Traditional LLMs/RAG SyLeR Framework
Reasoning Type
  • Implicit, often unstructured
  • Lacks clear major/minor premises
  • Explicit Syllogistic Reasoning
  • Structured Major Premise, Minor Premise, Conclusion
Knowledge Integration
  • Basic RAG (retrieves isolated documents)
  • Limited understanding of legal interconnections
  • Hierarchical Statute-Case Retrieval
  • Preserves interpretive connections
Adaptability
  • Often domain-specific, limited cross-domain transfer
  • Struggles with diverse language contexts
  • Cross-Domain (layperson to practitioner)
  • Multi-Language (Chinese, French)
Explainability & Trust
  • Low transparency of reasoning process
  • Reduced user trust due to implicit steps
  • High transparency (explicit reasoning paths)
  • Enhanced trustworthiness and justification
+18% Average Accuracy Increase Across Legal QA Tasks

Real-World Legal Query Solved by SyLeR

Consider a user querying about social insurance premiums after leaving a company. Traditional LLMs might provide generic advice or simply rephrase legal texts. SyLeR, however, excels by first performing tree-structured hierarchical retrieval to find relevant statutes (e.g., Article 58 of the Social Insurance Law) and pertinent precedent cases, forming a comprehensive major premise.

It then formulates a precise minor premise directly from the user's specific facts. This leads to a clear, actionable conclusion, detailing the user's rights to complain or negotiate and, if unsuccessful, the option for arbitration according to law. This structured approach ensures a highly trustworthy, explainable, and legally sound response, setting a new standard for legal AI.
