Outline

This paper presents a framework to overcome the limitations of large-scale language models (LLMs) in legal dispute analysis for intelligent legal support systems. To address the difficulties of understanding complex legal concepts, maintaining inference consistency, and accurately citing legal grounds, we propose a framework combining multidimensional knowledge graphs and prompt engineering. It consists of a three-level hierarchical prompt structure (task definition, background knowledge, and inference guidance) and a three-layer knowledge graph (legal ontology, representation, and instance layers), and utilizes four support methods for accurate legal concept retrieval: direct code matching, semantic vector similarity, ontology path inference, and vocabulary segmentation. The experimental results show that the sensitivity (9.9%-13.8%), specificity (4.8%-6.7%), and citation accuracy (22.4%-39.7%) are significantly improved, providing a new technical method for intelligent legal support systems by improving legal analysis and judicial logic understanding.

Takeaways, Limitations

Takeaways:
Possibility of Improving LLM-Based Legal Dispute Analysis Performance by Combining Multidimensional Knowledge Graph and Prompt Engineering
Proposing effective support methods to improve legal concept retrieval accuracy (direct code matching, semantic vector similarity, ontology path inference, vocabulary segmentation)
Providing a new technological approach to developing intelligent legal assistance systems
Measurable performance improvements in sensitivity, specificity, and citation accuracy
Limitations:
Further verification of the generalizability of the presented framework and its applicability to various areas of law is needed.
Consideration should be given to maintaining the completeness and up-to-dateness of the knowledge graph used.
Possible dependence on a particular language or legal system
Further improvements are needed through review and feedback from actual legal experts.
