Group 1 - The fifth "Xiaobao Gong Cup" university legal empirical analysis essay competition award ceremony was held in Guangzhou, marking a significant step in the application of legal AI in China [1] - The event featured the launch of China's first vertical large model in the legal field, the "Xiaobao Gong Legal Content Large Model," developed by a team led by Professor Wang Yanling from South China Normal University [1] - The model integrates over 200 million judicial documents and more than 4.2 million legal regulations, utilizing a dual-engine architecture of "advanced general large model + professional vertical large model" [1] Group 2 - Legal experts indicate that the proliferation of legal AI will help alleviate the uneven distribution of legal service resources in China, where 700,000 practicing lawyers are mainly concentrated in developed eastern regions [2] - The large model's standardized application is expected to demonstrate effectiveness in key areas such as administrative reconsideration, prosecutorial supervision, and contract compliance [2]

Core Insights - The article presents a comprehensive review of the application of Large Language Models (LLMs) in the legal field, introducing an innovative dual perspective classification method that integrates legal reasoning frameworks with professional ontology [1][3][5] - It highlights the advancements of LLMs in legal text processing, knowledge integration, and formal reasoning, while also addressing core issues such as hallucinations, lack of interpretability, and cross-jurisdictional adaptability [1][5][12] Group 1: Technological Advancements - Traditional legal AI methods are limited by symbolic approaches and small model techniques, facing challenges such as knowledge engineering bottlenecks and insufficient semantic interoperability [6][8] - The emergence of LLMs, powered by Transformer architecture, has successfully overcome the limitations of earlier systems through context reasoning, few-shot adaptation, and generative argumentation capabilities [6][12] - The legal sector's demand for complex text processing, multi-step reasoning, and process automation aligns well with the emerging capabilities of LLMs [8][12] Group 2: Ethical and Governance Challenges - The practical application of technology in the legal field is accompanied by ethical risks, such as the amplification of biases and the weakening of professional authority, necessitating a systematic research framework to integrate technology, tasks, and governance [3][8][11] - The review systematically analyzes ethical challenges faced by legal practitioners, including technical ethics and legal professional responsibilities, expanding user-centered ontology research for LLM deployment [11][12] Group 3: Research Contributions - The study employs an innovative dual perspective framework that combines legal argumentation types with legal professional roles, significantly advancing research in the field [9][12] - It constructs a legal reasoning ontology framework that aligns the Toulmin argument structure with LLM workflows, integrating contemporary LLM advancements with historical evidence research [9][10] - A role-centered deployment framework for LLMs is proposed, merging litigation and non-litigation workflows to meet the demand for smarter tools in legal practice [10][12] Group 4: Future Directions - Future research should prioritize multi-modal evidence integration, dynamic rebuttal handling, and aligning technological innovations with legal principles to create robust and ethically grounded legal AI [13] - The article advocates for a legal profession-centered strategy, positioning LLMs as supportive tools rather than decision-makers, ensuring human oversight at critical junctures [13]
