用多智能体模拟电商纠纷裁决,提升判断准确性和公平性。
CyberJurors: A Multi-Agent Simulation Task for E-Commerce Disputes Verdict

- 构建四阶段推理链,拆解纠纷证据逻辑关系。
- 通过多轮讨论与投票机制,减少裁判偏见,匹配真实裁决结果。
- 适用于需要公平、可解释裁决的电商平台与司法辅助系统。
电商平台开始招募众包陪审员处理海量交易纠纷。与正式法律判决不同,电商纠纷裁决需从冗余、多轮、多模态证据中提取关键线索,并在平台特定规则下作出决策。现有方法难以应对这一挑战。为此,我们提出首个电商纠纷裁决任务(EDV),并构建包含6000个真实案例的多模态基准数据集VerdictBench,用于反映众包陪审员的决策。在此基础上,我们提出CyberJurors多智能体框架:个体层面采用「个体裁决思维链」将任务分解为四个结构化推理阶段,实现细粒度线索感知和因果逻辑澄清;集体层面设计「陪审团共识裁决」机制,模拟多轮讨论与投票,并引入判例以缓解对任一方的认知偏见。在VerdictBench上的实验表明,CyberJurors优于当前最先进的大模型、多模态大模型及法庭模拟器,且与真实陪审员投票模式更一致。代码与数据集已开源。
原文摘要 · Abstract (English)
E-commerce platforms have begun recruiting crowdsourced jurors to adjudicate massive volumes of transaction disputes. Unlike formal legal judgment, E-commerce dispute verdicts require grounding pivotal clues from redundant, multi-round, multimodal evidence and making decisions under flexible platform-specific conventions. These characteristics render existing methods insufficient for this scenario. To bridge this gap, we introduce a pioneering task, E-commerce Dispute Verdicts (EDV), and present VerdictBench, a multimodal benchmark comprising 6,000 real-world cases designed to reflect crowdsourced jury decisions. Building upon this, we propose CyberJurors, a multi-agent framework to clarify the dispute logic and regulate the verdict process. At the individual level, Individual Verdict Chain-of-Thought decomposes the EDV task into four structured reasoning stages, enabling fine-grained clue perception and clarifying causal logic between pivotal clues and the dispute focus. At the collective level, Jury Consensus Verdict simulates multi-round discussion and voting among jurors, while incorporating verdict precedents to mitigate cognitive biases toward either disputant. Experiments on VerdictBench show that CyberJurors outperforms state-of-the-art LLMs, MLLMs, and court simulators, while achieving stronger alignment with real-world jury voting patterns.
