中国法律案例检索基准存在基于指控的设计缺陷

一项对中国法律案例检索(LCR)基准的新审计显示,驱动性能的主要因素并非先进的检索模型,而是基准围绕法律指控的构建方式。研究人员发现,仅通过共同的主要指控对案例进行排序,并结合基本的BM25排序,就能弥补简单系统和复杂系统在LeCaRDv2基准上的近乎全部性能差距。这表明当前的基准可能无法准确衡量真正的法律推理能力,因为相关性往往由指控本身决定,而非深入的案例分析。该研究提出了一个可重用的协议,用于筛查未来基准中类似的构造效度问题。 AI

    充电作为中国法律案件检索的构建效度因素:一项跨基准审计

    Chinese Legal Case Retrieval (LCR) benchmarks grade a reference judgment relevant when its legal characterization matches the query, and strong systems now reach NDCG@10 of 0.85-0.88. Most of the BM25-to-best-trained gap is recoverable with no retrieval model: ranking candidates …
