ExtractBench: A Benchmark for Schema-Guided Enterprise Document Extraction
AI 中文解读
企业文档处理迎来新帮手。ExtractBench基准测试首次全面评估AI从复杂文档中提取信息的能力,不仅看准确率,还特别关注AI能否标明信息来源。它测试了370份真实企业文档,涵盖财务、法律等多个领域,发现现有AI普遍存在“长文档健忘症”——读一半就丢信息,而LlamaExtract智能体在保持高准确率的同时,成本仅为同类方案零头。
所谓“模式引导提取”,通俗讲就是让AI照着用户给的表格模板,从合同、报表等文件中自动填出想要的信息,还要标注依据在哪一页哪一行。过去没有统一考试,各说各的好。现在ExtractBench像高考一样,同一套卷子测所有AI,结果一目了然,企业选型不再靠猜。
对企业员工来说,最直观的变化是告别手动录入发票、整理报表的枯燥工作。管理层审核文件时,也能一键查看AI提取的信息是否真实有据,减少“AI幻觉”带来的决策风险。随着这类技术成熟,保险公司理赔、银行信贷审核等流程有望大幅提速,普通人办理业务等待时间可能从几天缩短到几分钟。这项研究让AI从“聊天玩具”真正变成可信赖的办公助手。
Enterprise workflows increasingly rely on agents for \emph{schema-guided extraction}: given a document and a user-defined schema, the agent faithfully follows the schema to produce the correct output with source evidence as grounding metadata. We present ExtractBench, a benchmark for schema-guided extraction and, to our knowledge, the first to score value accuracy, record completeness at scale, grounding, and measured cost together. The evaluation system contains 4,869 pages across 370 enterprise documents, 8 business domains, and 67 document types, with clear tags differentiating their challenge scenarios. The scalable schema and ground-truth curation pipeline combines independent-system agreement for real documents, known values for synthetic lists, and human verification for forms. We report order-insensitive value F1 for value accuracy, plus two grounding metrics for source traceability: word- and page-level F1. Commercial VLMs perform well on short documents but often truncate record lists on long ones, while coding agents retain higher accuracy at much higher cost. LlamaExtract Agentic Plus ranks first on all three metrics, with accuracy comparable to coding agents at a fraction of the cost.
