苹果推出 Glyph 多智能体系统,自动标注企业数据目录列描述与敏感度标签
原标题:Glyph: A Multi-Strategy Agentic System for Column Description and Sensitivity-Ontology Tagging of Enterprise Data Catalogs
AI 摘要
苹果公司研究人员提出 Glyph,一个面向企业数据目录的生产级多智能体系统,用于自动生成列描述并标注敏感度本体标签。系统将列描述生成和列类型标注建模为协作的 LLM 智能体,通过有状态图编排:Descriptor 基于生产该列的管道源代码进行主动检索增强生成,Tagger 并行运行描述、业务线正则和元数据三种策略,并用 RRF 融合排序结果。研究还微调了一个 6 层 MiniLM 元数据编码器,将同标签检索的 NDCG@10 从 0.55 提升至 0.92,并在 340 万列、9.8 万张表的生产目录上验证了可审计、可运维的自动化编目能力。

Glyph: A Multi-Strategy Agentic System for Column Description and Sensitivity-Ontology Tagging of Enterprise Data Catalogs Abstract Enterprise data lakes accumulate tables faster than human stewards can document or classify them, leaving columns with missing descriptions and unassigned governance labels. This documentation debt undermines data discovery, access control, and regulatory compliance. We present Glyph, a production system that frames two coupled problems, column description generatio
