Instead of feeding an LLM a full blueprint of every possible output field, SchemaRAG uses schema metadata and few-shot examples to identify which parts of the schema are actually relevant to a given input. The team tested it on healthcare and e-commerce datasets — two domains notorious for sprawling, deeply nested data structures. Results showed up to an 8.8% improvement in micro-F1 scores, a 47% drop in latency, and a 48% reduction in token costs.\n\nThe cost and latency numbers matter more than the accuracy bump. Anyone running structured extraction at scale knows that ballooning prompts are a silent tax — and the \"lost-in-the-middle\" problem, where models ignore content buried deep in a long context, compounds the damage. SchemaRAG attacks both problems at once by keeping prompts lean without requiring a smaller or faster model.\n\nThe approach is a targeted answer to a pain point that grows more acute as enterprises push LLMs into complex data pipelines. RAG is already a standard tool for document retrieval; applying the same logic to schema retrieval is a logical extension — one that, on this evidence, pays off without the need for model fine-tuning or architectural overhaul.","[\"ai\",\"llm\",\"rag\",\"data-extraction\"]","2026-07-02T04:00:00.000Z","2026-07-02T04:44:11.545Z","2026-07-02T04:44:14.415Z","published",null,[],"ai",[24,26,27,28],"llm","rag","data-extraction",[30],{"name":31,"url":32},"arXiv cs.AI","https:\u002F\u002Farxiv.org\u002Fabs\u002F2607.00008",0,{"sections":35},[36,40,45,50,55,60,65,70,75,80,85,89,94,99],{"name":37,"slug":24,"count":38,"latest_published_at":39},"AI",2590,"2026-07-16T04:00:00.000Z",{"name":41,"slug":42,"count":43,"latest_published_at":44},"Security","security",294,"2026-07-15T19:59:48.000Z",{"name":46,"slug":47,"count":48,"latest_published_at":49},"Deals","deals",179,"2026-06-29T20:02:07.000Z",{"name":51,"slug":52,"count":53,"latest_published_at":54},"Policy","policy",158,"2026-07-16T00:02:48.000Z",{"name":56,"slug":57,"count":58,"latest_published_at":59},"Hardware","hardware",122,"2026-07-14T19:46:26.000Z",{"name":61,"slug":62,"count":63,"latest_published_at":64},"Consumer Tech","consumer-tech",93,"2026-07-13T13:20:48.000Z",{"name":66,"slug":67,"count":68,"latest_published_at":69},"Software","software",70,"2026-07-13T19:52:25.000Z",{"name":71,"slug":72,"count":73,"latest_published_at":74},"Science","science",66,"2026-07-10T10:29:37.000Z",{"name":76,"slug":77,"count":78,"latest_published_at":79},"Dev Tools","dev-tools",59,"2026-07-07T04:00:00.000Z",{"name":81,"slug":82,"count":83,"latest_published_at":84},"Gaming","gaming",41,"2026-07-09T04:00:00.000Z",{"name":86,"slug":87,"count":83,"latest_published_at":88},"Startups","startups","2026-06-29T20:55:50.000Z",{"name":90,"slug":91,"count":92,"latest_published_at":93},"General","general",29,"2026-07-10T22:28:58.000Z",{"name":95,"slug":96,"count":97,"latest_published_at":98},"Reviews","reviews",20,"2026-06-24T12:00:01.000Z",{"name":100,"slug":101,"count":102,"latest_published_at":103},"How-To","how-to",6,"2026-06-16T09:00:00.000Z"]
