LlamaIndex 用 ExtractBench 解析文档抽取的置信度过滤实践
做文档抽取的可以看看，LlamaIndex 用 ExtractBench 实测了置信度过滤怎么用，97% 精确率下 LlamaParse 召回 66.48%，教你算该放多少单自动跑。
LlamaIndex 发布了一篇关于文档抽取中置信度分数用法的文章，核心观点是分数的价值在于指导自动化决策。文章覆盖置信度阈值、精确率与召回率、分数覆盖率、分数粒度和人工审核量五个要点。
基于 ExtractBench 的对比显示，在 97% 精确率目标下，LlamaParse Agentic Plus 过滤后召回率达到 66.48%。
文章强调应把置信度用于控制生产环境的自动化比例和人工审核量。
confidence scores only matter if they help you decide what to automate. for document extraction, that usually means knowing how much work you can safely accept at a given precision target. in our latest post, we look at confidence scoring through that lens, including: ✅️ confidence cutoffs ✅️ precision vs. recall ✅️ score coverage ✅️ score granularity ✅️ human review volume using ExtractBench, we compare how different extraction systems perform after confidence filtering. at a 97% precision target, LlamaParse Agentic Plus reached 66.48% recall on expected fields after filtering. the useful part of a confidence score isn’t the number itself. it’s whether you can use it to control automation and review in production. 👉️ read the full post: llamaindex.ai/blog/what-make… f
