RAG系统需要更好的文档摄取，而不仅仅是更好的LLM

本文认为，检索增强生成（RAG）系统中的许多失败源于糟糕的文档摄取，而不是语言模型本身的问题。它提出了一种“结构化分块”方法，该方法优先解析文档的内在结构，例如章节、表格和标题，然后再根据令牌限制分割文本。该方法旨在创建更连贯、更具上下文相关性的块，提高检索质量，特别是对于视觉复杂的文档，在这些文档中，基于图像的检索可能比文本提取更有效。 AI

影响改进文档摄取管道可以显著提高RAG系统的性能，并减少对更强大LLM的依赖。

Signal score: 0 / 100; Composite score across the factors below. Higher = stronger signal that this story matters right now.
Newsworthiness bucket: Commentary; 文章提供了关于改进RAG系统的观点和技术分析，而不是发布新产品或研究。
Source corroboration: Single-source cluster; Only one publisher covered this so far. Single-source stories can still rank when the publisher is high-authority, but they lack cross-source corroboration.
Topics: infra, product; Editorial topic classification. Feeds into how the story surfaces on /topic/<slug> hub pages and into the per-entity coverage mix.

Stop Flattening Your PDFs: Document Intelligence and Structural Chunking for RAG and Agents

<p>Many RAG failures that look like model problems are ingestion problems. If a parser flattens a PDF into a stream of characters and a splitter cuts that stream every 1,000 characters, the best embedding model and the best LLM are working with debris.</p> <p>The authors of ColPa…
