PageIndex:为推理型RAG构建结构化文档索引的开源解决方案
AI Insight
PageIndex is an open-source document indexing system designed for reasoning-based RAG, which structures long documents into hierarchical trees rather than fixed chunks, enabling LLMs to perform targeted traversal and multi-step reasoning for more accurate retrieval in professional domains like finance, law, and technical documentation. PageIndex为推理型RAG设计的开源文档索引系统,通过将长文档构建为层次化树形结构而非固定分块,使大模型能够进行定向遍历和多步推理,在金融、法律、技术文档等专业领域实现更精准的检索。AI大模型2026/1/27
