# Source-Grounding
## Definition
Source-Grounding 是一种 AI 回答质量控制机制,严格将 AI 知识库限制为用户上传的文档,确保每个回答都直接溯源至原文,拒绝生成不可验证的推测性内容。
## Description
NotebookLM 的核心机制。与传统 RAGRetrieval-Augmented Generation不同Source-Grounding 不依赖外部知识库而是以用户提供的文档作为唯一事实来源从根本上消除幻觉Hallucination问题。
## Key Properties
1. **知识边界清晰**AI 仅能访问上传文档,无法访问外部信息
2. **引文强制**:每个回答必须附带原文引文,可点击跳转验证
3. **准确性优先**:以牺牲通用性换取可信度,适用于法律、医学、项目文档等高精度场景
