break-word !important;">上述 LlamaIndex 的演示只是提供了评估的思路和方向，不能替代在目标平台上的实际验证。各位可以利用上述LlamaIndex 演示中的原理，去解读 Ragflow/Dify等框架提供的分块选项。 <p label="Converted by KNB Formatter from Jason Ng https://knb.im/mp" style="margin: 20px;max-width: 100%;min-height: 1em;white-space: pre-wrap;color: rgb(43, 43, 43);text-align: justify;line-height: 1.5;box-sizing: border-box !important;word-wrap: break-word !important;">以RAGFlow为例，相关分块选项和上述的五种分块策略很难一一映射，结合官方的python api解读参考如下： <p style="margin: 20px;max-width: 100%;min-height: 1em;white-space: pre-wrap;color: rgb(43, 43, 43);text-align: justify;line-height: 1.5;box-sizing: border-box !important;overflow-wrap: break-word !important;"><span leaf="" style="min-height: 1em;text-align: justify;max-width: 100%;line-height:

pre-wrap;border-width: 0.25em 0px;display: inline;font-weight: normal;padding: 2px 4px;box-sizing: border-box !important;overflow-wrap: break-word !important;">固定大小分块: Ragflow 的 "naive" 方法最接近这个概念，尤其是当配置了 chunk_token_num 时。它可能也结合了 delimiter 进行分割。 <p style="margin: 20px;max-width: 100%;min-height: 1em;white-space: pre-wrap;color: rgb(43, 43, 43);text-align: justify;line-height:

inline;font-weight: normal;padding: 2px 4px;box-sizing: border-box !important;overflow-wrap: break-word !important;">语义分块: API 文档中没有直接命名为 "semantic" 的选项。然而，某些高级方法（像 "qa"、"knowledge_graph" 某种程度上）可能隐含了语义理解。但 API 没有提供一个像 LangChain 那样明确的 Semantic Splitter 选项。 <p style="margin: 20px;max-width: 100%;min-height: 1em;white-space: pre-wrap;color: rgb(43, 43, 43);text-align: justify;line-height:

inline;font-weight: normal;padding: 2px 4px;box-sizing: border-box !important;overflow-wrap: break-word !important;">递归分块: 像 "book" 或 "paper" 这样的方法内部猜测是采用了递归或基于结构的分块逻辑，会先尝试按大纲（章节、标题）分割，如果块太大再按段落或句子递归分割。但API 文档没有明确说明其内部递归逻辑。 <p style="margin: 20px;max-width: 100%;min-height: 1em;white-space: pre-wrap;color: rgb(43, 43, 43);text-align:

"presentation", "table" 这些方法明显是针对特定文档结构的，它们会优先利用文档的固有结构（标题、章节、表格结构、幻灯片等）来定义块边界。 <p style="margin: 20px;max-width: 100%;min-height: 1em;white-space: pre-wrap;color: rgb(43, 43, 43);text-align:

<p style="margin: 20px;max-width: 100%;min-height: 1em;white-space: pre-wrap;color: rgb(43, 43, 43);text-align: justify;line-height: 1.5;box-sizing: border-box !important;overflow-wrap: break-word

!important;overflow-wrap: break-word !important;">这里需要特别说明的是，在RAGFlow中创建知识库环节，自动关键词/问题提取不是LLM-based Chunking，而是分块后的 LLM 增强。但RAPTOR(递归摘要树，多粒度检索) 策略涉及对初始块进行聚类，并使用 LLM 对聚类进行摘要，生成新的、更高层次的“摘要块”。这个策略可以被认为是“基于 LLM 的分块”的一种高级形式或应用。虽然它可能建立在初始分块之上，但它确实利用 LLM 生成了新的、语义层级更高的块（摘要），这些新块是文档内容的一种 LLM 驱动的重新组织和分割。它不仅仅是分析现有块，而是创造了新的块边界和内容。<span leaf="" style="max-width:

参数暴露的分块方法，或者你想彻底改变其检索逻辑）超出了 Ragflow 提供的 API 和配置选项的范畴，理论上唯一的途径就是修改 Ragflow 的源代码。 <p label="Converted by KNB Formatter from Jason Ng https://knb.im/mp" style="margin: 20px;max-width: 100%;min-height:

这样的框架通常有复杂的内部结构和依赖关系，理解并安全地修改其核心代码需要投入大量时间和精力。而且鉴于 RAGFlow 在常态化更新中，创建一个 Ragflow 的“定制分支”意味着官方的更新、补丁或新功能无法直接合并，需要自己手动同步或重新应用你的修改，维护成本很高。 <p label="Converted by KNB Formatter from Jason Ng

LlamaIndex（或 LangChain 等类似库）来构建自己的企业级 RAG 应用，而不是使用封装好的平台。 <p label="Converted by KNB Formatter from Jason Ng https://knb.im/mp" style="margin: 20px;max-width: 100%;min-height: 1em;white-space: pre-wrap;color: rgb(43, 43, 43);text-align: justify;line-height: 1.5;box-sizing: border-box !important;word-wrap: break-word !important;">除了可以更好的与现有技术栈集成外，企业可以完全掌控 RAG 流程的每一个环节，选择最适合需求的模型（嵌入、LLM、重排）、向量数据库、索引策略、检索逻辑等，并进行深度定制和优化。 <p label="Converted by KNB Formatter from Jason Ng https://knb.im/mp" style="margin: 20px;max-width: 100%;min-height: 1em;white-space: pre-wrap;color: rgb(43, 43, 43);text-align: justify;line-height: 1.5;box-sizing: border-box !important;word-wrap: break-word !important;">但问题也随着而来，这需要开发或集成几乎所有“外围”组件，包括 UI、API、数据库、部署运维在内的所有周边系统。毕竟LlamaIndex 虽然提供了 RAG 的核心“引擎”和“管道”，但它本身不是一个可以直接部署给最终用户的完整应用。 <p label="Converted by KNB Formatter from Jason Ng https://knb.im/mp" style="margin: 20px;max-width:

!important;">一般的建议是，针对企业级知识库项目落地，如果需求与某个成熟框架的功能高度匹配，且对定制化要求不高，或者时间紧迫需要快速验证，那么选择 Ragflow/Dify 显然更高效。但如果企业对 RAG 的性能、逻辑有深度定制的需求，希望完全掌控技术栈，拥有较强的内部研发能力，或者需要将 RAG 深度嵌入现有复杂系统，那么基于 LlamaIndex 自建通常是更长远、更灵活的选择，尽管前期投入更大。
