📄️ Configure knowledge base
Knowledge base, hallucination-free chat, and file management are the three pillars of RAGFlow. RAGFlow's AI chats are based on knowledge bases. Each of RAGFlow's knowledge bases serves as a knowledge source, parsing files uploaded from your local machine and file references generated in File Management into the real 'knowledge' for future AI chats. This guide demonstrates some basic usages of the knowledge base feature, covering the following topics:
📄️ Set metadata
Add metadata to an uploaded file
📄️ Select PDF parser
Select a visual model for parsing your PDFs.
📄️ Set page rank
Create a step-retrieval strategy using page rank.
📄️ Auto-keyword Auto-question
Use a chat model to generate keywords or questions from each chunk in the knowledge base.
📄️ Enable Excel2HTML
Convert complex Excel spreadsheets into HTML tables.
📄️ Use tag set
Use a tag set to auto-tag chunks in your datasets.
📄️ Enable RAPTOR
A recursive abstractive method used in long-context knowledge retrieval and summarization, balancing broad semantic understanding with fine details.
📄️ Construct knowledge graph
Generate a knowledge graph for your knowledge base.
📄️ Run retrieval test
Conduct a retrieval test on your knowledge base to check whether the intended chunks can be retrieved.
