💡 What is RAGFlow?

RAGFlow is a knowledge management platform built on custom-build document understanding engine and LLM, with reasoned and well-founded answers to your question. Clone this repository, you can deploy your own knowledge management platform to empower your business with AI.

🌟 Key Features

• 🍭Custom-build document understanding engine. Our deep learning engine is made according to the needs of analyzing and searching various type of documents in different domain.
  • For documents from different domain for different purpose, the engine applies different analyzing and search strategy.
  • Easily intervene and manipulate the data proccessing procedure when things goes beyond expectation.
  • Multi-media document understanding is supported using OCR and multi-modal LLM.
• 🍭State-of-the-art table structure and layout recognition. Precisely extract and understand the document including table content. See README.
  • For PDF files, layout and table structures including row, column and span of them are recognized.
  • Put the table accrossing the pages together.
  • Reconstruct the table structure components into html table.
    
• Querying database dumped data are supported. After uploading tables from any database, you can search any data records just by asking.
  • You can now query a database using natural language instead of using SQL.
  • The record number uploaded is not limited.
• Reasoned and well-founded answers. The cited document part in LLM’s answer is provided and pointed out in the original document.
  • The answers are based on retrieved result for which we apply vector-keyword hybrids search and re-rank.
  • The part of document cited in the answer is presented in the most expressive way.
  • For PDF file, the cited parts in document can be located in the original PDF.
    

🔎 System Architecture

🎬 Get Started

📝 Prerequisites

• CPU >= 2 cores
• RAM >= 8 GB
• Docker: If you have not installed Docker on your local machine (Windows, Mac, or Linux), see Install Docker Engine.

Start up the server

1. Ensure vm.max_map_count > 65535:

To check the value of vm.max_map_count:

   > $ sysctl vm.max_map_count
   > ```
   >
   > Reset `vm.max_map_count` to a value greater than 65535 if it is not.
   >
   > ```bash
   > # In this case, we set it to 262144:
   > $ sudo sysctl -w vm.max_map_count=262144
   > ```
   >
   > This change will be reset after a system reboot. To ensure your change remains permanent, add or update the `vm.max_map_count` value in **/etc/sysctl.conf** accordingly:
   >
   > ```bash
   > vm.max_map_count=262144
   > ```

2. Clone the repo:

   ```bash
   $ git clone https://github.com/infiniflow/ragflow.git

1. Build the pre-built Docker images and start up the server:

   $ cd ragflow/docker
   $ docker compose up -d

The core image is about 15 GB in size and may take a while to load.

1. Check the server status after pulling all images and having Docker up and running: bash $ docker logs -f ragflow-server The following output confirms a successful launch of the system:

    ____                 ______ __               
   / __ \ ____ _ ____ _ / ____// /____  _      __
  / /_/ // __ `// __ `// /_   / // __ \| | /| / /
 / _, _// /_/ // /_/ // __/  / // /_/ /| |/ |/ /

              /____/                             

 * Running on all addresses (0.0.0.0)
 * Running on http://127.0.0.1:9380
 * Running on http://172.22.0.5:9380
INFO:werkzeug:Press CTRL+C to quit

1. In your web browser, enter the IP address of your server as prompted. The show is on!

🔧 Configurations

The default serving port is 80, if you want to change that, refer to the docker-compose.yml and change the left part of 80:80, say 66:80.

If you need to change the default setting of the system when you deploy it. There several ways to configure it. Please refer to this README to manually update the configuration. Updates to system configurations require a system reboot to take effect docker-compose up -d again.

If you want to change the basic setups, like port, password .etc., please refer to .env before starting up the system.

If you change anything in .env, please check service_conf.yaml which is a configuration of the back-end service and should be consistent with .env.

🛠️ Build from source

To build the Docker images from source:

$ git clone https://github.com/infiniflow/ragflow.git
$ cd ragflow/
$ docker build -t infiniflow/ragflow:v1.0 .
$ cd ragflow/docker
$ docker compose up -d
