💡 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.

   # 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:

   vm.max_map_count=262144
   

2. Clone the repo:

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

3. 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.

4. Check the server status after pulling all images and having Docker up and running:

   $ 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
   

5. In your web browser, enter the IP address of your server as prompted.

   The show is on!

🔧 Configurations

When it comes to system configurations, you will need to manage the following files:

• .env: Keeps the fundamental setups for the system, such as SVR_HTTP_PORT, MYSQL_PASSWORD, and MINIO_PASSWORD.
• service_conf.yaml: Configures the back-end services.
• docker-compose.yml: The system relies on docker-compose.yml to start up.

You must ensure that changes in .env are in line with what are in the service_conf.yaml file.

The ./docker/README file provides a detailed description of the environment settings and service configurations, and it is IMPORTANT to ensure that all environment settings listed in the ./docker/README file should be aligned with the corresponding settings in the service_conf.yaml file.

To change the default serving port (80), go to docker-compose.yml and change 80:80 to <YOUR_SERVING_PORT>:80.

Updates to all system configurations require a system reboot to take effect:

$ docker-compose up -d

🛠️ 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
