GraphRAG4OpenWebUI: Enhancing Open WebUI with Advanced Information Retrieval
GraphRAG4OpenWebUI is a cutting-edge project that brings Microsoft's GraphRAG (Graph-based Retrieval-Augmented Generation) technology to Open WebUI, a popular open-source web user interface framework. This project sets out to provide an advanced information retrieval system, making it simpler and more efficient for users to access information from various sources.
Project Overview
The primary aim of GraphRAG4OpenWebUI is to empower Open WebUI with GraphRAG's robust features. Through this integration, users are treated to a seamless and comprehensive search experience, utilizing three core retrieval methods designed to ensure the search results are accurate and relevant.
Key Retrieval Methods
-
Local Search
- This method focuses on utilizing GraphRAG for efficient searches within local knowledge bases, making it ideal for quick access to structured information.
- By using graph structures, it enhances the precision and relevance of the retrieved data.
-
Global Search
- Operating on a broader spectrum, this method extends its reach beyond local data to find richer information that's not confined to a pre-defined scope.
- It leverages GraphRAG's ability to understand global contexts, offering more comprehensive search results for complex queries.
-
Tavily Search
- Integrating the Tavily search API, this method broadens the scope to include external internet searches, thereby extending the sources of information.
- It is perfect for searches that require up-to-date or extensive online information.
-
Full Model Search
- This method combines the strengths of the Local, Global, and Tavily Search features, providing the most all-encompassing results to fulfill complex information needs.
- It intelligently integrates and ranks information from diverse sources.
Support for Local Models and Embeddings
The project also supports the use of local language models (LLMs) and embedding models, which enhances its flexibility while bolstering data privacy. Users have the option to use open-source LLMs through platforms like Ollama or LM Studio, as well as locally hosted embedding models. This ensures operations can be conducted without reliance on external services, reducing cost and improving security.
Installation Guide
To get started with GraphRAG4OpenWebUI, ensure you have Python 3.8 or above, and follow these steps:
- Clone the repository from GitHub and navigate into the directory.
- Set up a Python virtual environment and activate it.
- Install all necessary dependencies using
pip.
It's crucial to configure certain environment variables related to API keys and model settings, which can be defined in a .env file or directly in the terminal.
Usage Instructions
Once installed, start the server by running the specified Python script, which will host the service locally. The API offers various endpoints for performing searches and retrieving model information, which can then be integrated with Open WebUI to enhance its capabilities.
Available Models
- Local Search Model: Efficient for localized information retrieval.
- Global Search Model: Broader scope for comprehensive data.
- Tavily Search Model: Excellent for expansive internet searches.
- Full Model: A complete package offering a combination of all strategies.
