💡 WeKnora - LLM-Powered Document Understanding & Retrieval Framework

📌 Overview

WeKnora is an LLM-powered framework designed for deep document understanding and semantic retrieval, especially for handling complex, heterogeneous documents.

It adopts a modular architecture that combines multimodal preprocessing, semantic vector indexing, intelligent retrieval, and large language model inference. At its core, WeKnora follows the RAG (Retrieval-Augmented Generation) paradigm, enabling high-quality, context-aware answers by combining relevant document chunks with model reasoning.

🏗️ Architecture

WeKnora employs a modern modular design to build a complete document understanding and retrieval pipeline. The system primarily includes document parsing, vector processing, retrieval engine, and large model inference as core modules, with each component being flexibly configurable and extendable.

🎯 Key Features

• 🔍 Precise Understanding: Structured content extraction from PDFs, Word documents, images and more into unified semantic views
• 🧠 Intelligent Reasoning: Leverages LLMs to understand document context and user intent for accurate Q&A and multi-turn conversations
• 🔧 Flexible Extension: All components from parsing and embedding to retrieval and generation are decoupled for easy customization
• ⚡ Efficient Retrieval: Hybrid retrieval strategies combining keywords, vectors, and knowledge graphs
• 🎯 User-Friendly: Intuitive web interface and standardized APIs for zero technical barriers
• 🔒 Secure & Controlled: Support for local deployment and private cloud, ensuring complete data sovereignty

📊 Application Scenarios

🧩 Feature Matrix

🚀 Getting Started

🛠 Prerequisites

Make sure the following tools are installed on your system:

• Docker
• Docker Compose
• Git

📦 Installation

① Clone the repository

# Clone the main repository
git clone https://github.com/Tencent/WeKnora.git
cd WeKnora

② Configure environment variables

# Copy example env file
cp .env.example .env

# Edit .env and set required values
# All variables are documented in the .env.example comments

③ Start the services

# Start all services (Ollama + backend containers)
./scripts/start_all.sh
# Or
make start-all

③ Start the services (backup)

# Start ollama services (Optional)
ollama serve > /dev/null 2>&1 &

# Start the service
docker compose up -d

④ Stop the services

./scripts/start_all.sh --stop
# Or
make stop-all

🌐 Access Services

Once started, services will be available at:

• Web UI: http://localhost
• Backend API: http://localhost:8080
• Jaeger Tracing: http://localhost:16686

🔌 Using WeChat Dialog Open Platform

WeKnora serves as the core technology framework for the WeChat Dialog Open Platform, providing a more convenient usage approach:

• Zero-code Deployment: Simply upload knowledge to quickly deploy intelligent Q&A services within the WeChat ecosystem, achieving an “ask and answer” experience
• Efficient Question Management: Support for categorized management of high-frequency questions, with rich data tools to ensure accurate, reliable, and easily maintainable answers
• WeChat Ecosystem Integration: Through the WeChat Dialog Open Platform, WeKnora’s intelligent Q&A capabilities can be seamlessly integrated into WeChat Official Accounts, Mini Programs, and other WeChat scenarios, enhancing user interaction experiences

🔗 Access WeKnora via MCP Server

1️⃣ Clone the repository

git clone https://github.com/Tencent/WeKnora

2️⃣ Configure MCP Server

Configure the MCP client to connect to the server:

{
  "mcpServers": {
    "weknora": {
      "args": [
        "path/to/WeKnora/mcp-server/run_server.py"
      ],
      "command": "python",
      "env":{
        "WEKNORA_API_KEY":"Enter your WeKnora instance, open developer tools, check the request header x-api-key starting with sk",
        "WEKNORA_BASE_URL":"http(s)://your-weknora-address/api/v1"
      }
    }
  }
}

Run directly using stdio command:

pip install weknora-mcp-server
python -m weknora-mcp-server

🔧 Initialization Configuration Guide

To help users quickly configure various models and reduce trial-and-error costs, we’ve improved the original configuration file initialization method by adding a Web UI interface for model configuration. Before using, please ensure the code is updated to the latest version. The specific steps are as follows: If this is your first time using this project, you can skip steps ①② and go directly to steps ③④.

① Stop the services

./scripts/start_all.sh --stop

② Clear existing data tables (recommended when no important data exists)

make clean-db

③ Compile and start services

./scripts/start_all.sh

④ Access Web UI

http://localhost

On first access, it will automatically redirect to the initialization configuration page. After configuration is complete, it will automatically redirect to the knowledge base page. Please follow the page instructions to complete model configuration.

📱 Interface Showcase

Web UI Interface

Knowledge Upload	Q&A Entry
Rich Text & Image Responses

Knowledge Base Management: Support for dragging and dropping various documents, automatically identifying document structures and extracting core knowledge to establish indexes. The system clearly displays processing progress and document status, achieving efficient knowledge base management.

Document Knowledge Graph

WeKnora supports transforming documents into knowledge graphs, displaying the relationships between different sections of the documents. Once the knowledge graph feature is enabled, the system analyzes and constructs an internal semantic association network that not only helps users understand document content but also provides structured support for indexing and retrieval, enhancing the relevance and breadth of search results.
