HugeGraph-AI

hugegraph-ai integrates HugeGraph with artificial intelligence capabilities, providing comprehensive support for developers to build AI-powered graph applications.

✨ Key Features

• GraphRAG: Build intelligent question-answering systems with graph-enhanced retrieval
• Knowledge Graph Construction: Automated graph building from text using LLMs
• Graph ML: Integration with 20+ graph learning algorithms (GCN, GAT, GraphSAGE, etc.)
• Python Client: Easy-to-use Python interface for HugeGraph operations
• AI Agents: Intelligent graph analysis and reasoning capabilities

🚀 Quick Start

[!NOTE] For a complete deployment guide and detailed examples, please refer to hugegraph-llm/README.md

Prerequisites

• Python 3.9+ (3.10+ recommended for hugegraph-llm)
• uv (recommended package manager)
• HugeGraph Server 1.3+ (1.5+ recommended)
• Docker (optional, for containerized deployment)

Option 1: Docker Deployment (Recommended)

# Clone the repository git clone https://github.com/apache/incubator-hugegraph-ai.git cd incubator-hugegraph-ai  # Set up environment and start services cp docker/env.template docker/.env # Edit docker/.env to set your PROJECT_PATH cd docker docker-compose -f docker-compose-network.yml up -d  # Access services: # - HugeGraph Server: http://localhost:8080 # - RAG Service: http://localhost:8001 

Option 2: Source Installation

# 1. Start HugeGraph Server docker run -itd --name=server -p 8080:8080 hugegraph/hugegraph  # 2. Clone and set up the project git clone https://github.com/apache/incubator-hugegraph-ai.git cd incubator-hugegraph-ai/hugegraph-llm  # 3. Install dependencies uv venv && source .venv/bin/activate uv pip install -e .  # 4. Start the demo python -m hugegraph_llm.demo.rag_demo.app # Visit http://127.0.0.1:8001 

Basic Usage Examples

GraphRAG - Question Answering

from hugegraph_llm.operators.graph_rag_task import RAGPipeline  # Initialize RAG pipeline graph_rag = RAGPipeline()  # Ask questions about your graph result = (graph_rag  .extract_keywords(text="Tell me about Al Pacino.")  .keywords_to_vid()  .query_graphdb(max_deep=2, max_graph_items=30)  .synthesize_answer()  .run()) 

Knowledge Graph Construction

from hugegraph_llm.models.llms.init_llm import LLMs from hugegraph_llm.operators.kg_construction_task import KgBuilder  # Build KG from text TEXT = "Your text content here..." builder = KgBuilder(LLMs().get_chat_llm())  (builder  .import_schema(from_hugegraph="hugegraph")  .chunk_split(TEXT)  .extract_info(extract_type="property_graph")  .commit_to_hugegraph()  .run()) 

Graph Machine Learning

from pyhugegraph.client import PyHugeClient # Connect to HugeGraph and run ML algorithms # See hugegraph-ml documentation for detailed examples
