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

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
