⚠️ This Repo is Work in Progress ⚠️

This project is designed to implement an agent capable of interacting with a graph database like Neo4j through a semantic layer using OpenAI function calling. The semantic layer equips the agent with a suite of robust tools, allowing it to interact with the graph database based on the user's intent. Read more in the blog post.

To start the project, run the following command:

docker-compose up

Open http://localhost:8501 in your browser to interact with the agent.

Tools

The agent utilizes several tools to interact with the Neo4j graph database effectively:

1. Information tool:
   • Retrieves data about movies or individuals, ensuring the agent has access to the latest and most relevant information.
2. Recommendation Tool:
   • Provides movie recommendations based upon user preferences and input.
3. Plot Tool:
   • Finds movies based by their description using vector similarity search.
4. Aggregation Tool:
   • Calculates statistics by generating Cypher statements.

Environment Setup

You need to define the following environment variables in the .env file.

OPENAI_API_KEY=<YOUR_OPENAI_API_KEY>
NEO4J_URI=<YOUR_NEO4J_URI>
NEO4J_USERNAME=<YOUR_NEO4J_USERNAME>
NEO4J_PASSWORD=<YOUR_NEO4J_PASSWORD>

Docker containers

This project contains the following services wrapped as docker containers

1. Neo4j:
   • Neo4j, a graph database, is used to store the information about actors, movies, and their ratings.
2. API:
   • Uses LangChain's neo4j-semantic-layer template to implement the OpenAI LLM and function calling capabilities.
3. UI:
   • Simple streamlit chat user interface. Available on localhost:8501.

Populating with data
