Movie QA System with Graph Database

Author: Heesun Moon
Peer Review: Jongcheol Kim, Taylor(Jihyun Kim)
Proofread : Juni Lee
This is a part of LangChain Open Tutorial

Overview

This tutorial covers the implementation of a movie QA system using a graph database with Neo4j .

It explains the process of storing data in a graph database and implementing a text2Cypher conversion feature using LLMs. This allows natural language queries to be converted into Cypher queries, and the answers retrieved from the database are returned in natural language as well.

⚠️Security Note
Building Q&A systems with graph databases involves executing model-generated queries, which carries inherent risks. To minimize these risks, restrict database permissions to the narrowest scope required for your chain or agent. While this reduces vulnerabilities, it does not eliminate them entirely. For more security best practices, see the LangChain security documentation.

Connect to Neo4j Graph Database

First, install the Neo4j graph database. This tutorial is based on Neo4j Desktop .

installation

[Note] You can also set up a free, cloud-based Neo4j instance using Neo4j Sandbox, an online platform for working with graph databases.

After installing, open Neo4j Desktop. A default Example Project should be available. We'll use this project for this tutorial.

Activate Database

Click the Start to activate the Movie DBMS .

Setup APOC Plugin

Open the Movie DBMS project.
Go to the Plugins section.
Select APOC and click Install and Restart .

To allow external network connections, you need to update the neo4j.conf file.

Open the terminal in Neo4j Desktop .

Navigate to the configuration file directory and edit neo4j.conf .

# Change Directory
cd conf
# Windows
notepad neo4j.conf
# Linux/Mac
nano neo4j.conf

Add or modify the following line in the neo4j.conf file:

server.default_listen_address=0.0.0.0

Define Neo4j Credentials

Next, you need to define your Neo4j credentials. If you haven't done this in the previous steps, you can define them using the os package.

[Note] This is not necessary if you've already set the required Neo4j credentials in previous steps.

The default user account information:
Default username: neo4j
Default password: neo4j
You are required to change the password upon your first login.

import os

os.environ["NEO4J_URI"] = "bolt://localhost:7687"
os.environ["NEO4J_USERNAME"] = "neo4j"
os.environ["NEO4J_PASSWORD"] = "neo4j"

The following example demonstrates how to connect to a Neo4j database and populate it with sample data about movies and actors.

from langchain_neo4j import Neo4jGraph

graph = Neo4jGraph()

# Step 1: Delete all existing data
delete_query = """
MATCH (n)
DETACH DELETE n
"""
graph.query(delete_query)

# Step 2: Load new movie dataset
movies_query = """
LOAD CSV WITH HEADERS FROM 
'https://raw.githubusercontent.com/tomasonjo/blog-datasets/main/movies/movies_small.csv'
AS row
MERGE (m:Movie {id:row.movieId})
SET m.released = date(row.released),
    m.title = row.title,
    m.imdbRating = toFloat(row.imdbRating)
FOREACH (director in split(row.director, '|') | 
    MERGE (p:Person {name:trim(director)})
    MERGE (p)-[:DIRECTED]->(m))
FOREACH (actor in split(row.actors, '|') | 
    MERGE (p:Person {name:trim(actor)})
    MERGE (p)-[:ACTED_IN]->(m))
FOREACH (genre in split(row.genres, '|') | 
    MERGE (g:Genre {name:trim(genre)})
    MERGE (m)-[:IN_GENRE]->(g))
"""

graph.query(movies_query)

Graph Schema

LLMs use graph schema information to convert natural language questions into Cypher queries. The converted query is executed in the database, and the execution results are provied to the LLM for question answering.

# Update schema
graph.refresh_schema()
# Print the current schema
print(graph.schema)

Node properties:
    Movie {title: STRING, released: DATE, id: STRING, imdbRating: FLOAT}
    Person {name: STRING}
    Genre {name: STRING}
    Relationship properties:
    
    The relationships:
    (:Movie)-[:IN_GENRE]->(:Genre)
    (:Person)-[:DIRECTED]->(:Movie)
    (:Person)-[:ACTED_IN]->(:Movie)

Now, let's check the enhanced schema information. Enhanced Schema Information provides a detailed overview of the graph structure, including node labels, relationship types, and property details such as data types and value ranges. This is particularly useful for generating more complex queries and leveraging LLMs for advanced use cases.

To enable Enhanced Schema, set the parameter enhanced_schema=True when initializing the graph object.

Key Features:

Property Types : Shows the data type (e.g., STRING, INTEGER, FLOAT) of each property.
Value Ranges : Displays minimum and maximum values for numeric fields.
Examples : Provides sample values for quick reference.
Relationships : Lists connection types between nodes and their property details.

enhanced_graph = Neo4jGraph(enhanced_schema=True)
print(enhanced_graph.schema)

Received notification from DBMS server: {severity: WARNING} {code: Neo.ClientNotification.Statement.FeatureDeprecationWarning} {category: DEPRECATION} {title: This feature is deprecated and will be removed in future versions.} {description: The procedure has a deprecated field. ('config' used by 'apoc.meta.graphSample' is deprecated.)} {position: line: 1, column: 1, offset: 0} for query: "CALL apoc.meta.graphSample() YIELD nodes, relationships RETURN nodes, [rel in relationships | {name:apoc.any.property(rel, 'type'), count: apoc.any.property(rel, 'count')}] AS relationships"

Node properties:
- **Movie**
  - `title`: STRING Example: "Toy Story"
  - `released`: DATE Min: 1964-12-16, Max: 1996-09-15
  - `id`: STRING Example: "1"
  - `imdbRating`: FLOAT Min: 2.4, Max: 9.3
- **Person**
  - `name`: STRING Example: "John Lasseter"
- **Genre**
  - `name`: STRING Example: "Adventure"
Relationship properties:

The relationships:
(:Movie)-[:IN_GENRE]->(:Genre)
(:Person)-[:DIRECTED]->(:Movie)
(:Person)-[:ACTED_IN]->(:Movie)

GraphQACypherChain

The GraphCypherQAChain simplifies the process of querying graph databases using natural language by integrating LLMs and Neo4j. It enables users to interact with graph data through natural language queries by converting them into Cypher queries, which are executed against a Neo4j database.

Key Features:

Text-to-Cypher Conversion : Automatically translates natural language questions into Cypher queries.
Query Execution : Executes the generated queries against a Neo4j graph database.
Natural Language Answers : Processes and formats query results into human-readable answers.
LLM Integration : Leverages Large Language Models (LLMs), like OpenAI’s GPT, for query generation and result interpretation.
Enhanced Schema Support : Can work with enhanced schema information for more accurate query generation.

Using a New Dataset

Now that we’re incorporating more diverse user and movie information, we can expand our perspective on movie recommendations. We'll utilize Kaggle's The Movies Dataset to run simple queries for recommendations.

To begin, we'll set up a new local DBMS to import and use this external dataset.

Create a New Local DBMS

Refer to the images below to create a new Local DBMS named Kaggle Movie DBMS :

Next, connect to the Neo4j Graph Database as previously explained.

Connect to Neo4j Graph Database

Define Neo4j Credentials

Next, you need to define your Neo4j credentials. If you haven't done this in the previous steps, you can define them using the os package.

To import the dataset, you need to set the import path environment variable. In the image below, you can check the import path by clicking the import button. This path is where you will download and store the dataset.

[Note] This is not necessary if you've already set the required Neo4j credentials in previous steps.

from langchain_neo4j import Neo4jGraph
import os

os.environ["NEO4J_URI"] = "bolt://localhost:7687"
os.environ["NEO4J_USERNAME"] = "neo4j"
os.environ["NEO4J_PASSWORD"] = "neo4j"
os.environ["IMPORT_DIR"] = "YOUR_IMPORT_DIR"

graph = Neo4jGraph()

Download a New Dataset: Kaggle's The Movies Dataset

Download the Kaggle dataset and move it to the import path .

import kagglehub
import shutil

# Download the Kaggle dataset
path = kagglehub.dataset_download("rounakbanik/the-movies-dataset")

print("Path to dataset files:", path)
print("*" * 30)

# Target path where the dataset files will be moved
target_path = os.environ.get("IMPORT_DIR")
os.makedirs(target_path, exist_ok=True)

# Move dataset files to the target path
for file_name in os.listdir(path):
    shutil.move(os.path.join(path, file_name), os.path.join(target_path, file_name))

print("Files moved to:", target_path)
