# LLM-WebToGraph
LLM-WebToGraph is a powerful project that harnesses the capabilities of Langchain and OpenAI's Language Models (LLMs) to scrape data from various sources on the web, transforming it into a structured knowledge graph. This knowledge graph is then populated into a Neo4j Aura Database, providing an efficient way to store, query, and retrieve information using cypher query and LLMs. With the synergy of Langchain, OpenAI LLMs, and Neo4j, this project offers a robust solution for knowledge management and retrieval.
## Architecture
## Overview
The LLM-WebToGraph project combines several key components to achieve its goal:
1. **Langchain:** A language model designed for natural language understanding and generation, powering the core of the project.
2. **OpenAI's Language Models (LLMs):** These models are used to extract and process data from various sources, converting unstructured data into structured knowledge.
3. **Neo4j Aura Database:** The project stores the structured knowledge graph in a Neo4j Aura Database, allowing for efficient storage and retrieval.
4. **FastAPI:** To expose an API for interacting with the project and to check its health status.
5. **Streamlit:** For building a user-friendly interface to query and visualize the knowledge graph.
## Features
- Web scraping from various sources, such as web links and CSV files.
- Data transformation and extraction using OpenAI LLM (gpt-3.5-turbo).
- Population of a structured knowledge graph in Neo4j Aura Database.
- FastAPI-based health check API to monitor the application's status.
- Streamlit web application for querying and visualizing the knowledge graph.
## Getting Started
1. Configuring the data sources
- Update the data files .csv in the data directory.
- Update the links of html in datasource.yml
2. Setup environment variables
- Add credentials in .env file like openAI api key and neo4jDB password or add environment variables.
3. Configure the schema.yml for identities and relationships
- Modify the schema.yml to specify the identities to be recognized.
4. Run the streamlit UI and FASTAPI app.
- build docker and run the image with env file
~~~sh
sudo docker run --env-file .env -p 8501:8501 -p 8000:8000 image_name

## Contributing
Contributions to the LLM-WebToGraph project are welcome! If you'd like to contribute, please follow these guidelines:
- Fork the repository.
- Create a new branch for your feature or bug fix.
- Make your changes and ensure tests pass.
- Submit a pull request.
## Future Scope
In the future, the project can be extended with a microservices architecture, including:
A separate data service responsible for ingesting data from S3.
Utilization of a Selenium bot to scrape the web and download CSV files.
Integration with more data sources for enhanced knowledge graph creation.
