This project is a conversational AI system that allows users to ask questions about STAC Collections using natural language. It integrates with Neo4j for data retrieval and OpenAI's GPT models for generating responses. The system is designed to make geospatial data exploration intuitive and user-friendly. Project Final Repositories
● Backend: STACHAT-BE ● Frontend: STACHAT-UI
● Answer questions about STAC Collections using natural language.
● Support for GPT-3.5-turbo and GPT-4-turbo models. (Multi-Model Support)
● Hybrid retrieval system combining Neo4j Vector Search and BM25.
● Dynamic response formatting with HTML for better readability.
