RAGxplorer - Open-source RAG Visualization Tool 🔮

Project Overview

RAGxplorer is an open-source tool specifically designed for visualizing Retrieval Augmented Generation (RAG) systems. Developed by Gabriel Chua, this project aims to help developers and researchers better understand and debug the document retrieval and semantic similarity matching processes within RAG applications.

Key Features

1. Document Processing and Loading

• PDF Document Support: Directly load PDF files for processing
• Document Chunking: Automatically split documents into text chunks suitable for vectorization
• Multiple Document Format Support: Extended support for various document formats

2. Vector Embedding Visualization

• Embedding Space Visualization: Visualize the representation of document chunks in vector space
• Semantic Similarity Exploration: Intuitively display semantic relationships between document chunks
• Multiple Embedding Model Support: Support for various pre-trained embedding models

3. Query Visualization

• Query Matching Visualization: Display the matching process between queries and document chunks
• Similarity Score Display: Intuitively show the relevance scores of retrieval results
• Interactive Query: Support real-time querying and result visualization

Technical Features

Core Technology Stack

• Python: Primary development language
• Streamlit: Web interface framework
