PathRAG implements a novel retrieval-augmented generation (RAG) system that leverages graph-based relational paths to prune irrelevant information, enhancing the efficiency and accuracy of large language model responses. It is designed for researchers and developers working with complex, interconnected data who need to improve RAG performance.

How It Works

PathRAG constructs a graph from input documents, representing relationships between entities. It then utilizes these relational paths to intelligently prune the search space during retrieval, focusing on contextually relevant information. This graph-based pruning approach aims to reduce noise and improve the signal-to-noise ratio for the LLM.

Quick Start & Requirements

• Install via pip install -e . after cloning the repository.
• Requires an OpenAI API key for LLM interaction.
• Example usage provided in v1_test.py.
• Supports batch insertion of .txt files.

Highlighted Details

• Graph-based pruning of retrieval context.
