RAG Query Transformation Dataset

Description

This dataset contains synthetic query transformations generated to improve retrieval quality in Retrieval-Augmented Generation (RAG) systems.

Each original query is paired with four transformed variants:

paraphrase
broader
technical
explicit

Source

Base queries: MS MARCO
Transformations: LLM-generated (Gemini Flash Lite)

Size

~66k original queries
~264k total transformed queries

Intended Use

Query expansion
Embedding-based retrieval
Training lightweight models (e.g., VAE) for query transformation

Limitations

Synthetic data
Some noise may be present
Not intended for direct QA
