# 🧠 LLM-QE: Improving Query Expansion by Aligning Large Language Models with Ranking Preferences

This is the official model for **[LLM-QE: Improving Query Expansion by Aligning Large Language Models with Ranking Preferences](https://arxiv.org/abs/2502.17057)**.  

The LLM-QE model is designed to enhance **query expansion** in **information retrieval** tasks by leveraging **Large Language Models (LLMs)**, improving the **alignment between LLMs and ranking preferences** during query expansion.
