Conversational Query Reformulation (CQR) can be improved by leveraging key information extracted from initially retrieved documents to generate more retriever-friendly queries.

The paper proposes GuideCQR, a novel framework for conversational query reformulation that utilizes the guidance of initially retrieved documents to generate more effective queries for conversational search.
The key steps of GuideCQR are:
- Retrieving an initial set of guided documents using a baseline query reformulated by a large language model (LLM).
- Extracting keywords and generating expected answers from the re-ranked guided documents to create components that can enhance the retriever-friendliness of the final query.
- Applying a filtering process to remove irrelevant keywords and answers based on their similarity to the baseline query and dialogue history.
- Unifying the filtered keywords and answers with the baseline query to construct the final reformulated query.
Experimental results show that GuideCQR achieves state-of-the-art performance across multiple conversational search datasets, outperforming previous CQR methods. The framework also demonstrates robustness and adaptability, improving performance on both human-rewritten queries and raw queries.
