In this study, we propose a method for retrieving concrete reviews for a product, using an abstract review as a query. However, it is difficult to retrieve concrete reviews from keywords or abstract reviews, as simple sparse or dense retrieval methods cannot account for concreteness. Therefore, we propose a method called Query Rewriting with Retrieved Review Concretization (QR-ReReC), which utilizes retrieved reviews to rewrite the original query. For the experiment, we constructed a dataset to evaluate the effectiveness of QR-ReReC. The results showed that QR-ReReC is more effective for retrieving more concrete reviews than the retrieval methods without query rewriting and pseudo relevance feedback.
