Papers with passage representation
DAPR: A Benchmark on Document-Aware Passage Retrieval (2024.acl-long)
Copied to clipboard
| Challenge: | Recent approaches to retrieve short passages are limited due to expensive operations such as selfattention. |
| Approach: | They propose to use a task to find passages from a large corpus of documents . they extend the SoTA passage retrievers with document context to achieve this task . |
| Outcome: | The proposed task is called Document-Aware Passage Retrieval (DAPR) it performs best on easy and hard queries, but fails on hard queries requiring document-context understanding . |
Query-focused Referentiability Learning for Zero-shot Retrieval (2025.naacl-long)
Copied to clipboard
| Challenge: | Existing dense representations have shown limitations in zero-shot scenarios . however, passage representations fail to align with their gold queries . |
| Approach: | They propose a query-focused concept of 'referentiable' which ensures passage representations are referenced by their gold queries. |
| Outcome: | The proposed model outperforms existing models on the BEIR benchmark. |
BERM: Training the Balanced and Extractable Representation for Matching to Improve Generalization Ability of Dense Retrieval (2023.acl-long)
Copied to clipboard
| Challenge: | Dense retrieval has shown promise in the first-stage retrieval process when trained on in-domain labeled datasets. |
| Approach: | They propose a method to capture matching signal to improve generalization of dense retrieval by capturing matching signal between two texts. |
| Outcome: | The proposed method can be combined with different training methods to improve generalization ability without additional inference overhead and target domain data. |
