Papers with Generative Retrieval
D3: Dynamic Docid Decoding for Multi-Intent Generative Retrieval (2026.eacl-industry)
Copied to clipboard
| Challenge: | Existing GR systems rely on offline DocID assignment and constrained decoding . offline Doc ID assignment and decoding often prevents GR from capturing query-specific intent . |
| Approach: | They propose a mechanism that adaptively refines DocIDs through query-informed identifier expansion. |
| Outcome: | The proposed mechanism improves retrieval accuracy on unseen and multi-intent documents. |
Generative Dense Retrieval: Memory Can Be a Burden (2024.eacl-long)
Copied to clipboard
| Challenge: | Empirical results show that Generative Dense Retrieval (GDR) achieves an average of 3.0 R@100 improvement on NQ dataset under multiple settings and has better scalability. |
| Approach: | They propose a Generative Dense Retrieval paradigm that auto-decodes document identifiers given a query and uses memory to avoid memory confusion. |
| Outcome: | Empirical results show that the proposed paradigm improves on the small-scale corpora and improves scalability. |
FinSight: Towards Real-World Financial Deep Research (2026.acl-long)
Copied to clipboard
| Challenge: | FinSight is the first multi-agent framework for automating end-to-end professional, multimodal financial reports. |
| Approach: | They propose a code agent with variable memory architecture that unifies data, tools, and agents into a programmable variable space. |
| Outcome: | The proposed framework outperforms leading deep research systems in factual accuracy, analytical depth, and presentation quality. |

| Challenge: | Existing methods generate DocIDs based on textual content, which may result in weak semantic connections for similar documents due to variations in expression. |
| Approach: | They propose a new retrieval paradigm that generates unique document identifiers . they propose to use queries as a bridge to connect documents with varying relevance levels . |
| Outcome: | The proposed approach outperforms existing methods on multilingual e-commerce search datasets. |
Generative Text-to-Image Retrieval via Hierarchical Identifiers and Semantic Internalization (2026.findings-acl)
Copied to clipboard
| Challenge: | Existing text-to-image retrieval methods suffer from limited semantic discriminability, alignment bias, and closed-set restrictions. |
| Approach: | They propose a framework for semantic internalization for Generative Multimodal Alignment . they construct multi-granularity hierarchical identifiers to ensure unique, semantically consistent image representations . |
| Outcome: | The proposed framework outperforms state-of-the-art frameworks on Flickr30K and MS-COCO datasets . it achieves average Recall@1, Recall @5, and Recall_10 improvements of 10.65%, 8.50%, and 7.00% . |
