TRIAL: Token Relations and Importance Aware Late-interaction for Accurate Text Retrieval (2025.emnlp-main)
Copied to clipboard
| Challenge: | Late-interaction based multi-vector retrieval systems rely on a naive summation of token-level similarity scores . this leads to inaccurate relevance estimation due to tokenization of semantic units and the influence of low-content words. |
| Approach: | They propose a late-interaction-based multi-vector retrieval system that uses token relations and token importance in relevance scoring. |
| Outcome: | Extensive tests show that TRIAL achieves state-of-the-art accuracy compared to existing methods. |
