UCGRec: User-Centric Graph Learning for LLM-based Sequential Recommendation (2026.findings-acl)
Copied to clipboard
| Challenge: | Existing methods for sequential recommendation rely primarily on item descriptions or utilize user preferences independently. |
| Approach: | They propose a method that integrates diverse user-relevant preference signals into a unified user-centric graph and injects the graph-based knowledge into the LLM through end-to-end training with graph neural networks. |
| Outcome: | The proposed method outperforms conventional and state-of-the-art methods on four widely used sequential real-world recommendation datasets. |
