Hierarchical User Intent Inference with Knowledge Graph Grounding (2026.findings-eacl)
Copied to clipboard
| Challenge: | Existing large language models lack structured grounding and do not capture nuanced intent expression. |
| Approach: | They propose a Hierarchical Intent Inference framework that first predicts fine-grained aspect ratings and then generates natural language intent statements guided by contextual subgraphs retrieved from a domain-specific knowledge graph. |
| Outcome: | The proposed framework outperforms strong LLM and encoder-based baselines on a hotel review dataset. |
