Multi-Domain Dialogue State Tracking with Disentangled Domain-Slot Attention (2023.findings-acl)
Copied to clipboard
| Challenge: | Multi-domain dialogue state tracking is a challenge for task-oriented dialogue systems . domains and slots are aggregated into a single query to generate domain-slot specific representations . |
| Approach: | They propose to disentangle domain-slot attention for multi-domain dialogue state tracking by separating query about domains and slots from the attention component. |
| Outcome: | The proposed approach outperforms the standard multi-head attention with aggregated domain-slot query. |

| Challenge: | Existing methods to extract opinion words from sentences are limited due to the expensive annotation process. |
| Approach: | They propose to exploit massive unlabeled data to reduce distribution shift risk . they propose to use two filters specifically for TOWE to filter noisy data . results indicate superiority of MGCR over current state-of-the-art methods . |
| Outcome: | The proposed method reduces the risk of distribution shifts by increasing the exposure of the model to varying distribution shift. |
