| Challenge: | Pretrained language models (PLMs) achieve surprising performance on the Choice of Plausible Alternatives (COPA) task. |
| Approach: | They propose to add a regularization loss to the existing COPA models to mitigate the problem of semantic similarity bias by adding a normalization loss. |
| Outcome: | The proposed model improves generalization ability and performs better on a challenging dataset, BCOPA-CE, which has unbiased token distribution and is more difficult for models to distinguish cause and effect. |

| Challenge: | Recent work on incorporating external knowledge into the response generation models has attracted great interest. |
| Approach: | They propose a neural entity linking approach to incorporate external knowledge into the response generation models to improve the relevancy of retrieved knowledge. |
| Outcome: | The proposed approach outperforms the baseline model by 62.8% relative to the baseline. |
