| Challenge: | Existing evaluations of QG methods rely on single reference-based similarity metrics . multiple (pseudo) references are more effective for QG evaluation . |
| Approach: | They propose to paraphrase the reference question for a more robust QG evaluation. |
| Outcome: | The proposed frameworks show higher correlation with human evaluations than evaluation with a single reference. |

| Challenge: | Existing methods to improve text classification in education suffer from data scarcity . authors propose a retrieval approach that provides effective learning in educational text classification. |
| Approach: | They propose a retrieval approach that provides effective learning in educational text classification by introducing cross-encoder style texts to a bi-encoding architecture. |
| Outcome: | The proposed method is effective in multi-label scenarios and low-resource tags compared to state-of-the-art models. |
