| 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 evaluation metrics for MCQ generation focus on the n-gram based similarity of the generated MCq to the gold sample and disregard their educational value. |
| Approach: | They propose to use a human survey to measure the MCQ’s answerability given knowledge of the target fact. |
| Outcome: | The proposed methods measure the MCQ’s answerability given knowledge of the target fact. |
Structure-Augmented Keyphrase Generation (2021.emnlp-main)
Copied to clipboard
| Challenge: | Creating keyphrases that are likely to be words absent from the given document is challenging . |
| Approach: | They propose novel keyphrase generation tasks that augment missing context by adding keyphrases to documents. |
| Outcome: | The proposed keyphrase generation task outperforms the state-of-the-art in two keyphrase tasks. |

| 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. |
