Towards Answer-unaware Conversational Question Generation (D19-58)
Copied to clipboard
| Challenge: | Existing frameworks for conversational question generation are answeraware, but are not able to generate corresponding answers . a number of question generation methods are developed for text-based question answering . |
| Approach: | They propose a framework for conversational question generation that is unaware of the corresponding answers. |
| Outcome: | The proposed framework is effective but answeraware, the authors show . it improves quality of generated questions if question foci and question patterns are identified . |
Answerable or Not: Devising a Dataset for Extending Machine Reading Comprehension (C18-1)
Copied to clipboard
| Challenge: | Existing MRC algorithms assume that each question is answerable by looking at text passages, but to realize human-like language comprehension ability, a machine should be able to distinguish not-answerable questions from answerable questions. |
| Approach: | They propose a method for automatically assigning difficulty level labels to a dataset that alters an existing MRC dataset and describes the resulting dataset. |
| Outcome: | The proposed method can detect NAQs in a dataset with difficulty level labels and is valid and potentially useful in the development of advanced MRC models. |
