Realizing Universal Dependencies Structures (D19-63)
Copied to clipboard
| Challenge: | UD-SURFR is a symbolic surface realizer for Universal Dependencies structures . it is based on a tree of constituents that is then converted into an English sentence . |
| Approach: | They propose a symbolic system that transforms a dependency tree into a tree of constituents that is transformed into an English sentence by an existing realizer. |
| Outcome: | The proposed system is quite fast and showed competitive results for English sentences using automatic and manual evaluation measures. |
Unsupervised multiple-choice question generation for out-of-domain Q&A fine-tuning (2022.acl-short)
Copied to clipboard
| Challenge: | Pre-trained models have shown very good performances on a number of question answering benchmarks especially when fine-tuned on multiple question answering datasets at once. |
| Approach: | They propose an approach to fine-tune a question-answering dataset using a rule-based algorithm that generates questions and answers from unannotated sentences. |
| Outcome: | The proposed model can generate questions and answers from unannotated sentences on a multiple-choice physics, biology and chemistry benchmark. |
