Exploiting Pre-Ordering for Neural Machine Translation (L18-1)
Copied to clipboard
| Challenge: | Existing studies have shown that Neural Machine Translation suffers from the problems that some source words are mistakenly translated for multiple times . |
| Approach: | They propose a pre-ordering approach to solve the under-translation problem by pre-ordnanced source sentences and position embedding to enhance monotone translation. |
| Outcome: | The proposed method significantly improves translation quality by 2.43 BLEU points on Chinese-to-English translation. |
The Summary Loop: Learning to Write Abstractive Summaries Without Examples (2020.acl-main)
Copied to clipboard
| Challenge: | Unsupervised abstractive summarization is important for news headlines and research papers . a novel method that encourages the inclusion of key terms from the original document into the summary is presented . |
| Approach: | They propose a method that encourages the inclusion of key terms from the original document into the summary by a coverage model along with a fluency model. |
| Outcome: | The proposed method outperforms existing methods on news summarization datasets and is competitive with existing methods. |
