Appendix: model implementation and evaluation details.
Dataset Statistics
| train/val/test examples | average document length | summary length | number of references |
|---|---|---|---|
| 30,369/5,066/5,093 | 778.08 | 116.44 | 4.42 |
We also calculate the percentage of novel n-grams in the target summary of previous datasets. Three of them are single-document summarization datasets. Our dataset has the highest abstractiveness among all existing multi-document summarization datasets.
| Datasets | % of novel unigram | % of novel bi-grams | % of novel tri-grams | % of novel 4-grams |
|---|---|---|---|---|
| CNN-DailyMail (single) | 17.00 | 53.91 | 71.98 | 80.29 |
| NY Times (single) | 22.64 | 55.59 | 71.93 | 80.16 |
| XSum (single) | 35.76 | 83.45 | 95.50 | 98.49 |
| WikiSum | 18.20 | 51.88 | 69.82 | 78.16 |
| Multi-News | 17.76 | 57.10 | 75.71 | 82.30 |
| Multi-XScience | 42.33 | 81.75 | 94.57 | 97.62 |
Dataset Format
| key | description |
|---|---|
| aid | arxiv id (e.g. 2010.14235) |
