Copied to clipboard
| Challenge: | Existing methods for document summarization use extractive and abstractive representations, but they don't take into account hierarchical structure of document clusters. |
| Approach: | They propose a multi-granularity interaction network for extractive and abstractive multi-document summarization which jointly learn semantic representations for words, sentences, and documents. |
| Outcome: | The proposed model outperforms baseline methods and achieves the best results on the Multi-News dataset. |
