Papers with overlapping phrase problem
Incorporating Linguistic Constraints into Keyphrase Generation (P19-1)
Copied to clipboard
| Challenge: | Existing keyphrase generation methods generate overlapping phrases (including sub-phrases or super-phrase) Existing methods are far from satisfactory for a wide range of natural language processing tasks. |
| Approach: | They propose a parallel Seq2Seq network with coverage attention to alleviate the overlapping phrase problem by integrating linguistic constraints of keyphrase into the basic Seq2-Sequeq network on the source side and employ the multi-task learning framework on the target side. |
| Outcome: | The proposed method outperforms the state-of-the-art CopyRNN on scientific datasets and is also more effective in news domain. |
