# KP20k Benchmark Dataset for Keyphrase Generation |
|
|
|
## About |
|
|
|
KP20k is a dataset for benchmarking keyphrase extraction and generation models. |
|
The data is composed of 570 809 abstracts and their associated titles from scientific articles. |
|
|
|
Details about the dataset can be found in the original paper: |
|
- Meng et al 2017. |

|
Proceedings of the 55th Annual Meeting of the Association for Computational Linguistics, pages 582–592 |
|
|
|
Reference (indexer-assigned) keyphrases are also categorized under the PRMU (<u>P</u>resent-<u>R</u>eordered-<u>M</u>ixed-<u>U</u>nseen) scheme as proposed in the following paper: |
|
- Florian Boudin and Ygor Gallina. 2021. |

## Content |

|
|
The dataset is divided into the following three splits: |
|

The following data fields are available: |
|
- **id**: unique identifier of the document. **NB** There were no ids in the original dataset. The ids were generated using the python module shortuuid (https://pypi.org/project/shortuuid/) |
|
- **title**: title of the document. |
|
- **abstract**: abstract of the document. |
|
- **keyphrases**: list of reference keyphrases. |
|
- **prmu**: list of <u>P</u>resent-<u>R</u>eordered-<u>M</u>ixed-<u>U</u>nseen categories for reference keyphrases. |
