| | ### Dataset Summary |
| | |
| | FewRel is a large-scale few-shot relation extraction dataset, which contains more than one hundred relations and tens of thousands of annotated instances cross different domains. |
| | |
| | ### Supported Tasks and Leaderboards |
| | |
| | [Needs More Information] |
| | |
| | ### Languages |
| | |
| | The dataset contaings English text, as used by writers on Wikipedia, and crowdsourced English annotations. |
| | |
| | ## Dataset Structure |
| | |
| | |
| | ### Data Instances |
| | |
| | An instance from `train_wiki` split: |
| |
|
| | ``` |
| | {'head': {'indices': [[16]], 'text': 'tjq', 'type': 'Q1331049'}, 'names': ['place served by transport hub', 'territorial entity or entities served by this transport hub (airport, train station, etc.)'], 'relation': 'P931', 'tail': {'indices': [[13, 14]], 'text': 'tanjung pandan', 'type': 'Q3056359'}, 'tokens': ['Merpati', 'flight', '106', 'departed', 'Jakarta', '(', 'CGK', ')', 'on', 'a', 'domestic', 'flight', 'to', 'Tanjung', 'Pandan', '(', 'TJQ', ')', '.']} |
| | ``` |
| |
|
| | ### Data Fields |
| |
|
| | For `default`: |
| |
|
| | - `relation`: a `string` feature containing PID of the relation. |
| | - `tokens`: a `list` of `string` features containing tokens for the text. |
| | - `head`: a dictionary containing: |
| | - `text`: a `string` feature representing the head entity. |
| | - `type`: a `string` feature representing the type of the head entity. |
| | - `indices`: a `list` containing `list` of token indices. |
| |
|
| | - `tail`: a dictionary containing: |
| | - `text`: a `string` feature representing the tail entity. |
| | - `type`: a `string` feature representing the type of the tail entity. |
| | - `indices`: a `list` containing `list` of token indices. |
| | - `names`: a `list` of `string` features containing relation names. For `pubmed_unsupervised` split, this is set to a `list` with an empty `string`. For `val_semeval` and `val_pubmed` split, this is set to a `list` with the `string` from the `relation` field. |
| |
|
| | ### Data Splits |
| |
|
| | `train_wiki`: 44800 |
| | `val_nyt`: 2500 |
| | `val_pubmed`: 1000 |
| | `val_semeval`: 8851 |
| | `val_wiki`: 11200 |
| | `pubmed_unsupervised`: 2500 |
