| ### Dataset Summary | |
| This script is for loading the Few-NERD dataset from https://ningding97.github.io/fewnerd/. | |
| Few-NERD is a large-scale, fine-grained manually annotated named entity recognition dataset, which contains 8 coarse-grained types, 66 fine-grained types, 188,200 sentences, 491,711 entities, and 4,601,223 tokens. Three benchmark tasks are built, one is supervised (Few-NERD (SUP)) and the other two are few-shot (Few-NERD (INTRA) and Few-NERD (INTER)). | |
| NER tags use the `IO` tagging scheme. The original data uses a 2-column CoNLL-style format, with empty lines to separate sentences. DOCSTART information is not provided since the sentences are randomly ordered. | |
| For more details see https://ningding97.github.io/fewnerd/ and https://aclanthology.org/2021.acl-long.248/. | |

| ## Dataset Structure | |
| ### Data Instances | |
| - **Size of downloaded dataset files:** | |
| - `super`: 14.6 MB | |
| - `intra`: 11.4 MB | |
| - `inter`: 11.5 MB | |
| - **Size of the generated dataset:** | |
| - `super`: 116.9 MB | |
| - `intra`: 106.2 MB | |
| - `inter`: 106.2 MB | |

| An example of 'train' looks as follows. | |
| ```json | |
| { | |
| 'id': '1', | |
| 'tokens': ['It', 'starred', 'Hicks', "'s", 'wife', ',', 'Ellaline', 'Terriss', 'and', 'Edmund', 'Payne', '.'], | |
| 'ner_tags': [0, 0, 7, 0, 0, 0, 7, 7, 0, 7, 7, 0], | |
| 'fine_ner_tags': [0, 0, 51, 0, 0, 0, 50, 50, 0, 50, 50, 0] | |
| } | |
| ``` | |
| ### Data Fields | |
| The data fields are the same among all splits. | |
| - `id`: a `string` feature. | |
| - `tokens`: a `list` of `string` features. | |
| - `ner_tags`: a `list` of classification labels, with possible values including `O` (0), `art` (1), `building` (2), `event` (3), `location` (4), `organization` (5), `other`(6), `person` (7), `product` (8) | |
| - `fine_ner_tags`: a `list` of fine-grained classification labels, with possible values including `O` (0), `art-broadcastprogram` (1), `art-film` (2), ... | |
