Dataset Description

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
  • Total amount of disk used: 366.8 MB

An example of 'train' looks as follows.

{
    '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), ...
