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.

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.
