Data Instances


  • Size of downloaded dataset files: 492.15 MB
  • Size of the generated dataset: 1989.22 MB
  • Total amount of disk used: 2481.37 MB

An example of 'validation' looks as follows.

    "answers": [],
    "context": "answer",
    "question": "What is XXX in this question?",
    "relation": "relation_name",
    "subject": "Some entity Here is a bit of context which will explain the question in some way"

Data Fields

The data fields are the same among all splits.


  • relation: a string feature.
  • question: a string feature.
  • subject: a string feature.
  • context: a string feature.
  • answers: a list of string features.
