# Data

### Original source
All question-answer pairs were obtained from the [DPR](https://github.com/facebookresearch/DPR) repository.

### Data format

The expected data format is a list of entry examples, where each entry example is a dictionary containing
- `question`: question text
- `reference`: list of answer text for evaluation
- `ctxs`: a list of passages

Entry example:
```
{
  'question': 'who got the first nobel prize in physics',
  'answers': ['Wilhelm Conrad Röntgen'],
  'ctxs': [
            "Wilhelm Conrad Röntgen won first Nobel Prize in Physics.",
            "Wilhelm Conrad Röntgen won it for discovery of X-rays",
            "Albert Einstein was awarded the 1921 Nobel Prize in Physics",
            "The Nobel Prize in Physics is a yearly award.",
            "First law of thermodynamics was stated by William"
          ]
}
```
