### Dataset Summary
MultiReQA contains the sentence boundary annotation from eight publicly available QA datasets including SearchQA, TriviaQA, HotpotQA, NaturalQuestions, SQuAD, BioASQ, RelationExtraction, and TextbookQA. Five of these datasets, including SearchQA, TriviaQA, HotpotQA, NaturalQuestions, SQuAD, contain both training and test data, and three, in cluding BioASQ, RelationExtraction, TextbookQA, contain only the test data (also includes DuoRC but not specified in the official documentation)
### Supported Tasks and Leaderboards

- Question answering (QA)
- Retrieval question answering (ReQA)
### Languages

Sentence boundary annotation for SearchQA, TriviaQA, HotpotQA, NaturalQuestions, SQuAD, BioASQ, RelationExtraction, TextbookQA and DuoRC

## Dataset Structure

### Data Instances

The general format is:
`
{
  "candidate_id": <candidate_id>,
  "response_start": <response_start>,
  "response_end": <response_end>
}
...
`

An example from SearchQA:
`{'candidate_id': 'SearchQA_000077f3912049dfb4511db271697bad/_0_1',
 'response_end': 306,
 'response_start': 243} `

### Data Fields

`
{
  "candidate_id": <STRING>,
  "response_start": <INT>,
  "response_end": <INT>
}
...
`
-  **candidate_id:**  The candidate id of the candidate sentence. It consists of the original qid from the MRQA shared task.
-   **response_start:**  The start index of the sentence with respect to its original context.
-   **response_end:**  The end index of the sentence with respect to its original context

### Data Splits

Train and Dev splits are available only for the following datasets,
 - SearchQA
 - TriviaQA
 - HotpotQA
 - SQuAD 
 - NaturalQuestions

Test splits are available only for the following datasets,
 - BioASQ
 - RelationExtraction
 - TextbookQA

The number of candidate sentences for each dataset in the table below.

## Dataset Creation

### Curation Rationale

MultiReQA is a new multi-domain ReQA evaluation suite composed of eight retrieval QA tasks drawn from publicly available QA datasets from the [MRQA shared task](https://mrqa.github.io/). The dataset was curated by converting existing QA datasets from [MRQA shared task](https://mrqa.github.io/) to the format of MultiReQA benchmark.
### Source Data

#### Initial Data Collection and Normalization

The Initial data collection was performed by  converting existing QA datasets from MRQA shared task to the format of MultiReQA benchmark.
