Dataset Card for MultiReQA

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)

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

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. The dataset was curated by converting existing QA datasets from MRQA shared task to the format of MultiReQA benchmark.

Source Data

Initial Data Collection and Normalization
