	### Dataset Summary

	CovidQA is a question answering dataset specifically designed for COVID-19, built by hand from knowledge gathered
	from Kaggle’s COVID-19 Open Research Dataset Challenge.
	The dataset comprises 156 question-article pairs with 27 questions (topics) and 85 unique articles.

	### Supported Tasks and Leaderboards

	[More Information Needed]

	### Languages

	The text in the dataset is in English.

	## Dataset Structure

	### Data Instances

	What do the instances that comprise the dataset represent?
	Each represents a question, a context (document passage from the CORD19 dataset) and an answer.

	How many instances are there in total?

	What data does each instance consist of?
	Each instance is a query (natural language question and keyword-based), a set of answers, and a document id with its title associated with each answer.

	[More Information Needed]

	### Data Fields

	The data was annotated in SQuAD style fashion, where each row contains:

	* question_query: Natural language question query
	* keyword_query: Keyword-based query
	* category_name: Category in which the queries are part of
	* answers: List of answers
	* id: The document ID the answer is found on
	* title: Title of the document of the answer
	* exact_answer: Text (string) of the exact answer

	### Data Splits

	data/kaggle-lit-review-0.2.json: 156 question-article pairs with 27 questions (topics) and 85 unique articles from
	CORD-19.

	[More Information Needed]

	## Dataset Creation

	The dataset aims to help for guiding research until more substantial evaluation resources become available. Being a smaller dataset,
	it can be helpful for evaluating the zero-shot or transfer capabilities of existing models on topics specifically related to COVID-19.

	### Curation Rationale

	[More Information Needed]

	### Source Data

	#### Initial Data Collection and Normalization

	#### Who are the source language producers?

	[More Information Needed]

	### Annotations

	Five of the co-authors participated in this annotation effort, applying the aforementioned approach, with one lead
	annotator responsible for approving topics and answering technical questions from the other annotators. Two annotators are
	undergraduate students majoring in computer science, one is a science alumna, another is a computer science professor,
	and the lead annotator is a graduate student in computer science—all affiliated with the University of Waterloo.

	#### Annotation process

	#### Who are the annotators?

	### Personal and Sensitive Information

	[More Information Needed]

	## Considerations for Using the Data

	### Social Impact of Dataset

	The dataset was intended as a stopgap measure for guiding research until more substantial evaluation resources become available.

	### Discussion of Biases

	[More Information Needed]

	### Other Known Limitations

	While this dataset, comprising 124 question–article pairs as of the present version 0.1 release, does not have sufficient
	examples for supervised machine learning, it can be helpful for evaluating the zero-shot or transfer capabilities
	of existing models on topics specifically related to COVID-19.

	## Additional Information

	The listed authors in the homepage are maintaining/supporting the dataset.
