	### Dataset Structure

	#### Data Fields

	<!-- info: List and describe the fields present in the dataset. -->
	<!-- scope: telescope -->
	- `Document`: Input news article.
	- `Summary`: One sentence summary of the article.
	- `Id`: BBC ID of the article.

	#### Reason for Structure

	<!-- info: How was the dataset structure determined? -->
	<!-- scope: microscope -->
	The Document/Summary format is standard for summarization datasets.

	#### How were labels chosen?

	<!-- info: How were the labels chosen? -->
	<!-- scope: microscope -->
	The labels are the first sentence of the source article.

	#### Example Instance

	<!-- info: Provide a JSON formatted example of a typical instance in the dataset. -->
	<!-- scope: periscope -->
	```
	{
	'document': 'The researchers have sequenced the genome of a strain of bacterium that causes the virulent infection.\nA survey in 2007 showed that bleeding canker had spread rapidly, with almost half of the two million horse chestnuts displaying symptoms of the disease.\nThe findings have been published in the journal PLoS One.\nA visible symptom of the disease is a lesion on the bark, which oozes a resin on to the trunk or sometimes the branches.\nThe bark underneath the canker is killed, and if cankers manage to go all the way around the trunk then the horse chestnut (Aesculus hippocastanum) will die because it cuts off the food supply. [...]',
	'target': "A team of UK scientists hopes to shed light on the mysteries of bleeding canker, a disease that is threatening the nation's horse chestnut trees.",
	}
	```

	#### Data Splits

	<!-- info: Describe and name the splits in the dataset if there are more than one. -->
	<!-- scope: periscope -->
	\| Section \| Number of Documents \|

	\| Training \| 204,045 \|
	\| Validation \| 11,332 \|
	\| Testing \| 11,334 \|
	\| Total \| 226k \|

	\| Section \| number of words\| number of sentences \|
	\| ------------- \|:-------------:\| :-------------:\|
	\| Documents \| 431.07 \| 19.77 \|
	\| Summary \| 23.26 \| 1.00 \|


	#### Splitting Criteria

	<!-- info: Describe any criteria for splitting the data, if used. If there are differences between the splits (e.g., if the training annotations are machine-generated and the dev and test ones are created by humans, or if different numbers of annotators contributed to each example), describe them here. -->
	<!-- scope: microscope -->
	The identifiers in the URLs were used to randomly split the dataset into training (90%, 204,045), validation (5%, 11,332), and test (5%, 11,334) sets.



	## Dataset Curation

	### Original Curation

	#### Original Curation Rationale

	<!-- info: Original curation rationale -->
	<!-- scope: telescope -->
	Comparable datasets are often very extractive which is not a strategy that works for one-sentence summaries. The dataset curators thus created this dataset as a way to evaluate truly abstractive models

	#### Communicative Goal

	<!-- info: What was the communicative goal? -->
	<!-- scope: periscope -->
	Same as the communicative goal in GEM: A model should summarize a news article in a single sentence

	<!-- scope: periscope -->
	The language and content of the data is focused on news and language in the UK and as such not representative of the speakers world-wide. Existing selection biases of the BBC exist in this dataset.
