	## Dataset Structure

	### Data Instances

	The original dataset was published with the following json structure:
	```

	"title": <str>
	},

	]
	},
	...
	]
	}
	```

	*docId* The docID is the identifier of the document. This is unique to the document, and can be resolved into a URL
	for the document through the addition of `https//www.sciencedirect.com/science/pii/<docId>`

	*abstract* This is the author provided abstract for the document

	*body_text* The full text for the document. The text has been split on sentence boundaries, thus making it easier to
	use across research projects. Each sentence has the title (and ID) of the section which it is from, along with titles (and
	IDs) of the parent section. The highest-level section takes index 0 in the parents array. If the array is empty then the
	title of the section for the sentence is the highest level section title. This will allow for the reconstruction of the article
	structure. References have been extracted from the sentences. The IDs of the extracted reference and their respective
	offset within the sentence can be found in the “refoffsets” field. The complete list of references are can be found in
	the “bib_entry” field along with the references’ respective metadata. Some will be missing as we only keep ‘clean’
	sentences,

	*bib_entities* All the references from within the document can be found in this section. If the meta data for the
	reference is available, it has been added against the key for the reference. Where possible information such as the
	document titles, authors, and relevant identifiers (DOI and PMID) are included. The keys for each reference can be
	found in the sentence where the reference is used with the start and end offset of where in the sentence that reference
	was used.

	*metadata* Meta data includes additional information about the article, such as list of authors, relevant IDs (DOI and
	PMID). Along with a number of classification schemes such as ASJC and Subject Classification.

	*author_highlights* Author highlights were included in the corpus where the author(s) have provided them. The
	coverage is 61% of all articles. The author highlights, consisting of 4 to 6 sentences, is provided by the author with
	the aim of summarising the core findings and results in the article.

	### Data Fields

	* *title*: This is the author provided title for the document. 100% coverage.
	* *abstract*: This is the author provided abstract for the document. 99.25% coverage.
	* *keywords*: This is the author and publisher provided keywords for the document. 100% coverage.
	* *asjc*: This is the disciplines for the document as represented by 334 ASJC (All Science Journal Classification) codes. 100% coverage.
	* *subjareas*: This is the Subject Classification for the document as represented by 27 ASJC top-level subject classifications. 100% coverage.
	* *body_text*: The full text for the document. 100% coverage.
	* *author_highlights*: This is the author provided highlights for the document. 61.31% coverage.

	### Data Splits
