	### Dataset Summary

	This dataset contains the training, validation, and test data for the Shared Task 1: Acronym Identification of the AAAI-21 Workshop on Scientific Document Understanding.

	### Supported Tasks and Leaderboards

	The dataset supports an `acronym-identification` task, where the aim is to predic which tokens in a pre-tokenized sentence correspond to acronyms. The dataset was released for a Shared Task which supported a [leaderboard](https://competitions.codalab.org/competitions/26609).

	### Languages

	The sentences in the dataset are in English (`en`).

	## Dataset Structure

	### Data Instances

	A sample from the training set is provided below:

	```
	{'id': 'TR-0',
	'labels': [4, 4, 4, 4, 0, 2, 2, 4, 1, 4, 4, 4, 4, 4, 4, 4, 4, 4],
	'tokens': ['What',
	'is',
	'here',
	'called',
	'controlled',
	'natural',
	'language',
	'(',
	'CNL',
	')',
	'has',
	'traditionally',
	'been',
	'given',
	'many',
	'different',
	'names',
	'.']}
	```

	Please note that in test set sentences only the `id` and `tokens` fields are available. `labels` can be ignored for test set. Labels in the test set are all `O`

	### Data Fields

	The data instances have the following fields:

	- `id`: a `string` variable representing the example id, unique across the full dataset
	- `tokens`: a list of `string` variables representing the word-tokenized sentence
	- `labels`: a list of `categorical` variables with possible values `["B-long", "B-short", "I-long", "I-short", "O"]` corresponding to a BIO scheme. `-long` corresponds to the expanded acronym, such as controlled natural language here, and `-short` to the abbrviation, `CNL` here.

	### Data Splits

	The training, validation, and test set contain `14,006`, `1,717`, and `1750` sentences respectively.

	## Dataset Creation

	### Curation Rationale

	> First, most of the existing datasets for acronym identification (AI) are either limited in their sizes or created using simple rule-based methods.
	> This is unfortunate as rules are in general not able to capture all the diverse forms to express acronyms and their long forms in text.
	> Second, most of the existing datasets are in the medical domain, ignoring the challenges in other scientific domains.
	> In order to address these limitations this paper introduces two new datasets for Acronym Identification.
	> Notably, our datasets are annotated by human to achieve high quality and have substantially larger numbers of examples than the existing AI datasets in the non-medical domain.

	### Source Data

	#### Initial Data Collection and Normalization

	> In order to prepare a corpus for acronym annotation, we collect a corpus of 6,786 English papers from arXiv.
	> These papers consist of 2,031,592 sentences that would be used for data annotation for AI in this work.

	The dataset paper does not report the exact tokenization method.

	#### Who are the source language producers?

	The language was comes from papers hosted on the online digital archive [arXiv](https://arxiv.org/). No more information is available on the selection process or identity of the writers.

	### Annotations

	#### Annotation process

	> Each sentence for annotation needs to contain at least one word in which more than half of the characters in are capital letters (i.e., acronym candidates).
	> Afterward, we search for a sub-sequence of words in which the concatenation of the first one, two or three characters of the words (in the order of the words in the sub-sequence could form an acronym candidate.
	> We call the sub-sequence a long form candidate. If we cannot find any long form candidate, we remove the sentence.
	> Using this process, we end up with 17,506 sentences to be annotated manually by the annotators from Amazon Mechanical Turk (MTurk).
	> In particular, we create a HIT for each sentence and ask the workers to annotate the short forms and the long forms in the sentence.
	> In case of disagreements, if two out of three workers agree on an annotation, we use majority voting to decide the correct annotation.
	> Otherwise, a fourth annotator is hired to resolve the conflict

	#### Who are the annotators?

	Workers were recruited through Amazon MEchanical Turk and paid $0.05 per annotation. No further demographic information is provided.

	### Personal and Sensitive Information

	Papers published on arXiv are unlikely to contain much personal information, although some do include some poorly chosen examples revealing personal details, so the data should be used with care.
