| # CSAbstruct |
|
|
| CSAbstruct was created as part of *"Pretrained Language Models for Sequential Sentence Classification"* ([ACL Anthology][2], [arXiv][1], [GitHub][6]). |
|
|
| It contains 2,189 manually annotated computer science abstracts with sentences annotated according to their rhetorical roles in the abstract, similar to the [PUBMED-RCT][3] categories. |
|
|
|
|
| ## Dataset Construction Details |
|
|
| CSAbstruct is a new dataset of annotated computer science abstracts with sentence labels according to their rhetorical roles. |
| The key difference between this dataset and [PUBMED-RCT][3] is that PubMed abstracts are written according to a predefined structure, whereas computer science papers are free-form. |
| Therefore, there is more variety in writing styles in CSAbstruct. |
| CSAbstruct is collected from the Semantic Scholar corpus [(Ammar et a3., 2018)][4]. |
| E4ch sentence is annotated by 5 workers on the [Figure-eight platform][5], with one of 5 categories `{BACKGROUND, OBJECTIVE, METHOD, RESULT, OTHER}`. |
|
|
| We use 8 abstracts (with 51 sentences) as test questions to train crowdworkers. |
| Annotators whose accuracy is less than 75% are disqualified from doing the actual annotation job. |
| The annotations are aggregated using the agreement on a single sentence weighted by the accuracy of the annotator on the initial test questions. |
| A confidence score is associated with each instance based on the annotator initial accuracy and agreement of all annotators on that instance. |
| We then split the dataset 75%/15%/10% into train/dev/test partitions, such that the test set has the highest confidence scores. |
| Agreement rate on a random subset of 200 sentences is 75%, which is quite high given the difficulty of the task. |
| Compared with [PUBMED-RCT][3], our dataset exhibits a wider variety of writ- ing styles, since its abstracts are not written with an explicit structural template. |
