Description of contents:

Data Description:

data/: Raw annotations created with the BRAT annotation tool. Every annotated paper contains a .ann and a .txt file. The .ann file contains, entity and relation annotations. The .txt file contains 3 lines, the doi of the paper, the title of the paper and the synthesis-procedure text of the paper. This directory contains annotations for 230 papers. The annotations are in the BRAT Standoff format.

fex-{dev/test}-fnames.txt: The files in the "data/" subdirectory corresponding to the dev and test splits for an unsupervised frame extraction (fex) task. Since the task is primarily trained on unlabelled data we only release test and development data.

ner-{dev/test/train}-fnames.txt: The files in the "data/" subdirectory corresponding to the dev, test and train files for the named entity extraction (ner) task.

sfex-{dev/test/train}-fnames.txt: The files in the "data/" subdirectory corresponding to the dev, test and train files for the supervised frame extraction task.

Dataset statistics:

ent2count-sorted.txt: The entities labelled in the data vs the number of times these entities were labelled.

etype2count-sorted.txt: The entity types labelled vs the number of times these entity types were labelled.

sentcount2papercount-sorted.txt: The number of sentences that in a given synthesis procedure vs the number of papers with the said number of sentences. Sentence segmentation was performed automatically with the ChemDataExtractor python package.

sentlen2sentcount-sorted.txt: The number of tokens in a sentence vs the number of sentences with the said number of tokens. Sentence tokenization was performed automatically with the ChemDataExtractor tool.

tok2count-sorted.txt: The tokens vs the number of times the tokens occur in the dataset. Sentence tokenization was performed automatically with the ChemDataExtractor tool.
