Source A have 860 essays available from August 2015 to March 2020.
For each month of that period, a new prompt together with supporting texts were given, and the graded essays from the previous month were made available.
Of the 56 prompts, 12 had no associated essays available (at the time of download).
Additionally, there were 3 prompts that asked for a text in the format of a letter. We removed those 15 prompts and associated texts from the corpus.
For an unknown reason, 414 of the essays were graded using a five-point scale of either {0, 50, 100, 150, 200} or its scaled-down version going from 0 to 2.
To avoid introducing bias, we also discarded such instances, resulting in a dataset of 386 annotated essays with prompts and supporting texts (with each component being clearly identified).
Some of the essays used a six-point scale with 20 points instead of 40 points as the second class. As we believe this introduces minimal bias, we kept such essays and relabeled class 20 as class 40.
The original data contains comments from the annotators explaining their per-competence scores. They are included in our dataset.

SOURCE_B_DESC = """
Source B is very similar to Source A: a new prompt and supporting texts are made available every month along with the graded essays submitted in the previous month.
We downloaded HTML sources from 7,700 essays from May 2009 to May 2023. Essays released prior to June 2016 were graded on a five-point scale and consequently discarded.
This resulted in a corpus of approx. 3,200 graded essays on 83 different prompts.

Although in principle, Source B also provides supporting texts for students, none were available at the time the data was downloaded.
To mitigate this, we extracted supporting texts from the Essay-Br corpus, whenever possible, by manually matching prompts between the two corpora.
We ended up with approx. 1,000 essays containing both prompt and supporting texts, and approx. 2,200 essays containing only the respective prompt.
