SIMORD

HuggingFace re-upload of the SIMORD dataset, a medical order extraction benchmark based on doctor-patient conversations, with corrections to data splits and all text transcripts now included by default. If used, please cite the original authors using the citation below.

Dataset Description

The dataset contains three splits (with their corresponding original SIMORD files):

1. train (from train.json): examples for in-context learning or fine-tuning.
2. test1 (from dev.json): test set used for the EMNLP 2025 industry track paper.
3. test2 (from test.json): test set for MEDIQA-OE shared task of ClinicalNLP 2025.

With the following distribution

Split	Original	New	Change
train	63	81	+18
test1	100	90	-10
test2	100	92	-8
TOTAL	263	263	-

Note: Both the original SIMORD dataset and this upload use the split name test1 instead of dev/validation (even though the file is dev.json) and test2 instead of test (even though the file is test.json), since both were used as test sets.

Dataset Changes

The SIMORD dataset is derived from both ACI-Bench and PriMock57.

While PriMock57 doesn't contain any explicit data splits, ACI-Bench contains five splits: train, valid, test1, test2, and test3. As discussed in an open HF issue, these splits were not respected when being merged into SIMORD.

For example, SIMORD's test.json contains an ACI-Bench train sample:

"id": "acibench_D2N036_aci_train"

The official SIMORD HF upload contains three data files that are mapped to the following splits

SIMORD File	Mapped Split	Total	Train	Valid/Dev	Test1	Test2	Test3	PriMock57
train.json	train	63	15	8	8	10	8	14
dev.json	test1	100	27	3	20	14	13	23
test.json	test2	100	25	9	11	16	19	20

This updated version of SIMORD reallocates samples using the following logic:

• New train = old train (train+PriMock57 samples) + old test1 (train samples) + old test2 (train samples)
• New test1 = old test1 (non-train samples) + half of old train (non-train, non-PriMock57 samples)
• New test2 = old test2 (non-train samples) + half of old train (non-train, non-PriMock57 samples)

In other words:

• Samples with _train suffix are moved to train, regardless of which original file they came from
• PriMock57 samples stay in their original splits, since PriMock57 has no explicit data splits
• Non-train samples in the original test1 and test2 splits stay where they are
• Non-train, non-PriMock57 samples that were misplaced in the original train split are evenly distributed between test1 and test2

After reallocation, the new splits contain the following counts:

New Split	Total	Train	Valid/Dev	Test1	Test2	Test3	PriMock57
train	81	67	0	0	0	0	14
test1	90	0	7	24	19	17	23
test2	92	0	13	15	21	23	20
