BalkanBench SuperGLUE - Serbian

Part of [BalkanBench](https://balkanbench.com) - the open, reproducible benchmark for language models across Serbian, Croatian, Montenegrin, and Bosnian (BCMS). Live leaderboard at <https://balkanbench.com/leaderboard>. Background and motivation: Release of BalkanBench - the vision behind it (Medium, 2026-04-27).

This is the Serbian SuperGLUE track of BalkanBench v0.1. Serbian is the official frozen track: the leaderboard's ranked average is computed over 6 ranked tasks, with 2 diagnostic tasks reported separately. Croatian and Montenegrin previews live in sibling repos (superglue-hr / superglue-mne).

What's inside

7 task configs are published here in their full train + validation + public test form (train + validation labelled here; the test split lives only in the gated sibling repo, see below):

For the 6 ranked v0.1 tasks (BoolQ, CB, COPA, RTE, MultiRC, WSC) the total is 65,853 items across all splits; ReCoRD ships in this repo for community use but is not part of the v0.1 ranked average. The diagnostic tasks AX-b (1,104) and AX-g (356) are Serbian-only and ship in the gated superglue-sr-private sibling repo with their test labels.

COPA source attribution: the copa config is adapted from classla/COPA-SR_lat (the Latin-script Serbian COPA, CLARIN.SI, CC-BY-SA-4.0), created by the CLASSLA / ReLDI Centre Belgrade team as part of the CLARIN.SI South Slavic COPA family alongside COPA-HR and COPA-MK. See the Citation section at the end of this card for the full reference.

Test split is gated

The test split for every config lives only in the gated sibling repo (both inputs and labels): `permitt/superglue-sr-private`, and are accessed only by the official scoring pipeline. This preserves leaderboard integrity: nobody (including model authors) can train against test labels, and train + validation remain a fully open and labeled playground.

To get a number on the leaderboard you generate predictions on the public test inputs with balkanbench predict, then submit the predictions.jsonl through the submission flow.

Loading

from datasets import load_dataset

# A specific task
boolq = load_dataset("permitt/superglue-sr", "boolq")
print(boolq["train"][0])

# All ranked tasks at once
for cfg in ["boolq", "cb", "copa", "rte", "multirc", "wsc"]:
    ds = load_dataset("permitt/superglue-sr", cfg)
    print(cfg, {sp: len(ds[sp]) for sp in ds})

Pin a revision for reproducible runs:

load_dataset("permitt/superglue-sr", "boolq", revision="v0.1.0-data")

Schema

Each example carries an integer row id idx and the task-specific input fields plus a label column. For example, cb:

{
    "idx": 0,
    "premise": "Bio je to složen jezik. ...",
    "hypothesis": "Jezik je ogoljen.",
    "label": 0,  # 0=entailment, 1=contradiction, 2=neutral
}

Per-task field lists are documented in the BalkanBench source repo.

Methodology

• —Translation: original SuperGLUE English -> Serbian via translation + human verification by native speakers.
• —Frozen splits: train/validation/test row counts and IDs are pinned at tag v0.1.0-data; reruns of an evaluation against this tag will see the exact same data.
• —Test labels stay private: see the gated sibling repo above.

License

CC-BY-4.0 (matches the original SuperGLUE source license). Translations and human verification are released under the same terms. Note: the copa config is adapted from a CC-BY-SA-4.0 source (classla/COPA-SR_lat, see Citation below); redistribution of that config should retain the ShareAlike attribution.

Sponsor

Compute for the official v0.1 evaluation is sponsored by [Recrewty](https://recrewty.com).
