BalkanBench SuperGLUE - Montenegrin

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

This is the Montenegrin SuperGLUE released preview track of BalkanBench v0.1, covering the same 5 ranked tasks as the Croatian preview. Same scoring contract as Serbian (the official frozen track), same private test labels, no WSC adaptation yet.

What's inside

5 task configs, full train + validation + public test splits (train and validation labelled here; the test split lives only in the gated sibling repo, see below):

Config	What it tests	Train	Validation	Test
boolq	Yes/no question answering over passages	9,427	3,270	3,245
cb	3-way textual entailment (entail / contradict / neutral)	250	56	250
copa	Causal reasoning between two alternatives	400	100	500
multirc	Multi-sentence reading comprehension (multiple correct)	27,243	4,848	9,693
rte	Binary textual entailment	2,490	277	3,000
TOTAL		39,810	8,551	16,688

Total: 65,049 items. WSC and the AX-b/AX-g diagnostics are Serbian-only in v0.1.

Test split is gated

The test split for every config lives only in the gated sibling repo (both inputs and labels): permitt/superglue-mne-private, and are accessed only by the official scoring pipeline. To get a leaderboard score, generate predictions on the public test inputs with balkanbench predict, then submit through the submission flow.

Loading

from datasets import load_dataset

boolq = load_dataset("permitt/superglue-mne", "boolq")
print(boolq["train"][0])

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

Pin a revision for reproducible runs:

load_dataset("permitt/superglue-mne", "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 cb:

{
    "idx": 0,
    "premise": "Poli je morala brzo da razmisli. ...",
    "hypothesis": "Poli nije bila iskusna okeanska jedriličarka.",
    "label": 0,  # 0=entailment, 1=contradiction, 2=neutral
}

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

Methodology

• Translation: original SuperGLUE English -> Montenegrin via translation + human verification by native speakers.
• Frozen splits: train/validation/test row counts and IDs pinned at tag v0.1.0-data.
• Test labels stay private: see the gated sibling repo above.
