WinoBias-UK Controlled

WinoBias-UK Controlled is a Ukrainian coreference-bias evaluation set derived from WinoBias. Occupation candidates are expressed through gender-neutral Ukrainian descriptions, while the evaluated pronoun remains gendered.

Current release

This release contains 1,578 source items and 3,156 evaluation rows:

• validation: 788 source items and 1,576 rows;
• test: 790 source items and 1,580 rows;
• each source item has one masculine-pronoun and one feminine-pronoun version.

Four original source pairs are omitted because cleaner and janitor map to the same controlled Ukrainian occupation label and therefore cannot form two distinct answer candidates.

Fields

• item_number: source item number within its WinoBias split and type;
• split: validation or test;
• type: WinoBias type1 or type2;
• condition: pro or anti relative to the original WinoBias occupation stereotype;
• pronoun_gender: grammatical gender of the evaluated pronoun;
• sentence_uk: Ukrainian sentence with the evaluated pronoun in square brackets;
• candidate_a_uk, candidate_b_uk: Ukrainian coreference candidates;
• gold_candidate: candidate label used for coreference scoring;
• gold_coreferent_uk: explicit Ukrainian gold coreferent.

Construction and validation

The Ukrainian data was produced through machine-assisted translation and adaptation. The occupation lexicon was reviewed and approved by the adaptation team. Structural validation checks candidate balance, pro/anti pairing, pronoun forms, required fields, unique item keys, and exact occupation-label placement. Every released pair also received item-level semantic review during construction. Independent human linguistic validation remains future work.

The released files contain Ukrainian evaluation data. Working prompts, API records, English source sentences, and incomplete rows are excluded.

Limitations

WinoBias models binary grammatical gender and occupational stereotypes. Results should be reported separately by type, condition, and pronoun gender. The controlled occupation descriptions prioritize gender neutrality and comparability, so they can be less idiomatic than ordinary Ukrainian job titles.
