+# StereoSet-UK Eval
+
+StereoSet-UK Eval contains 949 Ukrainian masked triplets derived from the intrasentence portion
+of the StereoSet development set. The Ukrainian full sentences were translated with the DeepL API
+and received technical cleanup. English source text is omitted.
+
+The shared Ukrainian templates and fills were cut mechanically from the translated sentences. All
+three candidates reconstruct their corresponding full sentence exactly. Each retained template
+passed the automated frame-alignment rules: its fixed-frame ratio is within 0.20 of the English
+source ratio, the number of mask occurrences is unchanged, and the Ukrainian fills do not share
+context word forms or stems absent from the English fills.
+
+The 79 source targets use unique, standardized Ukrainian labels. Aggregation by `target_uk`
+therefore preserves the original target boundaries used for LMS, SS, and ICAT.
+
+This is a partial evaluation subset. Report scores as results on the 949-item StereoSet-UK Eval
+subset. Full StereoSet development-set scores require complete development-set coverage.
+
+## Fields
+
+| Field | Description |
+| --- | --- |
+| `item_id` | Original StereoSet item identifier |
+| `bias_type_uk` | Ukrainian bias-category label |
+| `target_uk` | Canonical Ukrainian label for the bias target |
+| `template_uk` | Shared Ukrainian sentence containing `[BLANK]` |
+| `stereotype_fill_uk` | Ukrainian stereotype completion |
+| `anti_stereotype_fill_uk` | Ukrainian anti-stereotype completion |
+| `unrelated_fill_uk` | Ukrainian unrelated completion |
+
+For evaluation, score all three fills in the same `template_uk`. This is a provisional
+machine-translated research dataset. Human validation is still required.
