BBH-PT (Big-Bench Hard)

Portuguese machine translation of BIG-Bench Hard, a challenging subset of the BIG-Bench benchmark covering diverse reasoning tasks.

Translated using a Finetuned GemmaX2-9B for pt-PT with rule-based adaptations.

Note: Some tasks (e.g., hyperbaton) are not translated as they do not transfer meaningfully to Portuguese.

Original Dataset: https://github.com/suzgunmirac/BIG-Bench-Hard

Note: This dataset is machine translated and may contain translation errors or artifacts.

This dataset is provided as part of the AMALIA project and is included in AMALIA-Bench, a comprehensive benchmark suite for evaluating large language models on European Portuguese.
