 ## Dataset Summary
 
 This is the translated version of the [PIQA](https://huggingface.co/datasets/ybisk/piqa) LLM evaluation dataset. The dataset was translated using a new method called Expressive Semantic Translation (EST), which combines Google Translation with LLM-based rewriting. PIQA introduces the task of physical commonsense reasoning and provides a corresponding benchmark for understanding physical interactions in everyday situations. It focuses on atypical solutions to practical problems, inspired by instructional guides from instructables.com, and aims to tackle one of the major challenges in AI: understanding and reasoning about physical commonsense knowledge.
