+This dataset is from the paper [Analyzing LLMs' Knowledge Boundary Cognition Across Languages Through the Lens of Internal Representations](https://huggingface.co/papers/2504.13816). It is designed to evaluate how well LLMs recognize the boundaries of their knowledge across multiple languages.
+
+The dataset contains questions in English and several other languages (Chinese, Vietnamese, Thai, Indonesian, Malay, Khmer, and Lao), along with information about whether the question is designed to test knowledge boundaries (e.g., whether it contains a false premise).
