US K–12 Schools — Open Dataset for the AI Era
One encyclopedic paragraph for every one of the 122,675 K–12 schools in the United
States, ready to use as pretraining text.
Ask a language model about a large suburban high school and it will answer. Ask it about
the K–8 school in a rural county of 4,000 people and it has nothing to say — because
nothing about that school was ever written down on the open web. Only about 12% of
American schools have a Wikipedia article at all, and… See the full description on the dataset page: https://huggingface.co/datasets/SchoolData/us-k12-schools.China-K12-STEM-10K-CoT-Reasoning

distilled_s0_e20000.jsonl包含这个数据集的数据，下面介绍数据标签：
idx：索引号（0~19999）
question：原数据集中的problem标签，是一个可能包含多个子问题的数学问题字符串
gt_cot：愿数据集中的solution标签，是经过GPT-4o整理的答案字符串
pred_cot：根据question标签，模型DeepSeek-R1-Distill-Qwen-32B的回答字符串
pred_cot_token_len：pred_cot标签下的字符串转化成token之后的长度（不包含最前面的<think>\n部分，这个在生成的时候是在prompt里面，我后来加到这里了）
message：根据question标签和pred_cot标签，构造的问题-回答数据对
