longmino_filtered
本目录为 Dolma 3 Longmino Pool 数据经简单过滤后的分片，按子集分子文件夹存放。数据无需转换为 Parquet 即可配合 Hugging Face datasets 使用（见 scripts/load_longmino_example.py）。
数据来源与处理
- 上游数据集：allenai/dolma3_longmino_pool（Dolma 3 Longmino Pool，非混合后的训练 mix；详见该数据集说明）。
- 本目录：仅对上游数据做了简单过滤得到的副本文档集合，不是 Ai2 官方发行物，也不代表上游数据的完整或最新版本。
- 用途说明：以自用（个人研究/训练）为主，无面向公众的推广义务；若他人获取副本，仍应遵守下方许可与上游要求。
许可
遵循上游 Open Data Commons Attribution License v1.0（ODC-By） 及 dolma3_longmino_pool 页面中的许可与使用说明；引用与责任边界请以 Ai2 / 官方数据集页面 为准。详细条款见上游 Dataset Card 中的 Licensing Information。
目录结构
| 子目录 | 说明 |
|---|---|
2e15/ |
length 元数据中为 2e15 档位的样本 shard |
2e16/ |
同上，2e16 |
2e17/ |
同上，2e17 |
8k_32k/ |
8k–32k 相关档位 |
synth_cwe/ |
含合成 CWE 相关元数据 |
synth_rex/ |
含合成 REX 相关 shard |
每个子目录下为多个 gzip 压缩的 JSONL 文件：longmino_<子集名>-NNNN.jsonl.gz。
注意：少数分片文件扩展名为 .json.gz，内容为多行 JSON（与 JSONL 相同读法），不是「单个 JSON 数组」；加载时需与 .jsonl.gz 一并纳入 data_files（示例脚本已处理）。
单条样本 schema（顶层）
每条 JSON 为一行，主要字段：
text(string)：正文。id(string)：文档标识。source、added、created：string。metadata(object)：嵌套元数据，常见键包括Source-Url、length、provenance、len_cl100k_base等；不同子集可能包含额外键（如synth_cwe）。
完整字段以实际数据为准；若在不同 shard 间类型不一致，可在 load_dataset 时传入 features= 或先将 metadata 序列化为字符串再训练。
依赖
pip install datasets
（若仅做分片校验，也可只用标准库读 gzip 首行。）
示例
# 列出某子集分片并查看第一个分片首条样本的顶层字段与 text 前缀
python scripts/load_longmino_example.py --root . --subset synth_cwe --peek
# 流式读取前几项（省内存）
python scripts/load_longmino_example.py --root . --subset 2e15 --streaming --max-items 3
将 --root 换成本目录的绝对路径亦可。
与 Hugging Face Hub
若将本目录同步到个人 Hub 仓库（例如 longmino_256k_filtered），请在 Dataset Card 中保留对上述上游链接与 ODC-By 的说明；本 README 可作为草稿。若仅在本机或共享盘使用，可以不建 Hub 数据集仓库。
