功能概述
该算子用于过滤特殊字符比例在指定范围内的文本样本。
核心参数
| 参数 | 类型 | 必填 | 默认值 | 说明 |
|---|---|---|---|---|
| input_path | string | 是 | - | 输入数据文件路径 (JSON/JSONL格式) |
| output_path | string | 是 | - | 输出数据文件路径 (JSONL格式) |
| min_ratio | float | 否 | 0.0 | 最小特殊字符比例 |
| max_ratio | float | 否 | 0.25 | 最大特殊字符比例 |
| batch_size | int | 否 | 1 | 批处理大小 |
| num_proc | int | 否 | 1 | 并行处理的进程数 |
| text_key | string | 否 | text | 要操作的文本字段名 |
输入数据格式
输入文件应为 JSON 或 JSONL 格式,每行包含一个样本,样本需包含 text_key 指定的字段(默认 text):
{"<text_key>": "这是一段包含特殊字符的文本内容"}
输出数据格式
输出为 JSONL 格式,每行一个符合条件的样本,仅包含 text 字段。
使用示例
命令行调用
python scripts/run_special_characters_filter.py \
--input_path /path/to/input.jsonl \
--output_path /path/to/output.jsonl \
--min_ratio 0.0 \
--max_ratio 0.25
参数说明
--input_path: 输入文件路径--output_path: 输出文件路径--min_ratio: 最小特殊字符比例(默认0.0)--max_ratio: 最大特殊字符比例(默认0.25)--batch_size: 批处理大小(默认1)--num_proc: 并行进程数,默认1--text_key: 要操作的文本字段名(默认text)
注意事项
- 特殊字符包括:,。、„""«»1」「《》´∶:?!"()";–—.~'…━〈〉【】%► 等
- 比例计算方式:特殊字符数 / 总字符数
- 处理大量数据时可适当增加 batch_size 和 num_proc 提高效率
