lowinfo_filter
Documents低信息量过滤工具。读取结构化数据文件,对指定文本列同时校验字符总数与行数是否落在阈值区间内,输出过滤后的合规行。 当用户提到低信息量过滤、字符数筛选、短文本过滤、超长文本过滤、行数过滤、信息量阈值等需求时使用此skill。 即使用户没有明确说出"低信息量",只要任务涉及同时按字符数和行数两个维度过滤文本行,就应该使用此skill。 不负责按单词数过滤(用words_num_filter)、按token数过滤(用token_num_filter)、按最长单行长度过滤(用maximum_line_length_filter)或按平均行长度过滤(用average_line_length_filter)。与这些skill的关键区别在于:本skill同时校验字符总数与行数两个维度,且原生支持CSV/TSV/Excel多列输入、不依赖data_juicer。

lowinfo_filter 低信息量过滤
功能概述
- 按字符数/行数上下限过滤低/高信息样本。
- 支持多列检测,默认所有字符串列。
参数说明
| 参数 | 必填 | 默认值 | 说明 |
|---|---|---|---|
--input_path | 是 | 输入文件路径(支持CSV/TSV/Excel等) | |
--output_path | 是 | 输出文件路径(过滤后的文件) | |
--text_columns | 否 | 需检测的文本列,逗号分隔;不填默认全部字符串列 | |
--min_chars | 否 | 最小字符数,默认 10 | |
--max_chars | 否 | 最大字符数(0 表示不限),默认 2000 | |
--min_lines | 否 | 最小行数,默认 1 | |
--max_lines | 否 | 最大行数(0 表示不限),默认 200 |
使用方法
python scripts/lowinfo_filter.py \
--input_path <输入文件> \
--output_path <输出文件> \
[--text_columns col1,col2] \
[--min_chars 10] [--max_chars 2000] \
[--min_lines 1] [--max_lines 200]
输出说明
- 仅保留满足阈值的行;过滤掉的行不输出。
- 控制台提示输出行数与原始行数。
注意事项
- 合理设置 min/max,避免过度过滤。
- 若需保留原因,可调整脚本保留 filter_reason 列(当前实现剔除)。
