# Subjectivity

This dataset is a Hugging Face Hub packaging of the NLTK `subjectivity` corpus,
which mirrors the Subjectivity Dataset v1.0 released by Bo Pang and Lillian Lee.

## Contents

- `train`: 10,000 text snippets
- Labels:
- `0` / `objective`: sentences from IMDb plot summaries
- `1` / `subjective`: snippets from Rotten Tomatoes reviews

## Notes

- The original corpus does not define official train/validation/test splits, so
this packaging preserves the full dataset as a single `train` split.
- Text is already lower-cased in the upstream corpus.

# 主观性数据集（Subjectivity）

本数据集是针对自然语言工具包（Natural Language Toolkit，NLTK）的`subjectivity`语料库的拥抱脸Hub（Hugging Face Hub）封装版本，其复刻了由Bo Pang与Lillian Lee发布的1.0版主观性数据集（Subjectivity Dataset v1.0）。

## 数据集内容

- 训练集（train）：10000条文本片段
- 标签说明：
- `0` / 客观（objective）：源自互联网电影数据库（Internet Movie Database, IMDb）剧情简介的语句
- `1` / 主观（subjective）：源自烂番茄（Rotten Tomatoes）影评的文本片段

## 注意事项

- 原始语料库未定义官方的训练、验证、测试拆分方式，因此本封装将完整数据集统一置于单个`train`拆分集中。
- 上游语料库中的文本已全部转为小写形式。

## 数据源
