### Dataset Summary

Large Movie Review Dataset.
This is a dataset for binary sentiment classification containing substantially more data than previous benchmark datasets. We provide a set of 25,000 highly polar movie reviews for training, and 25,000 for testing. There is additional unlabeled data for use as well.

### Supported Tasks and Leaderboards

[More Information Needed](https://github.com/huggingface/datasets/blob/master/CONTRIBUTING.md#how-to-contribute-to-the-dataset-cards)

### Languages

## Dataset Structure

### Data Instances

#### plain_text

- **Size of downloaded dataset files:** 84.13 MB
- **Size of the generated dataset:** 133.23 MB
- **Total amount of disk used:** 217.35 MB

An example of 'train' looks as follows.
```
{
"label": 0,
"text": "Goodbye world2\n"
}
```

### Data Fields

The data fields are the same among all splits.

#### plain_text
- `text`: a `string` feature.
- `label`: a classification label, with possible values including `neg` (0), `pos` (1).

### Data Splits

| name |train|unsupervised|test |
|----------|----:|-----------:|----:|
