### Dataset Structure

| Column                        | Type  | Description                                                       |

| `Review`                      | `str` | The raw restaurant review.                                        |
| `<Aspect#Category>` (12 cols) | `int` | Polarity indicator (0=absent, 1=positive, 2=negative, 3=neutral). |
| `type`                        | `str` | Split: `train` / `validation` / `test`.                           |
| `dataset`                     | `str` | Always `VLSP2018-ABSA-Restaurant`.                                |

The 12 aspect–category columns:

```
AMBIENCE#GENERAL, DRINKS#PRICES, …, SERVICE#GENERAL
```


### Usage

```python
from datasets import load_dataset

ds = load_dataset("visolex/vlsp2018-absa-restaurant")

train = ds.filter(lambda ex: ex["type"] == "train")
val   = ds.filter(lambda ex: ex["type"] == "dev")
test  = ds.filter(lambda ex: ex["type"] == "test")

print(train.features)
```
