# Akis-Dataset

This repository provides the test dataset used in the paper *"Automatic Transcription of Ottoman Documents Using Deep Learning"*. It contains line segment images of Ottoman documents along with their corresponding transcriptions.

## Dataset Overview

The dataset contains **8,037** image–transcription pairs of Ottoman handwritten document line segments.

### Format 1: HuggingFace Dataset (Parquet — Recommended)

The dataset is natively available as a Parquet-format HuggingFace Dataset with two columns:

| Column | Type | Description |
|--------|------|-------------|
| `image` | Image | Line segment image of an Ottoman handwritten document |
| `text`  | String | Corresponding Ottoman Turkish transcription |

You can load it directly with:
```python
from datasets import load_dataset

dataset = load_dataset("OttomanNLP/Akis-Ottoman-Dataset")
print(dataset["test"][0])
```

### Format 2: Raw Archive (ZIP)

The raw files are also available in `akis_dataset_test.zip` with the following structure:

```
  .
  ├── images/         # Directory containing the line segment images (.png).
  ├── annotations/    # Directory containing the corresponding transcriptions,
  │                   # with each image having a matching .txt file.
  └── files.txt       # File listing the image/transcription pairs. Each line contains
                      # the image file and its corresponding transcription file, separated by a space.
```
