# Document OCR using HunyuanOCR
This dataset contains OCR results from images in [NationalLibraryOfScotland/Scottish-School-Exam-Papers](https://huggingface.co/datasets/NationalLibraryOfScotland/Scottish-School-Exam-Papers) using HunyuanOCR, a lightweight 1B VLM from Tencent.
## Processing Details
- **Source Dataset**: [NationalLibraryOfScotland/Scottish-School-Exam-Papers](https://huggingface.co/datasets/NationalLibraryOfScotland/Scottish-School-Exam-Papers)
- **Model**: [tencent/HunyuanOCR](https://huggingface.co/tencent/HunyuanOCR)
- **Number of Samples**: 100
- **Processing Time**: 9.8 min
- **Processing Date**: 2025-11-25 16:15 UTC
### Configuration
- **Image Column**: `image`
- **Output Column**: `markdown`
- **Dataset Split**: `train`
- **Batch Size**: 1
- **Prompt Mode**: parse-document
- **Prompt Language**: English
- **Max Model Length**: 16,384 tokens
- **Max Output Tokens**: 16,384
- **GPU Memory Utilization**: 80.0%
## Model Information
HunyuanOCR is a lightweight 1B VLM that excels at:
- 📝 **Document Parsing** - Full markdown extraction with reading order
- 📊 **Table Extraction** - HTML format tables
- 📐 **Formula Recognition** - LaTeX format formulas
- 📈 **Chart Parsing** - Mermaid/Markdown format
- 📍 **Text Spotting** - Detection with coordinates
- 🔍 **Information Extraction** - Key-value, fields, subtitles
- 🌐 **Translation** - Multilingual photo translation
## Prompt Modes Available
- `parse-document` - Full document parsing (default)
- `parse-formula` - LaTeX formula extraction
- `parse-table` - HTML table extraction
- `parse-chart` - Chart/flowchart parsing
- `spot` - Text detection with coordinates
- `extract-key` - Extract specific key value
- `extract-fields` - Extract multiple fields as JSON
- `extract-subtitles` - Subtitle extraction
- `translate` - Document translation
## Dataset Structure
The dataset contains all original columns plus:
- `markdown`: The extracted text in markdown format
- `inference_info`: JSON list tracking all OCR models applied to this dataset
## Usage
```python
from datasets import load_dataset
import json
# Load the dataset
dataset = load_dataset("{output_dataset_id}", split="train")
# Access the markdown text
for example in dataset:
print(example["markdown"])
break
# View all OCR models applied to this dataset
inference_info = json.loads(dataset[0]["inference_info"])
for info in inference_info:
print(f"Column: {info['column_name']} - Model: {info['model_id']}")
```
## Reproduction
This dataset was generated using the [uv-scripts/ocr](https://huggingface.co/datasets/uv-scripts/ocr) HunyuanOCR script:
```bash
uv run https://huggingface.co/datasets/uv-scripts/ocr/raw/main/hunyuan-ocr.py \
NationalLibraryOfScotland/Scottish-School-Exam-Papers \
<output-dataset> \
--image-column image \
--batch-size 1 \
--prompt-mode parse-document \
--max-model-len 16384 \
--max-tokens 16384 \
--gpu-memory-utilization 0.8
```
