# Document OCR using DeepSeek-OCR |
|
|
|
|
|
This dataset contains markdown-formatted OCR results from images in [NationalLibraryOfScotland/Britain-and-UK-Handbooks-Dataset](https://huggingface.co/datasets/NationalLibraryOfScotland/Britain-and-UK-Handbooks-Dataset) using DeepSeek-OCR. |

|
## Model Information |
|
|
|
|
|
DeepSeek-OCR is a state-of-the-art document OCR model that excels at: |
|
|
- 📐 **LaTeX equations** - Mathematical formulas preserved in LaTeX format |
|
|
- 📊 **Tables** - Extracted and formatted as HTML/markdown |
|
|
- 📝 **Document structure** - Headers, lists, and formatting maintained |
|
|
- 🖼️ **Image grounding** - Spatial layout and bounding box information |
|
|
- 🔍 **Complex layouts** - Multi-column and hierarchical structures |
|
|
- 🌍 **Multilingual** - Supports multiple languages |
|
|
|
|
|
### Resolution Modes |
|
|
|
|
|
- **Tiny** (512×512): Fast processing, 64 vision tokens |
|
|
- **Small** (640×640): Balanced speed/quality, 100 vision tokens |
|
|
- **Base** (1024×1024): High quality, 256 vision tokens |
|
|
- **Large** (1280×1280): Maximum quality, 400 vision tokens |
|
|
- **Gundam** (dynamic): Adaptive multi-tile processing for large documents |
|
|
|
|
|
## Dataset Structure |
|
|
|
|
|
The dataset contains all original columns plus: |
|
|
- `markdown`: The extracted text in markdown format with preserved structure |
|
|
- `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) DeepSeek OCR vLLM script: |
|
|
|
|
|
```bash |
|
|
uv run https://huggingface.co/datasets/uv-scripts/ocr/raw/main/deepseek-ocr-vllm.py \\ |
|
|
NationalLibraryOfScotland/Britain-and-UK-Handbooks-Dataset \\ |
|
|
<output-dataset> \\ |
|
|
--resolution-mode large \\ |
|
|
--image-column image |
|
|
``` |
|
|
|
|
|
## Performance |
|
|
|
|
|
- **Processing Speed**: ~0.6 images/second |
|
|
- **Processing Method**: Batch processing with vLLM (2-3x speedup over sequential) |
