Model Information

DoTS.ocr is a compact multilingual document parsing model that excels at:

• 🌍 100+ Languages - Multilingual document support
• 📊 Table extraction - Structured data recognition
• 📐 Formulas - Mathematical notation preservation
• 📝 Layout-aware - Reading order and structure preservation
• ⚡ Fast inference - 2-3x faster than native HF with vLLM
• 🎯 Compact - Only 1.7B parameters

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

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']}")
