Dataset Description

This dataset contains training data for DotsOCR to convert document images directly to markdown format.

Training Objective

The model learns to:

• Convert document images to clean markdown format
• Preserve document structure and hierarchy
• Extract all text content accurately
• Use appropriate markdown formatting for different content types

Dataset Structure

• Training samples: 798
• Validation samples: 200
• Total samples: 998

Files

• data/dotsocr_markdown_dataset_train.json: Training data in conversation format
• data/dotsocr_markdown_dataset_val.json: Validation data in conversation format
• images/: Directory containing all referenced images

Data Format

Each sample follows this conversation format:

{
  "conversations": [
    {
      "from": "user",
      "value": "<|imgpad|>images/example.jpg<|/imgpad|>\nPlease convert this document image to markdown format..."
    },
    {
      "from": "assistant",
      "value": "# Document Title\n\n## Section Header\n\nContent text here..."
    }
  ]
}

Training Prompt

The training uses this prompt to teach the model markdown conversion:

Convert this document image to markdown format. Extract and structure the text content as follows:

- Headers and titles as plain text on separate lines
- Body text as plain text paragraphs
- Lists using * for bullet points
- Tables using HTML table format: <table><thead><tr><th>...</th></tr></thead><tbody><tr><td>...</td></tr></tbody></table>
- Preserve the original reading order and document structure
- Extract all visible text exactly as it appears

Output the content in markdown format with HTML tables for tabular data.

Usage

This dataset is designed to train DotsOCR models for direct image-to-markdown conversion tasks. The model learns to:

1. Analyze document images
2. Extract text content in reading order
3. Apply appropriate markdown formatting
4. Output clean, structured markdown
