# InfiMM-Math Contents

The dataset is structured as follows:

```
{
  "URL": ...,  # document url.
  "text_list": ...,  # extracted text from document, None means a image.
  "image_list": ...,  # extracted image urls from document, None means text.
  "metadata": ...,  # JSON containing information from the extraction process.
}
```

## Interleaved Text and Images

The `text_list` and `image_list` are designed to be parallel lists that together represent the sequential content of the document. The interleaving works as follows:

	•	If an element in `text_list` is a string (i.e., not None), the corresponding element in image_list is None, indicating that this position in the document contains text.
	•	If an element in `text_list` is None, the corresponding element in image_list contains an image URL, indicating that this position in the document contains an image.

This structure preserves the original order of text and images, allowing for accurate reconstruction of the document’s content flow.
