How create dataset format FUNSD ?

example format:

        {
        "form": [
        {
            "id": 0,
            "text": "Registration No.",
            "box": [94,169,191,186],
            "linking": [
                [0,1]
            ],
            "label": "question",
            "words": [
                {
                    "text": "Registration",
                    "box": [94,169,168,186]
                },
                {
                    "text": "No.",
                    "box": [170,169,191,183]
                }
            ]
        },
        {
            "id": 1,
            "text": "533",
            "box": [209,169,236,182],
            "label": "answer",
            "words": [
                {
                    "box": [209,169,236,182
                    ],
                    "text": "533"
                }
            ],
            "linking": [
                [0,1]
            ]
        }
    ]
    }

I am also having to label something like this.

The labeling tool should use auto OCR so that it becomes easy to work for these cases.

They added a new feature for this https://github.com/heartexlabs/label-studio-ml-backend/tree/master/label_studio_ml/examples/tesseract

Check this PR: https://github.com/heartexlabs/label-studio-converter/pull/127. Now you can export to FUNSD using this script.

Unfortunately we can’t make 100% compatible conversion to FUNSD format, because it has root bboxes and words bboxes and LS doesn’t build root bboxes automatically. So, this converter creates one root bbox with one word inside of it.
