You can send document pages for human review by providing an image URL and an ALTO XML URL. This creates a Label Studio task with pre-annotations, allowing reviewers to correct AI transcriptions and segmentations efficiently.

Yes, you can send image-only document pages to Label Studio for annotation from scratch. Providing just the image URL creates a blank canvas task, allowing human reviewers to manually annotate the document page without any pre-existing AI transcriptions.

ALTO XML stores pre-annotated transcription and segmentation data for document pages. Sending this format to Label Studio overlays existing AI-generated text on the image, enabling human reviewers to verify and correct the output efficiently.

Yes, the workflow supports correcting both segmentation boundaries and transcription text. When document pages are sent to Label Studio using ALTO XML, reviewers can adjust layout segmentation and corresponding text during the quality assurance process.

Use pre-annotated tasks with ALTO XML when you have existing AI transcriptions needing human correction. Use blank image tasks when you want reviewers to manually transcribe and segment document pages from scratch without initial AI-generated content.
