Tools and Web services

Semi-automatic annotation tool

A semi-automatic text annotation tool is developped by the project. It takes PDF documents as input and processes them automatically by applying the three following steps:

  • layout detection,
  • optical characters recognition (with PERO OCR),
  • named entities recognition (fine-tuned CamemBERT model).

Users can then check and manually correct each automatically detected and processed text section.
