OCR with AI (intelligend data processing)

Job ID: 35389087

Budget: $500 – $1,000 USD

I already have a python software source-code that converts PDF files into structured Json files.
This is done using OCR and YOLOv5.
The PDF files are supplier invoices. These invoices consist of a header, x items and a footer. There are a subset of predfinded variables (like customer_number, invoice_number, ...) to extract from pdf.

I now need the following adjustments:
1.) the tool needs to be improved. Because it does not recognize the data correctly for the positions.
2.) I need a simple graphical user interface to learn (train) more PDF files. I need a generic solution for this. Today's solution is not generic, but trained and coded for 3 different PDF formats.
3.) the learned models should learn from each other. This means that the tool should learn automatically when new PDF files are trained. If a new format comes along, it should also recognize it as best as possible without necessarily having to train it.

Now I am asking for offers to improve the tool and bring in these 3 points.

These are the requirements of the python tool that must be installed for the tool to run:
