AZURE/AWS based project

by learning to recognize the content of documents we need to sort them in groups (for example supplier's invoices or dispatch notes , receipts...) .
The system should be requested to import automatically from specific folder the documents subject to OCR + AI analysis. The import folder should be always recalled when the procedure starts .
After recognised (and confirmed by the user when a certain value of certainity is not matched) we need to extract from the groups the values of specified fields (and learned) on specific files (excel file ) .
