We have a set of PDFs with the different types of documents from the various companies. The goal: to predict which of them contain some important attributes (for example, document number, customer name) and extract them. May be also predict the type of document. Some of them already marked for the training.
How to do that better theoretically? Use transformation PDF to text and then work with it as with text? Or first split page layout to the squares and predict, that it contains key attribute before?
Thank you for any help!
