To illustrate the above title.
Suppose you have a pdf document, which is basically scanned from hardcopy, now there are set of fixed questions to answer from the document itself. For an example a document contains a contract of land, now the set of fixed questions be "who is the seller?" "what is price of the asset? ", document has referred to this answers probably 2-3 times, as a human it's a simple task.
How to automate this?
