I need to do a comparative review of research articles available in pdf on defined parameters . So the data and text needs to be extracted, processed and organized using NLP / NLG tools

I need someone to do a comprehensive comparison between 60 research articles available in pdf format. My intention is to have the output in a Word document that contains the data and text extracted, processed and organized using NLP / NLG tools. I already have established parameters for the comparison, so this should help guide the process. The results should be comprehensive and include all the relevant information found in these documents.
