Keywords based on pdf files

Hello everyone,

I would like to know if there is a way to automatically detect the keywords from one text based on PDF attachment that I have.

For example, I have some texts that have no keywords placed in the reference view. (see

). However, I have the corresponding .pdf file attached, as you can also see link above. What I want is to add the keywords from the text - in this case, the keywords are Business Improvement Districts; neoliberalism; urban revitalization; Istanbul; public space; informality - into the right category “Keywords” in the reference view of my EndNote Library.  Is there an automatic way to do it? Or just manually?

Kind regards
