I am currently gathering info about the state of the art of some topic. What I want to do is to get statistics about how often the topic was mentioned in papers in combination with other keywords in the last couple of years.
Something like this:
Year "topic keyword1" "topic keyword2" "topic keyword3" 2017 81 420 121 2016 76 391 101 2015 64 358 92 ... ... ... ...
Is there a place where i can get this kind of information in an "easy to process" format? (I used ScienceDirect and other databases and copied the information by hand so far but that is not a good solution imho.)
Thanks in advance!
