Where to get statistics about papers mentioning specific keywords? 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!
What about google scholar? You won't get such a nice formated output, but you will get number of hits for each keyword or combination of keywords
