Literature text exploration to display statistics in Pubmed

Question

[lessismore]

Dear all,

im searching for an automated method to display number articles showing a certain word in their abstract, or a combination of words, in order to display the relevance of a specific topic per year. Is there any automated tool in R to do this?

Thanks in advance

Eventually i've also found a very useful resource called bibliometrix:

website: https://www.bibliometrix.org/
R-package: https://cran.r-project.org/web/packages/bibliometrix/index.html
