I would like to obtain mainly two things. Suppose that the
tag (or topic) I'd like to mine is
1) I'd like to find out all
keywords (where ever possible.. I guess relatively recent papers alone have keywords?) ( or any other equivalent
main words) that are associated with this topic. I am interested in creating a
tag cloud or
word cloud. I think its a cool opening slide in a presentation. What do you guys think?
2) I'd like to mine for
pioneer (major findings / breakthroughs) papers in this field (probably more restriction criterions should apply here, such as, humans or plants etc..), if not,
most cited papers, from all available papers. This is basically for
literature reading. Basically, how does one get across in finding papers that one should definitely have read??
I know how to generate a word cloud in R. I'd like to know if its possible to extract these information somehow from pubmed (using the
tm R-package possibly?).
Thank you in advance for your suggestions, Best, Arun.
