For a literature review I would like to apply the workflow ‘topic modeling on biomedical literature’, also explained in detail in a webinar.
However, I noticed the document grabber node did not allow search queries in a different search engine than PubMed. My current literature review focus is not in biomedical literature and thus I’d prefer to use an alternative search engine.
Is there a work around to use the same workflow in which loops are running to extract documents from, for instance, Google Scholar or Scopus?
I’d prefer to let KNIME run the search and pdf extraction. I would expect the alternative to be a pdf parser node after manually saving all pdf files.
Hope to hear your thoughts on the matter, thank you in advance.
