keywords for papers RRS feed

  • Question

  • Hello,

    For those of us who want to use the keywords associated to each paper, could you explain how these keywords are generated? They seem to be some noun phrases extracted from the papers' title/abstract, but some times these keywords don't exist in either of them. Do you consider full text to extract them? are you using the paper's metadata keywords (usually given by the authors themselves) ?

    Could you provide a short explanation? You extract the top noun phrases from the whole field and then each paper is associated with some of them? or something much more complicated?

    Thank you
