Pull in existing summaries from various APIs

[jure]

PLOS, eLife, BMC all have versions of short summaries of their papers. We should try and pull those into ScienceGist.

Ben Miles https://twitter.com/bennmiles started with a version at the #hack4ac, which goes a little like this:

require 'json'
require 'nokogiri'
require 'open-uri'

# This is a short script to get demo content to populate an inial set of 'science gists'
# We started by trying to call the elife api directly, but it was bad
# then we tried to use content negotiation, but that is also flakey
# finally we searched the XML version of the paper with nokogiri
# then extract the xml node '<abstract abstract-type="executive-summary">'

  class Digest
    attr_accessor :gist, :doi  

    def initialize(doi, gist="no content")
      @doi = doi
      @gist  = doi2gist()
    end

    def doi2gist()
      strippeddoi = @doi.gsub(/dx.doi.org\//, '')
      uri = "http://elife.elifesciences.org/elife-source-xml/#{strippeddoi}"
      puts strippeddoi
      puts uri

      elife_raw_xml =  open(uri).read 
      digest_xml_path = 'abstract[abstract-type="executive-summary"]'

      xml = Nokogiri::XML(elife_raw_xml)
      digest = xml.css(digest_xml_path)
      digesttext = digest.text
      return digesttext.gsub(/abstract-2#{strippeddoi}.002eLife digest/, '')
    end
  end

#test doi1: 'dx.doi.org/10.7554/eLife.00782'
#test doi2: 'dx.doi.org/10.7554/eLife.00800'

digest = Digest.new('dx.doi.org/10.7554/eLife.00782')

puts digest.doi
puts digest.gist

A first attempt for this was made in https://github.com/ScienceGist/sciencegist/commit/7a043ab3d7b1c3525dde6e70ef524880e1925274. That uses the paper_summary gem, which for now only knows how to get summaries for eLife papers. It's a start, but I'll leave this open since we want to import or link to much more than just eLife.

I see that multiple summaries for a paper be submitted, but is there a way to tag them for the source's reputation? Maybe the upvote will be enough. This idea immediately reminded me of my MS/PhD classes in which we were assigned to read, summarize, and report on papers. +1 for such a great project!
