7:00 – 5:30 ASRC

  • How Le Monde is taking on fake news
  • Thinking about Jonathan Albright‘s work. How is it crawled? Is it really just inbound links? Can I get the data? I need to ask.
  • Back to Sociophysics.
    • Clustering coefficient (video)
      CC = 0
      numNodes = 0
      for(i = 0 to max)
      	for(j = 0 to max)
      		n = node(i,j)
      		k = n.numNeighbors()
      		a = n.numLinksBetweenNeighbors()
      		n.setNodeCC((2*a)/(k*(k-1)))
      		CC += n.getNodeCC()
      		numNodes++
      CC = CC/numNodes
    • Clustering coefficient ordering: random -> small world -> regular
  • Got the NMF built into CorpusManager. Here’s the first four chapters of Moby Dick as:
    • BOW: there think harpooneer about little landlord sleep could would
    • TF-IDF: nantucket harpooneer queequeg landlord euroclydon bedford lazarus passenger circumstance
    • NMF: nantucket harpooneer queequeg landlord euroclydon bedford lazarus passenger circumstance
    • BOW/centrality: there think would queequeg could about whale little first
    • TF-IDF/centrality : about harpooneer night landlord stand light nantucket where other
    • NMF/centrality : harpooneer queequeg landlord water nantucket circumstance sailor passenger about
    • (centrality with equalized docs)
  • Meeting with Shimei
