Attended by Bonnie, Tim, Russell, Micah, Bryan, and Bruce

Agenda

  • Hear Tim's accomplishments on SNA stuff
  • Hear Russell's plans on SNA stuff
  • mention usefulness of postscript/image viewer, people should keep their eyes out
  • Update NWB website
    Postpone the rest topics
  • What we need to do soon-ish to advance the scientometrics filling
  • Plan of deliverables from now till the end of the project (details on Jan and Feb)
  • more on process model?
  • more on svn rearrangement?

Meeting Notes

  1. Hear Tim's accomplishments on SNA stuff
    See Ticket 173
  • Detect multiple/multiplex relationships (edge attributes)
    Implementation: If the edge list in the network have additional edge attibute column(s) beyond source and target, NAT count it as multiple/multiplex relationships. The NAT bookkeeps a list of edge attributes with numerical values and list of edge attribute with non-numerical values.
  • Detect whether the network is weighted or not -- should be rephrase it as valued or not Principle: detect edge attributes,
    • If has more than one numerical edge attribute --> valued network.
    • If only has one numerical edge attribute and only has one value --> unvalued.
    • If only has one numerical edge attribute and more than one value --> valued.
  • Detect isolated nodes
  • Calculate Mean value of edges/arcs
    For each edge attribute with numerical value, calculate the mean
  • Calculate Maximum value of edges/arcs
    For each edge attribute with numerical value, get the maximum value for that edge attribute and report it.
  • Calculate Minimum value of edges/arcs
    For each edge attribute with numerical value, get the minimum value for that edge attribute and report it.
  • Number of observations (postpone)
  • Calculate density for weighted network -- calculate the density based on each edge attribute with numerical values
  1. Hear Russell's plans on SNA stuff -- works required for Sunbelt
  • Russell will work on 5-6 algorithms as follows
    • Symmetrizing (Turning directed/asymmetrical into undirected/symmetrical) -- must done (1)
    • Dealing with Diagonal (self-loops) -- must done (2)
    • Dichotomizing (Turning weighted/valued into unweighted/unvalued) -- must done (3)
    • Transposing -- must done (4) Russell
    • Deleting isolates -- Use K-Core extraction (Russell recommend as must have)
    • Unpack multiple relationships (either through clearly separate relationships or via edge attributes.)
  • Duygu's 2-4 algorithms: edge betweenness and freeman's closeness centrality, reciprocity and transitivity. Bonnie will work with Duygu for the algorithm integration
  • Tutorials (Russell+Ann+Bryan+Bonnie)
  • viszards (Russell, Elisha, Katy)
  • NWB flyers & CDs
  • Two posters (one nwb and one viszards)
  • Business cards
  • Demo preparation
  1. mention usefulness of postscript/image viewer, people should keep their eyes out.
    We need to find a good postscript/image viewer and integrate it to the NWB tool in the near future.
  1. Update NWB website
    Bruce propose to use wiki. However the css in wiki seems not that flexible. We want to have some quick fix/upate for sunbelt. Need Katy's input on Monday.
