| 0 Comments | 0 TrackBacks

This week, there are 2 papers to read and prepare to discuss + 3 videos, all presented at IEEE VisWeek (2 in VAST sessions and 1 in an InfoVis session).  The focus is on different aspects of analyzing and using microblog data.  As noted above, the 3rd citation is just for reference for anyone who wants to follow up and actually read the paper out of interest or for design ideas.
