This is a good demonstration of several features in NodeXL: social media network importers (in this case from Twitter), the use of a variety of layouts, auto-fill column mappings, and dynamic filters to reveal some important structures, groups and people in the graph.
Note! Excel has issues with security and workbooks. The easiest way to use that file is to open a blank NodeXL template and use the “Import from older workbook ” feature to pull the data into a workbook that your copy of Excel *can* trust.
Earlier in the year, in March 2009, many people gathered at De Neve Plaza at UCLA to remember Peter Kollock.
On Monday, September 14th, at 10:30 PST, I met on the phone with Jerry Michalski and other participants for one of his regular weekly Yi-tan conference calls to discuss the scholarship and personal legacy of Peter Kollock. In this podcast, I spoke about my years of working with Peter to apply the models of collective action dilemmas, common pool resources, cooperation, and conflict to the creation of Internet social institutions and resources. I discussed Peter’s work with his colleague Jodi O’Brien, and the lasting impact of his research into studies of cooperation, collective action, and common goods as well as his impact on students, business, and the field of social science. Jodi and Peter were colleagues and co-authors for many years, creating a widely used text The Production of Reality: Essays and Readings in Social Psychology as well as several other publications. I worked with Peter while studying for my Ph.D. at UCLA in Sociology. Peter and I wrote about the sociology of the Internet together and co-edited a book Communities in Cyberspace.
I will post a few links to some of Peter’s work that has had the most impact on me in upcoming posts.
My colleague, Eduarda Mendes-Rodriguez, recently demoed NodeXL at the Microsoft EU Innovation Day event in Brussels, Belgium. She illustrates the value of network analysis in general with a social network diagram representing the voting patterns of United States Senators in 2007. The results show the clear party-line clustering and the presence of a few fence sitters, one of whomn just recently changed party. I think the difference between the two party’s internal cohesion is an interesting observation as well.
Eduarda does a great job demonstrating the ease with which a sophisticated analysis can be implemented via the NodeXL interface.
NodeXL is about to cross 8,000 downloads and has several releases in the works to add better tools for laying out a social network diagram.
