Once you start creating and collecting network graphs you may find you can build a significant collection: hundreds, thousands or tens of thousands of graphs may result from a study or on-going monitoring project. In a series of features in the NodeXL project we have enabled a workflow for constructing many social media network graphs [...]
As mobile devices become a major method for authoring and consuming social media, location data is increasingly a part of many posts, tweets, check-ins, and messages. Many Twitter clients, for example, can add the user’s current latitude and longitude to the metadata associated with a tweet. Other systems like Facebook Places, Google Latitude and Foursquare [...]
Eduarda Mendes Rodrigues, (University of Porto) from the NodeXL team has created a sample network file that attempts to highlight the functions and applications of the social media network analysis toolkit. The latest release of NodeXL now contains this sample file: In this map nodes represent the major feature groups and functions in the NodeXL application. [...]
Here is a recent collection of NodeXL related activity and commentary: Here is a great review of Analyzing social media networks with NodeXL: Insights from a connected world by Gerd Waloszek, SAP User Experience book reviewer: http://www.sapdesignguild.org/community/ book_people/review_ana_sm_nw.asp Several reviews of the book Analyzing Social Media Networks with NodeXL: Insights from a connected world have [...]

Analyzing Social Media Networks with NodeXL
NodeXL is the free and open add-in for Excel 2007/2010 that supports network
overview, discovery and exploration. Supported by Microsoft External Research
for 3+ years, this effort has produced a game-changing software tool that enables
students, researchers, and professional community managers to extract and
download networks from email, Twitter, YouTube, Flickr, WWW, etc. Then they
can compute network analytic metrics, filter out less relevant features, apply
multiple layout algorithms, and produce compelling yet comprehensible displays
that reveal actionable insights about complex social processes.
I am coming to understand what is interesting in any particular network visualization by looking at many network visualizations. Using NodeXL, I have made several maps of social media networks of people talking about several topics of interest from current events to conferences I attend. You can find a collection of them on flickr. I [...]
