October 2-3, 2014: Digital Strategies for Development Summit, Asian Institute of Management, Makati City, Philippines – Mapping social media networks

22SepMay 7, 2015 By Marc Smith

20141002-AIM-DSDS-Banner

 

I attended and participated in the October 2-3, 2014 Digital Strategies for Development Summit hosted by the Asian Institute of Management and held in Makati City, Philippines.

The event gathered 50 speakers from around the world and more than 300 participants to focus on the role of digital and social technologies for civic needs.  The summit focused on bringing people from many communities into a discussion of how technology can be used for:

“…enabling a better society and an empowered community? How can various stakeholders, including Government, Private Sector and Civil Society gain more momentum for their core mandates by leveraging the use of digital technology enabled solutions? Can Digital Technology create a platform for better collaboration and cooperation amongst various stakeholders?”

I spoke about the role social network analysis can play in understanding the emerging world of social media and computer mediated collective action.

On September 20, 2013 I will participate in a workshop on social media network analysis at the Community, Journalism & Communication Research Center at the School of Journalism in the College of Communication at the University of Texas – Austin

The event will start Friday at 11:00AM at the BELO CENTER FOR NEW MEDIA.  Bring data, questions and a copy of NodeXL for hands-on assistance.

The workshop will focus on the application of social network analysis to social media and the content exchanged through it.

The graph represents a network of 780 Twitter users whose recent tweets contained “@utaustin”, taken from a data set limited to a maximum of 10,000 tweets. The network was obtained from Twitter on Friday, 30 August 2013 at 18:22 UTC. The tweets in the network were tweeted over the 2-day, 3-hour, 55-minute period from Wednesday, 28 August 2013 at 14:25 UTC to Friday, 30 August 2013 at 18:20 UTC.

Dr. Cody Dunne speaks about Network Motif Simplification at the recent CHI 2013 conference in Paris, France

06MayMay 7, 2015 By Marc Smith

Here is Dr. Cody Dunne speaking about a new information visualization technique called “Network Motif Simplification” at the recent CHI 2013 conference in Paris, France.

Networks, no matter how complex, are composed of simpler, smaller structures, called motifs.  Some of these structures are easy to identify, like the pattern of a “star” where a single node acts as the sole connection to a connected component for one or more “pendant” nodes with a single tie.  Another common pattern are nodes that are “parallel bridges” which share the only two connections they have with two or more other nodes.  These common structures  can be identified and removed and replaced with more efficient and comprehensible representations.

His paper with Prof. Ben Shneiderman at CHI 2013, “Motif simplification: improving network visualization readability with fan, connector, and clique glyphs“, demonstrates a novel method for improving the quality of network visualizations.  Common network motifs appear frequently in networks.  In network motif simplification these patterns are removed and replaced with simpler composite images:


Motifs collapse into simple glyphs

The result is a simplification of the network visualization, removing clutter to reveal the core structural properties of interest.

2007 United State Senate is reduced to a simplified form

This method for collapsing complex network graphs into simpler forms has been implemented in NodeXL.  Look for the feature in the NodeXL Ribbon menu, in the NodeXL > Analysis > Groups > Group by Motif… option.

The feature allows users to select the types of motifs that should be recognized and collapsed:

The paper has been reviewed by Stephen Few on the Perceptual Edge Visual Business Intelligence blog.

This is a sample NodeXL graph that represents a network of 106 Twitter users whose recent tweets contained “passbac”. The network was obtained on Wednesday, 30 January 2013 at 01:09 UTC. There is an edge for each follows relationship. There is an edge for each “replies-to” relationship in a tweet. There is an edge for each “mentions” relationship in a tweet. There is a self-loop edge for each tweet that is not a “replies-to” or “mentions”. The tweets were made over the 7-day, 5-hour, 32-minute period from Tuesday, 22 January 2013 at 17:40 UTC to Tuesday, 29 January 2013 at 23:12 UTC.

How to plot a network in a “polar” layout using NodeXL

03MarMay 7, 2015 By Marc Smith

When a particular node in a network is of special interest it can be useful to create a network visualization in which it is located at the center of concentric rings of vertices.

NodeXL supports a “Polar” layout in which each vertex has two values that govern its location: distance from center (“Vertex Polar R”) and the angle around the clock (“Vertex Polar Angle”).

Using a random network, we added two columns to the Vertices worksheet that we called: Ring (or “Vertex Polar R”) and Rotation (or “Vertex Polar Angle”).  We then assigned values for the “Ring” and the “Rotation” for each Vertex:

2013-03-03-NodeXL-Vertex Polar Data - Ring and Rotation

These values can then be mapped to the location for each Vertex using the NodeXL Autofill columns feature:

2013-03-03-NodeXL-Autofill Vertex Polar Data

When these values are applied to the network visualization and the layout is set to “Polar” the visualization repositions each vertex into a position around a ring.  The values are set by mapping Vertex Polar R to “Ring” and Vertex Polar Angle to “Rotation” and then selecting “Autofill”.  The result is a single ring plotted around a core:

2013-03-03-NodeXL-Visualization of Vertex Polar Data

To see this more clearly, I built a larger random network with 100 vertices and added two more “rings”.  The resulting image looks like this:

2012 – August 9 – AEJMC – Chicago – NodeXL Workshop

09AugMay 7, 2015 By Marc Smith

I presented a Workshop on Social Media Network Analysis and NodeXL at the 9 August 2011 – Association for Education in Journalism and Mass Communication (http://www.aejmc.com) in Chicago.

See: http://www.aejmcchicago.org/

The Association for Education in Journalism and Mass Communication(AEJMC) is a nonprofit, educational association of journalism and mass communication educators, students and media professionals. The Association’s mission is to promote the highest possible standards for journalism and mass communication education, to cultivate the widest possible range of communication research, to encourage the implementation of a multi-cultural society in the classroom and curriculum, and to defend and maintain freedom of communication in an effort to achieve better professional practice and a better informed public.

Our session was:

Using NodeXL for Social Network Analysis
— 
2 pm to 5 pm
Presented by Communication Theory and Methodology Division
This pre-conference workshop examines social network analysis. Social network analysis can be used to examine message boards, blogs, and friend networks (amongmany other phenomena). Participants will learn to use the NodeXL program to conduct a network analysis.
