Some network data sets are created or received in the form of a matrix.
A matrix can be directed or undirected. In this example, we will import a directed network.
First open a blank NodeXL template.
Next open the matrix workbook in the same instance of Excel (just drag it into the title bar of the current NodeXL Excel instance).
Here is a simple asymmetric matrix with weights for tie strengths.
To import this matrix, switch back to NodeXL
and select the Data>Import>From Open Matrix Workbook:
A matrix may or may not have labels (row and column headers) and the user should define what their data set looks like.
The matrix may represent a directed or undirected network (if it is undirected the matrix must be symmetrical!).
This results in data appearing in the Edges worksheet of NodeXL:
This can then be visualized as a network where the edge weights are used to set the thickness of the lines connecting two nodes:

THIRD BIENNIAL MEETING OF THE WORLD BANK GROUP’S
INTERNATIONAL CORRUPTION HUNTERS ALLIANCE (ICHA)
ENDING IMPUNITY FOR CORRUPTION
December 8 – 10, 2014, World Bank, Washington DC
I will speak about the value of a network perspective for the discovery of fraud and corruption in financial data at the December 9th session of the World Bank’s upcoming meeting of the Stolen Asset Recovery Initiative.
“The World Bank Group’s International Corruption Hunters Alliance (ICHA) brings together heads and senior officials of corruption investigating bodies and prosecuting authorities, anti-corruption experts, academics, and representatives of international organizations from over 130 countries. The 2014 meeting of the Alliance will focus on fighting corruption – and the vast illicit outflows generated by corruption – by sharing know-how and experiences in the use of both traditional and alternative corruption fighting approaches.”
All financial transactions create a network as one person transfers money from one account to another. A list of transactions creates a web of connections with an emergent shape or pattern. Within these patterns are key positions occupied by people with special power in the network. Mapping these transaction networks can reveal the hidden traces of financial crime.

The 2014 Restaurant Executive Summit will be held on November 3 – 5, 2014 at the Ritz-Carlton in Ft. Lauderdale, Florida.
The theme of the event is “How to Feed Consumers with a #Digital @ppetite”
I will speak about the ways that restaurants and dining experiences are discussed in social media. I will show network maps that visualize the relationships among people who talk about restaurants created with the free and open NodeXL social media network analysis and visualization application.
Here are some recent NodeXL social media network maps for mentions of major chain restaurants featured in the NodeXL Graph Gallery:
These maps illustrate the shape of the crowd that gathers around the names of major chain restaurants. A few Twitter user accounts occupy key positions in these network crowds, these are the influential voices that are repeated widely by others.
Closer inspection (click through for details) reveals smaller groups or clusters which form as a smaller set of people interact with one another more than with the larger population. These groups have distinct topics of interest which are summarized in the content report associated with each visualization.
The network and content report can reveal the topics of interest to various groups in the discussion as well as the key people within each group.

The social media landscape is complex. Social media network analysis makes it easier to understand and navigate social media.
Using the NodeXL social media network analysis add-in for Excel from the Social Media Research Foundation, I have made a large collection of network visualizations and reports, many of which can be seen in the NodeXL Graph Gallery.
Now that I have seen many social media network maps I observe that marketers are often interested in building “broadcast” network patterns. This is one of the six basic social media network patterns documented in the recent Pew Research Internet Project report about Mapping Twitter Topic Networks.
There are at least three phases of possible success for a social media marketing effort: phase 1, you get an audience of people who will retweet what you post. Phase 2, some of your audience gets its own audience for the content they repost from you. Phase 3, a dense web of relationships emerges, a community of relationships. This is a desirable phase because it sustains the conversation event when new messages from the brand account are not created.

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.

RIS News, the leading media organization for retail executives, and Consumer Goods Technology, the leading source for the consumer goods sector, have partnered to launch the 2014 Retail and Consumer Goods Analytics Summit. The conference hashtag is #RCAS2014.
I will speak on September 12th at the event. I present the Closing Keynote from 2:30 – 3:10pm on Friday. My talk is titled:
The Impact of Social Media on Data & Analytics
Speaker: Marc Smith, Director, Social Media Research Foundation
People talk about the products and services the use, love or hate all the time in social media. These conversations can be better understood through perspective of social network analysis. Network theory views the world as a web of connected people. Network analysis builds measures and visualizations of collections of connections to reveal the key people, groups and issues in these conversations. Using social media network maps and reports the confusing landscape of tweets and posts comes into focus. Information visualizations of the virtual crowds of people gathered around every brand, product, event, or service highlights the range of variation in the shape of these crowds. Six different patterns have been identified so far, allowing social media managers to recognize the nature of the brand network they have and the nature of the network they want to have. Network measures are useful as KPIs for tracking not just the size and volume of a social media stream, but also the shape and structure of the pattern of connections. The six patterns: divided, unified, fragmented, clustered, and in and out hub and spoke, are a useful guide to strategic engagement in social media.
