A great free Social Network Analysis Tool

I have been checking out social network analysis (SNA) tools which allow social network data (directly input or imported from external systems) to be displayed, manipulated and analysed graphically in a number of ways. I was also looking for SNA tools which are free or have a free version. Here's 4 tools which look very useful!

SNA tools typically allow a number of different types of social network analyses typically:

Centrality
Centrality as an actor-level coefficient reflects the degree of access to information (or resources) of an actor and hence the probability of that actor to acquire a leadership position in the group. As a network-level coefficient, centrality measures the distribution of information (or power) within the group.

Sociometric Coefficients
In a communication network, actor-level sociometric coefficients measure the level of communicational activity of a specific actor.

Distance-Related Coefficients
This category of measures is based on the concept of geodesic distance. Given two nodes of a network, say node A and node B, the geodesic distance from A to B is the length of the shortest possible path from A to B.

In terms of specific SNA tools here are 4 which have a free version:

Socilyzer - www.socilyzer.com. Socilyzer is built for managers and consultants to conduct their own basic analyses. The aim of the tool is to make it as easy as possible by integrating questionnaire design, data collection and data visualization. There are also good resources on the website explaining how to interpret the SNA diagrams. Well worth trying out.

SocNetV - "Social Networks Visualiser". It has a very nice gui, runs on Linux, Windows and Mac, supports GraphML and .net files, and is swift to compute centralities and distances. It does some network layout, as well. Check it out.

NodeXL. NodeXL is a free, open-source template for Microsoft® Excel® 2007 and 2010 that makes it easy to explore network graphs. With NodeXL, you can enter a network edge list in a worksheet, click a button and see your graph, all in the familiar environment Excel. NodeXL is an easy way into SNA for those who like spreadsheets.

Agna is a platform-independent application designed for social network analysis, sociometry and sequential analysis. Agna was the first good tool I found in this area when I wrote the original version of this article way back in 2008. Agna can still be downloaded but I don't believe there is any support or software updates. Agna still a neat tool and runs on both PC and Mac.

Wikipedia also now has a very useful page Social network analysis software which offers a comprehensive list of nearly 70 SNA tools and summarises them in a table covering Main Functionality, Input Formats, Output Formats, Platforms, Licensing and costs.

For a great introduction to social networks and social network analysis see these two articles by Richard Cross:

Another great (and free!) tool I recently discovered for analyzing social networks is "Social Networks Visualiser" or SocNetV. It has a very nice gui, runs on Linux, Windows and Mac, supports GraphML and .net files, and is swift to compute centralities and distances. It does some network layout, as well. Check it out:

Is Agna software still available? I get messages that the website is no more available?
I have published several presentations on SNA. The one that received the maximum interest is Social Network Analysis of Intangibles

Not sure if the company/website is still operational but I did a quick check and you can still download the Agna software from here:

Hi Anani

You have some excellent stuff on SNA - thanks for sharing.

Best Regards

KEN

It is also worth checking out Netdraw - another free SNA tool available from

https://sites.google.com/site/netdrawsoftware/download

Netdraw is the visualization component within the UCINET commercial SNA package

If you use the software, please cite it. Here is a sample citation:

Borgatti, S.P., Everett, M.G. and Freeman, L.C. 2002. Ucinet for Windows: Software for Social Network Analysis. Harvard, MA: Analytic Technologies.

Social networks are characterized by fast time dynamics. A nice software to display networks, Cytoscape 3.0, supports now layout of dynamical data. Check it out!

Thanks for sharing, I like great article at your site. Good luck!

 


Bioteams Books Reviews

Mobile business applications framework

Mobile business applications framework

In a just published book Work Goes Mobile by Michael Lattanzi, Antti Korhonen and Vishy Gopalakrishnan, authors of Nokia’s mobility master plan, propose a very useful application profiling scheme to establish the degree to which a business could exploit mobile technologies in their broadest sense. This approach would also be very useful for establishing the support requirements for virtually networked teams.
