Dear All,

I am looking for a recommendation on a:

* user friendly
* easy to learn for novices
* strong visualisation possibilities
* open software

packedge for SNA.

We are especially interested in track-changes / time series visualisation.
Firts entry point for us is ToughGraph.....
Please shoot.

Thank you, Jaap. What is SNA? I googled it and got:
John Wayne Airport (SNA), Orange County, 
California School Nutrition Association 
The Southern Nursery Association
IBM Systems Network Architecture
SNA - Suburban Newspapers of America
Singapore Nurses Association

I am pretty sure it woudl be one of the above and it has nothing to do with nurses or nutrition:)

Social Network Analysis?

== Boris Jaeger, 2008/11/12 ==

atanu,

try this search SNA in combination with an other key word provides (e.g.visualization) and you'll find out that SNA means

Social Network Analysis

I hate abbreviations others ay not know, too!

== Jaap Pels, 2008/11/12 ==

Sorry All.
SNA = Social Network Analysis

== Rachel Cardone , 2008/11/12 ==

Hi Jaap,

I have a dumb question - what's sna?

== James J. Tarrant, 2008/11/12 ==

I think it might be social networking analysis.

[http://www.analytictech.com/ucinet/ucinet.htm UCI net] is not open source but is free for 30 days, and "For longer use, individual students pay $40, schools & government pay $150, and corporations pay $250."

This is widely used by the people that do SNA at my university and it seems to be easy to use.

Hi Jaap,

UCNET is good. My pick would be [http://vlado.fmf.uni-lj.si/pub/networks/pajek/ Networks / Pajek]

It has the capability to work with files created with other SNA software as well. It is free.

Jaap,

I don't think you will find one single tool which will do this. I do Social Network Analysis for a living and I think this is one of the challenges in
the field. There is a good listing of tools in Wikipedia (just search for Social Network Analysis), but none of them would be both user-friendly AND
free AND easy to learn etc.

We developed a survey tool called ONA Surveys (www.onasurveys.com) for collecting relationship data (like "who knows who"), and whilst I of course think it is terrific, it isn't free. Netdraw from Analytictech is a fantastic visualization tool, but I wouldn't call it 'user-friendly'...you
need to know what you are doing in the first place. Inflow is also great for visualization, but not free. Pajek also does visualization and is free (for
non-commercial purposes from memory), but not exactly easy to use. UCINET is certainly hard to use the first time you try it out, but popular with
researchers. It is cheap, but not free. Netminer is a little more sleek, but also much more expensive...

Keyhubs is a new'ish tool which combines surveying with visualization, but is very 'thin' and isn't free either.

To me is it obvious that the field undergoing a great deal of change (in terms of tools) and there is a great divide between the tools researchers
would be using and what practitioners doing it over and over again want.

There is a Yahoo group called ona-prac where you might want to post the question (ONA stands for Organizational Network Analysis....it is really the
same as Social Network Analysis, but people call SNA for ONA when it is used in a business context).

== Johannes Schunter, 2008/11/12 ==

Hi all,

we had a similar thread on this a few months ago, which's results were capt=red in the [http://www.km4dev.org KM4Dev] wiki/wiki/index.php/Social_Networ=_Analysis. There are a range of tools as well as trainings on SNA which ha=e been recommended.
