The Manchester social networks group (MSNG) is a cross-disciplinary research group located in the School of Social Sciences. MSNG aims to discuss and to promote the application and development of Social Network Analysis methodology to answer important research questions in social science. The following SNA topics are of interest to the group: Data collection for social network analysis Longitudinal networks and network formation Neighbourhood and network variations in social and health outcomes Qualitative network analysis Social Networks and Social Movements Statistical modelling of social networks Visualising and describing social networks

SNA package used for "ordinary" data (one line of data for each case) and for network data (two files - "nodes" and "links" )

NodeXL is an open-source template for Excel 2007 and 2010 which provides the utility to create a hierarchical network edge list. With NodeXL, you can create a customizable hierarchical network graph and zoom, scale, or pan it for a more refined look of added data. Networks can also be imported or exported to a variety of file formats. For example, you can create a graph displaying a company's chain of command and structure of subordinate employees. NodeXL provides the convenience of eluding difficult applications, arcane file formats and programming language for creating such graphs. You can even import a list of your Twitter followers or YouTube and Flickr connections, to create graphs representing your social network.

Cogito semantic technology The material analyzed through the intelligence process is mostly unstructured: communications, conversations, data, news, etc., and rarely has an organized form, such as a database structure. As a consequence, the activities of analysis and processing can be highly resource consuming, and prone to error. The work of analysts and knowledge workers remains essential, and technology cannot fully replace it (and never will). Nevertheless, with new generation software based on semantic analysis, it is now possible to understand data automatically as well as to support reasoning and stimulate intuition.

The advantage of NodeXL, particularly for graphing Twitter communities, is it has built-in features for grabbing the data for you. Not only that the coding is clever enough to handle the data collection for mere mortals, so when you hit your rate limit NodeXL waits until it should be able to get more data. NodeXL also has "built-in connections for getting networks from Flickr, YouTube, and your local email. Additional importers for Exchange Email, Facebook, and Hyperlink networks are available".

Luka Potkonjak has contributed a new feature to NodeXL: edge bundling.  Following on the heels of the release of curved edges in version. 175, we now provide a way to gather parallel edges together into "bundles" that travel together until they diverge close to their destinations.

A number of instructors have been using NodeXL to help teaching social network analysis. It is relatively easy to use compared to many other network analysis and visualization tools, while still providing a rich set of metrics and visualization features. It is also free and integrates with Excel 2007, which many users are familiar with. This page is meant to collect information that can be useful in teaching with NodeXL.

KeyLines is a JavaScript toolkit for visualising networks. It works in all major browsers, and on all platforms, including the iPad. It uses HTML5 but also works on old versions of Internet Explorer. KeyLines is ideal for organisations who want to migrate from legacy Java, Flex or Silverlight apps to the new world of HTML5.
