Free and Open-Source Tool for
Social Network Analysis

Social Network Visualizer (SocNetV) is a cross-platform, user-friendly free software application for social network analysis and visualization. Social Networks are displayed and analyzed as mathematical graphs, where vertices depict actors/agents and edges represent their relations.

The application enables you to import social network field data, edit actors and links through point-and-click, analyse their social and graph properties, produce reports for these properties and embed visualization layouts to the network.

SocNetV computes standard graph-theoretic properties, such as density, diameter, geodesics and distances (geodesic lengths), connectedness, eccentricity, etc. It also computes advanced structural measures for social network analysis such as centrality and prestige indices (i.e. closeness centrality, betweeness centrality, information centrality, power centrality, proximity and pagerank prestige), triad census, clique census, clustering coefficient, etc.

The application supports various layout models based either on prominence indices (i.e. circular, level and nodal sizes by centrality score) or on force-directed placement (i.e. Eades Spring Embedder, Fruchterman-Reingold, etc) for meaningful visualizations of the social networks.

With SocNetV you can draw social networks with a few clicks on a virtual canvas or load field data from various social network formats supported such as GraphML, GraphViz, Adjacency, Pajek, UCINET, etc.

It also supports multirelational loading and editing. You can load a social network consisting of multiple relations or create a social network on your own and add multiple relations to it.

Furthermore, you can create random networks using various random network generation models (Barabási–Albert Scale-Free, Erdős–Rényi, Watts-Strogatz Small-World, d-regular, ring lattice, etc) or recreate famous social network analysis datasets, i.e. Padgett's Florentine families.

A simple web crawler is also included to automatically create "social networks" from links found in a given initial URL. The crawler scans the given web page for links and visualizes the network of all webpages/sites linked from it.

There is also comprehensive documentation, both online and inside the application, which explains each feature and algorithm of SocNetV in detail.

Source code, packages and executables for Windows, Linux and Mac OS X are available in the "Downloads" menu.

The program is Free Software, licensed under the GNU General Public License 3 (GPL3).
You can copy it as many times as you wish, or modify it, provided you keep the same license. The documentation is also Free, licensed under the Free Documentation License (FDL).
