SocNetV v2.1 “fixer” released

Your favorite social network analysis & visualization free software project, Social Network Visualizer, has released a new version. SocNetV v2.1 has the quite eloquent codename “fixer” and it is available for Windows, Mac OS X and Linux from the project’s Downloads page. See some nice screenshots of SocNetV in action.

SocNetV 2.0 released, built for stability & speed! – New features galore

I am happy to announce a new major release of Social Network Visualizer (SocNetV), the Social Network Analysis software. SocNetV v2.0 comes with a major code overhaul for stability and performance boost, improved GUI with a new panels layout, and nice new features for easier social network analysis, such as separate modes for graphs and digraphs, permanent settings/preferences functionality, edge labeling, recent files, keyboard shortcuts, etc. Also there are improvements in Force-Directed layouts, i.e. Fructherman-Reingold. The new version supports Windows, Linux and Mac OS X. Binary installers and source code packages are available from the project’s Download page. See below a walk-through of the new features.

SocNetV version 1.9 is here, with LU decomposition and a Qt showcase!

Another release has just emerged from the depths of the Social Network Visualizer project! The new version 1.9 fixes important bugs and brings a vastly improved matrix inverse algorithm, thanks to the newly implemented LU decomposition. Of course, the new algorithm speeds up all other routines which depend on the inverse of a matrix, such as the Information Centrality algorithm.

Also, SocNetV v1.9 brings a revamped -and corrected- PageRank Prestige routine. Up to v1.8, the PageRank algorithm was using the original Page&Brin formula which lead to somewhat different results compared to other SNA applications. From this version, SocNetV uses the correct formula and computes comparable results (yes, we tested :)).

Source code, Windows zipped executables, Mac OS image and binary packages for major Linux distributions are as always available from the project’s Downloads page. Have fun with the new release!

Also, I am happy to report that the Qt project has added SocNetV to its ‘showroom’ page, along with many other nice Qt applications. There is also a showroom page dedicated to SocNetV with nice screenshots and a brief description of the application. Kudos to Kojo Tero, of Qt Company, for this!

The new features in versions 1.3 and 1.4 of SocNetV

Over the last weeks, the Social Networks Visualizer (SocNetV) project has released two new versions which brought useful new features and of course a lot of bugfixes. The latest v1.4 closed even 4 years old bugs!

socnetv-v1.4-erdos-random-social-network

socnetv-v1.4-erdos-random-social-network

The strongest new feature of SocNetV is multirelational editing. You can now load or create a social network on the canvas, for instance depicting the friendship ties between kids in a classroom, and then add a new relation (Cltr+Shift+N) which it might depict i.e. “likes” between pairs of the same clasroom kids. And you can be do this very easily as we will demonstrate in this article.

SocNetV version 1.2 released with lots of goodies!

A new version of SocNetV, the cross-platform tool for social network analysis and visualization, has been released. Version 1.2 brings a major GUI overhaul, a new conceptualization of “prominence” measures, new importance and reachability measures, many new visualization layouts based on the new indices, and fixes a slew of bugs (see below).

SocNetV 1.0 Qt5 is out! RPMs included :)

If you’re interested in Social Networks Analysis and Visualization (I’m not talking about FB/Twitter here!), check out our latest and greatest release of SocNetV, version 1.0.

SocNetV (Social Networks Visualizer) is now based on Qt5/C++ framework and has new great features, such as PageRank network analysis and, of course, layouts. At the moment, there is only source code and Fedora/openSUSE packages available from our project page in SourceForge. Soon, Debian/Ubuntu packages will be released as well. Warning: There are SocNetV packages in the official Debian/Ubuntu repositories, but it’s a very old version. Maybe a brave debian developer (serzan?) could fix this soon 🙂

Needless to say: SocNetV is a GPL3 application. It is free software (free as in freedom). You can copy it, modify it and redistribute it as long as any derivative work remains free software. Enjoy.

SocNetV on Maemo-N900?

Easy. Short of.

I did this ‘experiment’ to test how much cross-platform Qt really is. I wanted to see if SocNetV can run on Maemo with no modifications whatsoever. These are the steps I followed:

1. Downloaded and installed the Xephyr X11 server (this is a small X11 server that runs inside ‘normal’ X and provides a virtual device screen where you see all the Maemo applications running):

sudo apt-get install xserver-xephyr

2. Downloaded and installed  Scratchbox and  Maemo SDK  in my laptop (Kubuntu x86/lucid).  I followed the straightforward instructions from the Maemo wiki and especially “Installing Maemo 5 SDK on x86-32 Debian based distribution“. It’s only seven steps and circa 100MBs of total downloads…
