Enterprise Software Doesn't Have to Suck: Social Network Analysis using R and Gephis
After learning the basics of R, I decided to learn something harder last week. I picked Social Network Analysis (SNA) to learn the concepts of SNA and R. My primary interest in SNA is visual exploration of networks, so I needed to find a tool first. Which tool to use for visual SNA? Features needed: 1) graphical representation of network 2) visually navigate the graph (zoom in/out, drag) to explore large graphs 3) manipulate the graph (filter nodes, edit/delete/group nodes and same for edges) 4) free, preferably open source. I found out that R has good libraries like SNA (checkout Drew Conway's tutorial) and iGraph (see this tutorial) for social network analysis. So I continued my hunt for a good tool for visual SNA and discovered Gephis, an open source app for visual exploration. WARNING: SNA with Gephis is addictive. After you download Gephi, checkout Gephi quick start guide to get your bearings. Gephi Features Tour from gephi on Vimeo. Web rendition of these graphs is also possible.
