Hello all, I’m Castle Sinicrope, Webmaster for the Social Network Analysis TIG since 2011 and Policy Analyst at Social Policy Research Associates, a research, evaluation, and technical assistance firm in Oakland, CA. For newcomers to social network analysis, picking the right software package can be a daunting task. Here’s an overview of four commonly used tools for visualizing and analyzing networks:
NodeXL: A free, open-source spreadsheet add-in for Microsoft® Excel 2007 and 2010, NodeXL integrates with social media tools like Twitter and Facebook, allows users to generate maps, and calculates common network statistics.
Strengths: Beginner friendly, active on-line support community
Rad Resources: Marc Smith’s previous AEA365 post, co-authored how-to guide, Analyzing Social Media Networks with NodeXL: Insights from a Connected World, and YouTube introduction to NodeXL.
Gephi: Hailed as the “Photoshop for graphs,” Gephi is a free, open-source standalone program for interactively exploring and visualizing networks and complex systems. Gephi includes common statistics for social network analysis and supports main file formats from other software programs.
Strengths: Powerful and flexible visualization tool
UCINET/NetDraw: Comprehensive and well-established, UCINET is an all-in-one program that supports advanced social network analyses and network visualization through an accessible user interface.
Strengths: Calculates sophisticated network statistics
Cost: $40 (students), $150 (faculty), $250 (corporate). Faculty and corporations can purchase site licenses at a discount. NetDraw, UCINET’s program for visualizing network data, can be downloaded for free here.
Rad Resource: Hanneman and Riddle’s Introduction to Social Network Methods, a comprehensive on-line textbook that introduces basics of social network analysis through UCINET.
R: Not for the faint of heart, R does not have a typical user interface. To succeed with R, you need to be comfortable with programming and writing your own code. The reward? Flexibility and ability to clean your data, visualize your networks, and generate network statistics, all in the same program.
Strengths: Very customizable and powerful
Rad Resource: Stanford University’s R for Social Network Analysis website includes step-by-step instructions for getting started with SNA in R.
Stay tuned for demo posts for NodeXL, Gephi, and UCINET later this week!
