Social Network Analysis


A star Red Star indicates tools that combine power (advanced, multiple, or flexible features) with ease of use. The star tends to be reserved for tools capacious enough for multiple uses or add-on uses that they might also be called "platforms" (e.g., TAPoR, Many Eyes, or Google Earth).  (Other tools may be more powerful, or more easy to use, but not in combined balance.)

Circos visualizations

"Circos is a software package for visualizing data and information. It visualizes data in a circular layout — this makes Circos ideal for exploring relationships between objects or positions. . . . Circos is ideal for creating publication-quality infographics and illustrations with a high data-to-ink ratio, richly layered data and pleasant symmetries. You have fine control each element in the figure to tailor its focus points and detail to your audience."

Netlytic social network discovery and visualization

Netlytic social network discovery and visualization

"Netlytic is a free web-based system for content and social network analysis. The main goal is to provide researchers and other interested parties with an automated system for analyzing text-based communal interactions. Netlytic uses a web-based platform that incorporates various text mining techniques and interactive visualizations to allow researchers to access and analyze text-based datasets remotely and share their preliminary results with their collaborators....  What can the current version of Netlytic do?  Import and clean your data set from an RSS feed, an external database or a text file.  Find and explore emerging themes of discussions.  Build and visualize Chain Networks (social networks based on the number of messages exchanged between individuals) and Name Networks (social networks built from mining personal names)."
