RRSI2014: Gephi (and a little bit of Palladio)
David Wrisley, American University of Beirut, @DJWrisley, firstname.lastname@example.org
During this session, I will be introducing briefly some concepts of networks for a variety of subjects and at multiple scales. A variety of readings have been placed in the Networks folder of Zotero as background reading.
The required readings for the morning include Weignart's article "Demystifying Networks," Latour's "On actor-network theory" and Barabasi/Bonabeau's "Scale-Free Networks." There are three useful recommended readings for the discussion by Brughmans: two book reviews and one review article. A blog posting I like can be found here.
We will discuss quantitative data collection and its network visualization (and I argue its qualitative inflection using metadata) as a process for exploring the interconnectedness of data.
I will show some sample networks created by my students, myself and others, and will discuss how they were constructed, what we might glean from them and what the limitations of them are.
Topics to be included:
-the idea of a network data model
-formats of tabular data (nodes/edges/weights)
-importing data into two different tools: Gephi (standalone) and Palladio (web-based)
-visualizing the network in a graph (overview and preview-Gephi)
-visualizing the network in a graph and on a map (Palladio)
-filtering multidimensional data
-discovering communities in your data
-basics of algorithms and statistics
-exporting different network visualizations
Some sample datasets built by my students will be available for participants to practice both tools. After an initial run through of basic concepts, the session will become hands on.
3 Check out Wikipedia's list of research papers using Gephi to get a feel for the interdisciplinary usages of Gephi.
