Techniques and Tools: How To Visualize Your Network

What I really enjoy about events that Aspiration convenes is that they allow the time and depth for practitioners to share knowledge and strengthen connections. The participants are the content – and the design of getting participants into small group discussions where we can discuss topics related to our work that we are passionate about and want to explore and learn. These discussions are not lectures or traditional panels and are participant driven.

DM (2008) The application of network analysis to ancient transport geography: A case study of Roman Baetica

This is not due to the completeness of its record (for it is not), but because it provides a remarkable breadth of pertinent data (Sillières 1990, 9-16). This paper, loosely based on a seminar hosted by the Digital Classicist at King’s College London, will briefly discuss the results of applying some as-yet relatively uncommon techniques to the archaeology and documentary record of transport in the area. It will then go on to tackle some more general issues in creating maps of movement in the past, concluding that there is still much theoretical work to be done, but that the potential for discovering new patterns in old data is great, and indeed, ever growing. § 2 The main concept that will be explored is that of a Node Network, an abstract model of the interactions between spatially separate locations.

Get Your Data into Gephi: A Quick and Basic Tutorial. If you’re interested in learning more about information visualization by trying out some yourself, here’s a quick tutorial on how to get a very basic dataset showing character relationships from a piece of literature into Gephi!

Basic Gephi Dataset Creation In the Bloomsday project, we recorded data about what character interacted with which other characters, and used a scale of 1-7 to indicate the perceived intimacy of those interactions (e.g. from one person thinking of another person, to an involved conversation between two people). Here’s an example of these two columns in the Bloomsday visualization dataset: Source Target Weight John Jim 2 John Jane 1 Jane Jim 2.

SoNIA - Social Network Image Animator

SoNIA is a Java-based package for visualizing dynamic or longitudinal "network" data. By dynamic, we mean that in addition to information about the relations (ties) between various entities (actors, nodes) there is also information about when these relations occur, or at least the relative order in which they occur. Our intention for SoNIA is to read-in dynamic network information from various formats, aid the user in constructing "meaningful" layouts, and export the resulting images or "movies" of the network, along with information about the techniques and parameter settings used to construct the layouts, and some form of statistic indicating the "accuracy" or degree of distortion present in the layout.

This is all somewhat ambitious, but not impossible. What else is SoNIA for? In addition, we hope that SoNIA will have other uses. Another mode of use that SoNIA supports is that of a "browser" for time-based network data. Complex Adaptive Systems Modeling - a SpringerOpen journal. Social Networks - ScienceDirect.com.

Gephi uses a 3D render engine to display graphs in real-time and speed up the exploration. You can use it to explore, analyse, spatialise, filter, cluterize, manipulate and export all types of graphs.” Gephi is a program downloaded from the internet, and can be found here. First your group should decide what instances/variable/interactions you will be collecting information about. This could be who talks to who in the novel, who directly interacts with each other, or who as a character is given direct speech rather than internal dialogue. Free Tools to Visualize Your Data. Data visualization has grown in popularity as datasets have become larger and tools have become more user-friendly.

This area is eagerly being explored by researchers in a variety of disciplines. Although many people think of numbers when they consider types of data, data comes in many forms–including text! In fact, for many researchers, especially those in the humanities or social sciences, text is their primary data source. This example of a network visualization could be created using a tool like Gephi or Sci2. Image: Clickstream Data Yields High-Resolution Maps of Science. Complex Adaptive Systems Modeling - a SpringerOpen journal. Tools - WikiViz. Social Network Analysis: A Systematic Approach for Investigating. Social network analysis (SNA) is often confused with social networking sites, such as Facebook, when in fact, SNA is an analytical tool that can be used to map and measure social relations.

Through quantitative metrics and robust visual displays, police can use SNA to discover, analyze, and visualize the social networks of criminal suspects. SNA, a social science methodology, serves as a valuable tool for law enforcement. While technologically sophisticated, SNA proves easy to employ. Using available data, police departments structure the examination of an offender’s social network in ways not previously possible.

Introduction to Network Visualization with GEPHI. New tutorial available! A completely new version of this tutorial has been published, with 2 complete and complementary datasets to learn and explore many basic and advanced features of Gephi: To the new tutorial Gephi workshop at University of Bern (photo Radu Suciu) Social Network Analysis is a lens, a way of looking at reality. (Claire Lemercier at Swiss Digital Humanities Summer School 2013) Network Analysis appears to be an interesting tool to give the researcher the ability to see its data from a new angle.

I propose below, after a short introduction about the basis of SNA and some examples which shows the potential of this tool, a transcript of tutorial given during a workshop of the first Digital Humanities summer school in Switzerland (June 28. 2013), and kept up to date. 1.

GraphChi can run very large graph computations on just a single machine, by using a novel algorithm for processing the graph from disk (SSD or hard drive). Programs for GraphChi are written in similar vertex-centric model as GraphLab. GraphChi runs vertex-centric programs asynchronously (i.e changes written to edges are immediately visible to subsequent computation), and in parallel.
