Introduction to Network Visualization with GEPHI 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. Because Gephi is an easy access and powerful network analysis tool, here is a tutorial that should allow everyone to make his first experiments. 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.

It is also a general graph visualization tool. Why use it? The STRING web interface, while extensive, is static.
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.
What Does A Map Of The Internet Look Like? Internet-map.net It can be tough to visualize the internet. Web traffic companies like Alexa do a good job of showing the relative ranking of websites, but what about the connections between websites? ToolGoogleNewsScraper Scrapes Google News. Instructions The scraper batch queries news.google.com, outputting a table of returns including URL, title, source, city/country, date and teaser text. Enter a project name for the results file. Cytoscape: Hands-down Winner for Large-scale Graph Visualization I still never cease to be amazed at how wonderful and powerful tools are so often and easily overlooked. The most recent example is Cytoscape, a winner in our recent review of more than 25 tools for large-scale RDF graph visualization. We began this review because the UMBEL subject concept “backbone” ontology will involve literally thousands of concepts. Graph visualization software suitable to very large graphs would aid UMBEL’s construction and refinement. Cytoscape describes itself as a bioinformatics software platform for visualizing molecular interaction networks and integrating these interactions with gene expression profiles and other state data. Cytoscape is partially based on GINY and Piccolo, among other open-source toolkits.
72 Hours of #Gamergate — The Message The Breakdown Most of the posting activity to #Gamergate and #NotYourShield is retweets. (From here on, I’ll refer to both hashtags as just “#Gamergate” for readability’s sake.) Jigsaw - Visual Analytics for Investigative Analysis Summary Investigative analysts and researchers acquire clues and connect small bits of evidence to uncover larger plans, stories, or narratives, and to simply gain a better understanding of the information. Often, the individual bits of evidence are short text documents or spreadsheets, and analysts must examine large collections of such documents in order to "put the pieces together" and formulate a well-supported hypothesis about actions that may occur in the future. As the number of documents to examine rises, it becomes more and more challenging for analysts to understand the data and make judgments about it. We have created Jigsaw, a visual analytics system to help analysts and researchers better explore, analyze, and make sense of such document collections. Our specific objective is to help analysts reach more timely and accurate understandings of the larger stories and important concepts embedded throughout textual reports.
SocialAction SocialAction is a social network analysis tool that integrates visualization and statistics to improve the analytical process. A journal article about SocialAction was recently published in IEEE Computer Graphics and Applications. See the full details in the papers below. SocialAction won a VAST Mini-Challenge award for uncovering hidden structure in social networks over time.
UWGB Commons for the Digital and Public Humanities “Gephi is an open-source software for visualizing and analysing large networks graphs. 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.”
