Enterprise Software Doesn't Have to Suck: Social Network Analysis using R and Gephis

Enterprise Software Doesn't Have to Suck: Social Network Analysis using R and Gephis
After learning the basics of R, I decided to learn something harder last week. I picked Social Network Analysis (SNA) to learn the concepts of SNA and R. My primary interest in SNA is visual exploration of networks, so I needed to find a tool first. Which tool to use for visual SNA? 1) graphical representation of network 2) visually navigate the graph (zoom in/out, drag) to explore large graphs 3) manipulate the graph (filter nodes, edit/delete/group nodes and same for edges) 4) free, preferably open source. I found out that R has good libraries like SNA (checkout Drew Conway's tutorial) and iGraph (see this tutorial) for social network analysis. So I continued my hunt for a good tool for visual SNA and discovered Gephis, an open source app for visual exploration. WARNING: SNA with Gephis is addictive. After you download Gephi, checkout Gephi quick start guide to get your bearings. Gephi Features Tour from gephi on Vimeo. Web rendition of these graphs is also possible.

Best Infographics Ideas and Free Tools Look at pretty much every blog, professional site and presentation these days, and you will notice that most of them have infographics, which are charts that display a visual image in order to supply data to the user. They are highly functional and often work more effectively than graphs and charts alone. They are also more pleasing to the eye and can break down concepts for easier understanding. But for every good one, there is a bad one that looks cluttered and doesn’t manage to get the point across. That is why people seek out both inspiration and tools to help them make the most out of this valuable resource. Here are some of the best examples and tools to assist you in creating your own. Inspiration Online Piracy With new legislation being argued right now in the Senate to curb piracy, there is a lot of misunderstanding about the topic itself.

Share your images Data Visualization, Design and Information Munging // Martin Krzywinski / Genome Sciences Center Schemaball is a flexible schema visualizer for SQL databases. The purpose of Schemaball is to help visualize the relationships between tables. Tables are related by foreign keys, which are fields which store the value of a record field from another table. Foreign keys create a lookup relationship between two tables. Large schemas can have hundreds of tables and table relationships. Keeping track of them call can be tedious, error-prone and slow down the schema development process. Figure | A MySQL schema of our sequencing LIMS database. Schemaball produces images called schema balls. Schemaball is free software, licensed under GPL. I am not longer actively working on Schemaball. Schemaball was published in SysAdmin Magazine (Krzywinski, M. Ensembl balls!

The Internet map The map of the Internet Like any other map, The Internet map is a scheme displaying objects’ relative position; but unlike real maps (e.g. the map of the Earth) or virtual maps (e.g. the map of Mordor), the objects shown on it are not aligned on a surface. Mathematically speaking, The Internet map is a bi-dimensional presentation of links between websites on the Internet. Every site is a circle on the map, and its size is determined by website traffic, the larger the amount of traffic, the bigger the circle. Users’ switching between websites forms links, and the stronger the link, the closer the websites tend to arrange themselves to each other. Charges and springs To draw an analogy from classical physics, one may say that websites are electrically charged bodies, while links between them are springs. Also, an analogy can be drawn from quantum physics. Anyway, the real algorithm of plotting The Internet map is quite far from the analogies given above. Semantic web The Internet Phenomenon

How to create a social network from a list of emails » Insights - by EYD The question is simple. A typical email in my inbox looks like: - From : George Clooney <g.clooney@como.it>(GC) - To : Clement Levallois (CL) <info@exploreyourdata.com> - Cc : Matt Damon (MD) <md@hollywood.com>, Angelina Jolie (AJ)<angelina@brangelina.com> - Subject : Party - Main text : “Hi Clement! This can be represented visually as a network: Network extracted from one email. Say, you have 1000 emails in your inbox. The short version: here is the workflow I found most convenient to analyze emails from my Yahoo account: 1. - Thunderbird is the email client installed on my computer, where I manage the emails from my Yahoo account. 2. - Gephi is free, open source and available here: www.gephi.org - In Gephi, select the menu “File”, then “Import Spigot” - Select the folder where you exported the eml files in the previous step. - Done! Social network of my personal email communications (visualized with Gephi). The long version: different alternatives available 1. 2. +++ Positive aspects +++

Top wireframing tools - Digital Nation by Claudia Sagripanti on Jun 28, 2012 with 4 Comments I’m involved with Metro Screen’s MetroAppsLab – a mini hackathon/lab for mobile apps development. Oliver Weidlich of Mobile Experience came in and gave a great presentation on wireframing – a how-to and why. 7 reasons to use wireframes in mobile app design To create the skeleton of the applicationTo progress sketches to higher fidelityTo formally plan out the interaction between the screens in more detail and all the functionalityInvestigate different pathsTo use more accurate relative sizingTo use OS elementsCreate assets for usability testing While the benefits of wireframing are clear, the decision on what tool to use is a bit more complicated, depending on the systems and preferences of you and your client. In an informal poll over a strong cup of coffee with several digital agencies, Balsamiq is commonly used, but there are a number of others.
