Gephi, graph exploration and manipulation software Cognitive Surplus by Clay Shirky Following up from my post last week , below is a suggested list of features that should be supported in documents written in scholarly markdown. Please provide feedback via the comments, or by editing the Wiki version I have set up here . Listed are features that go beyond the standard markdown syntax . The goals of scholarly markdown are to support writing of complete scholarly articles, don’t make the syntax more complicated than it is today, and don’t rely on HTML as the fallback mechanism. In practice this means that scholarly markdown should support most, but not all scholarly texts – documents that are heavy in math formulas, have complicated tables, etc. may be better written with LaTeX or Microsoft Word. Cover Page Optional metadata about a document. Typography Scholarly markdown should support superscript and subscript text, and provide an easy way to enter greek letters. Tables Tables should work as anchors (i.e. you can link to them) and table captions should support styled text.
Mapping Social Networks The growth of social networks such as Facebook and MySpace has introduced the idea of the 'social graph' into common parlance. the social graph is Watch this short video describing the proof of concept Vizter social network browser visualisation: Vizter explanatory video. How does vizter allow you to identify friends you have in common with other people? How does vizter help the user identify possible communities in the social graph? If you have a Facebook account, there are several tools that you can use to visualise your friends network on there (requires adding the visulisation as a Facebook application). Here are some of the tools that I'm aware of: Touchgraph frinds'n'photos browser;Nexus social graph browser;FriendwheelFacebook Mutual Friend Network Visualization in FlashFriends visulisation in Many Eyes: this application will mine your friends network and produce a data output that will let you visualise your friends network using the Many Eyes network visualisation tool.

Google’s US headquarters, which hosted the SciFoo technology camp in July. Attendees create the conference schedule on the spot In Oxford, it was shaking hands with legendary videogame designer Peter Molyneux. The occasions were, respectively, the TED Global conference at Oxford in June—where I had been invited to speak about videogames (there’s a online summary of some of my key points here)—and the SciFoo “camp” at Google’s California headquarters in July, where I was representing Prospect. TED—which stands for Technology Entertainment and Design—easily attracts this kind of cynicism. Given all this, accusations of elitism are easy to understand—although these were partly answered in 2006, when Anderson began posting videos of every talk free online. Despite their differences, TED and the Foo camps share crucial similarities. The result is a double shift in awareness.
Gephi: eye-popping, free graph analysis May 16th, 2010 | By Vic | Category: Mindmapping software, Network visualization The latest addition to Mind-Mapping.Org is a mapping application with a formidable collection of exciting and engaging ways of presenting and visually analysing networks – or as maths buffs call them, graphs. Gephi Gephi is an interactive tool for visualizing and exploring networks and complex graphs. ”This is a software for Exploratory Data Analysis, a paradigm that appeared in the Visual Analytics field of research”, they say. It is free open source software. Its purpose is to help data analysts to uncover patterns and anomalies, or faults during data sourcing. It is used for exploratory data analysis; link analysis; social network analysis; and biological network analysis. It employs metrics to analyse connectedness of nodes (degree – power-law, betweenness, closeness), density, path length, diameter, HITS, modularity, clustering coefficient. Vic
Building a Kick-Ass Social Media Dashboard If you are tasked with building a social media dashboard to track your efforts, look no further than this post. I have built many dashboards over the years and as a personal resolution to making my job easier, I decided to cut to the chase and get to the metrics that matter most. That means cutting out the everyday metrics that litter and cloud up the social media manager’s real success story. Now I am not saying that tracking followers, fans, sentiment, etc. is not important, but those are the vanity metrics that tend to give social media a bad name. These type of metrics are great indicators but they don’t really tie back to your business bottom line: driving revenue. With that being said here are the top metrics that I measure here at Marketo on a weekly basis. Referring Traffic from Social Google Analytics is a fantastic way to measure how much traffic is being referred to your website from the various social channels. Conversions from Social This one’s pretty self-explanatory.
Flare | Data Visualization for the Web Mind - Research Upends Traditional Thinking on Study Habits And check out the classroom. Does Junior’s learning style match the new teacher’s approach? Or the school’s philosophy? Such theories have developed in part because of sketchy education research that doesn’t offer clear guidance. Yet there are effective approaches to learning, at least for those who are motivated. The findings can help anyone, from a fourth grader doing long division to a retiree taking on a new language. For instance, instead of sticking to one study location, simply alternating the room where a person studies improves retention. “We have known these principles for some time, and it’s intriguing that schools don’t pick them up, or that people don’t learn them by trial and error,” said Robert A. Take the notion that children have specific learning styles, that some are “visual learners” and others are auditory; some are “left-brain” students, others “right-brain.” Ditto for teaching styles, researchers say.
Content Curation Primer Photo by Stuck in Customs What is Content Curation? Content curation is the process of sorting through the vast amounts of content on the web and presenting it in a meaningful and organized way around a specific theme. Content curation is not about collecting links or being an information pack rat, it is more about putting them into a context with organization, annotation, and presentation. People and organizations are now making and sharing media and content all over the social web. Content Curation Provides Value from the Inside Out What does that mean for nonprofits and the people who work for them? For some staff members, content curation can be professional of learning. The biggest challenge to becoming a content curator is getting past the feeling of “content fried” or so much good content and so little time to digest it.
