DH Press | Digital Humanities Toolkit VisualEyes Mapping a Social Network Today, I am going to show you how to map a social network using NodeXL and Gephi. These are open source and free software packages that you can install on your PC (NodeXL runs only on PC) or Mac (Gephi runs on PC and Mac). There are many reasons you might want to map a social network. So do you want to map a social network all by yourself? Open NodeXL – an add-in that runs in Excel. Go to import > Twitter search network or Twitter users network. For now, I’m just going to ask NodeXL to show me the basic network for the last 200 tweets. Click OK. When the data is imported, it will look something like this: Vertices Tab data in NodeXL A vertex, or node, is created for every user in the network. Now there is a way to visualize this network in NodeXL. Now, open Gephi. Click OK to load your social network. Right now, your network might look like a big hairball. Go to Layout in the lower left-hand corner. Gephi ForceAtlas2 with tuning adjustment Gephi - Nodes resized for in-degree

The 14 Best Data Visualization Tools Nishith Sharma is the co-founder of frrole, a social intelligence startup. Raw data is boring and it’s difficult to make sense of it in its natural form. Add visualization to it and you get something that everybody can easily digest. Not only you can make sense of it faster, but you can also observe interesting patterns that wouldn’t be apparent from looking only at stats. All Killer, No Filler This one’s different, trust us. To make the tedious task of making beautiful charts and maps easier, I’ve made the list of best data visualization tools available for the job. Let’s get started! For Developers D3.js D3.js, short for ‘Data Driven Documents’, is the first name that comes to mind when we think of a Data Visualization Software. It doesn’t ship with pre-built charts out of the box, but has a nice gallery which showcases what’s possible with D3. FusionCharts FusionCharts has probably the most exhaustive collection of charts and maps. Chart.js Google Charts Highcharts Leaflet dygraphs Datawrapper

Recommendations for timeline tools? Oddly enough I'm actually building a timeline tool for the Intro to European History I'm teaching this fall. Basically I'm going to crowdsource a European timeline between 400AD-1700AD in the classroom. I've looked a few things - yes, SIMILE is great and the de facto standard. But as an historian the date handling rubs me the wrong way - perhaps I'm reading the code wrong, but it requires a valid JS Date to work. I want more ambiguity and flexibility when it comes to date parts. I also wanted to place the entire timeline within a custom-designed course website rather than try and handle it with moodle, wordpress, drupal, etc. or even WebCT/Blackboard like 'things' (don't know what else to call them). There are several advantages with this - first is being able to embed a timeline right away using their site and a published googlespreadsheet.

How to Quickly Extract Media from Slide Decks If you’ve ever wanted to quickly extract the media (images, etc.) from a presentation such as PowerPoint or Keynote, there turns out to a pretty simple way to do it. This may well be common knowledge, but, as my friend Merlin Mann likes to say, every day somone’s born who’s never seen The Flintstones. That is, it’s always new to someone–and this was new to me. The key is to recognize that PowerPoint and Keynote files are basically just bundles of other files–that is, they’re fancy ZIP files: So if you want to find an easy way to pull photos, videos and sounds out of a PowerPoint or Keynote file, follow this simple tip:Make a copy of your original file (this way, you don’t risk harming your original). They will be in a folder, like so: Super-handy!

First Reference Ontology for Plant Biology | CyVerse The Planteome Project, an international collaborative effort that is Powered by CyVerse, recently has announced the first full release of their database and ontology browser. The browser serves as a centralized portal where common reference ontologies (structured, controlled vocabularies) for plants are used to annotate gene expression, traits, phenotypes, genomes, and genetic diversity, across a wide range of plant taxa. The Planteome Project is funded by the National Science Foundation and leverages infrastructure provided by CyVerse to develop data standards and reference vocabularies that can be used universally to describe plant gene and phenotype annotation. "Various protein annotation tools hosed by the CyVerse Discovery Environment were used extensively to annotate the proteome of 63 plant species with ontology-based function and phenotype assignments.

Announcing Free Videos and Training Materials From the… — ProPublica Though more than a thousand people have applied to ProPublica’s Data Institute, we’ve only been able to accept about 24 in the two years it’s been running. Faced with such a high demand, we’ve looked for ways to help more journalists trying to learn data journalism and interactive database design. In past years, we’ve put our slides and homework assignments online (here’s 2016 and 2017 ), but we also know how valuable it is to be able to see and hear what’s happening in the classroom. Data Institute Overview Watch the Class of 2017 and ProPublicans talk about how the Institute teaches data journalism. So this year, we recorded videos of five of the lessons from the Data Institute and are releasing them publicly today. These five lessons, which took place over the summer, are from the coding portion of the Institute. We’re also releasing one of our most popular exercises — an educational game.

Tending the Digital Commons: A Small Ethics toward the Future - The Hedgehog Review: Vol. 20 No. 1 (Spring 2018) Facebook is unlikely to shut down tomorrow; nor is Twitter, or Instagram, or any other major social network. But they could. And it would be a good exercise to reflect on the fact that, should any or all of them disappear, no user would have any legal or practical recourse. I started thinking about this situation a few years ago when Tumblr—a platform devoted to a highly streamlined form of blogging, with an emphasis on easy reposting from other accounts—was bought by Yahoo. I was a heavy user of Tumblr at the time, having made thousands of posts, and given the propensity of large tech companies to buy smaller ones and then shut them down, I wondered what would become of my posts if Yahoo decided that Tumblr wasn’t worth the cost of maintaining it. Many personal computers have installed on them a small command-line tool called wget, which allows you to download webpages, or even whole websites, to your machine. Looking to Tolkien Endnotes
