To mark the milestone of each mid-year and end of year I try to take a reflective glance over the previous 6 months period in the data visualisation field and compile a collection of some of the most significant developments. These are the main projects, events, new sites, trends, personalities and general observations that have struck me as being important to help further the development of this field.

At the end of December I published a collection for the last 6 months of 2013 and now I’d like to reflect on the opening 6 months of 2014. I look forward to hearing from you with suggestions for the developments you believe have been most significant. And so, as ever, in no particular order… 1.

Libraries of Mind Maps (updated) Have you noticed the growth of sites featuring libraries of mind maps on the web? Interesting hand made mind maps My focus at is on software-made mind maps – well obviously, I do claim this as “the master list of mind mapping and information management software”, after all. Knowledge management Visual note taking From Japan, but working in English, iroha Note takes a textual approach to visualization – or a visual approach to text notes (take your pick). Its free version feels rather like clustering with Post-it notes, but adds the capability to freely associate notes using visible but subtle linking lines.

The paid-for version, iroha Note+, adds the capability to freely associate notes using visible Continue reading… 15 Effective Tools for Visual Knowledge Management. Since I started my quest a few years ago searching for the ultimate knowledge management tool, I’ve discovered a number of interesting applications that help people efficiently organize information. There certainly is no shortage of solutions for this problem domain. Many tools exist that offer the ability to discover, save, organize, search, and retrieve information. However, I’ve noticed a trend in recent years, and some newer applications are focusing more on the visual representation and relationship of knowledge.

I believe this is in part due to the wider adoption of mind mapping (and concept mapping), and leveraging concepts and advances in the semantic web community. Most traditional personal knowledge management (PKM) or personal information management (PIM) applications offer the same basic set of features: These are essential features, however don’t offer too much to the more visually-inclined knowledge junkies. 15. 14. 13. 12. eyePlorer 11.

Twitter is a great source of information as well as a fantastic communication tool on specific event. In our – academic – world conferences are one of the most commonly occurring events, where a significant degree of communication between participants now happen on Twitter. Last week Dublin was hosting the Research Data Alliance Plenary 3 with over 400 participants. It was organised by Insight Centre and the DRI, as well as other partners from Australia, Europe and US. We were assisting the organising committee with the event’s social media, part of which we demonstrated the top tweeters for each day and also the top tweeters and the top retweeteds for the whole conference.

In this blog post I take you step by step through what I did for (1) computing top tweeters and retweeters, and (2) analysing and visualising the #RDAPlenary social network. Tools used: Getting #RDAPlenary tweets The first step in this journey here is to download tweets from Twitter. 1. 3. 4. Search for #rdaplenary 5. A great free Social Network Analysis Tool.

Networks and Structural Change. “Ultimately if we are to avoid failure in the most critical work of this century, the deepest reaches of our beings must be brought to bear in honestly reevaluating and shifting the most basic structures of our society.” - john a. powell The following is a textual recapturing of a Pecha Kucha-like presentation that I gave at an ARNOVA Pre-Conference Session in Hartford, CT two weeks ago.

This was part of a 3-hour interactive conversation, co-designed and facilitated with Dr. Angela Frusciante of the William Caspar Graustein Memorial Fund, focusing on the power of networks for learning and social change, primarily with academic researchers and philanthropists. At the Interaction Institute for Social Change, we are in agreement with Professor john a. powell when he points to the need to consider and make fundamental structural changes in our country and communities for the causes of greater social justice and sustainability. What is certain is that this is difficult and critical work. Networks as Responsible Structures. Jul/23/14//Curtis Ogden//Networks There is growing awareness that current organizational structures can breed irresponsibility. That is, arrangements are created where people are less able to be responsive in helpful ways. This happens, for example, when accountability is bottlenecked in hierarchies and decision-making is distanced from where the action is most timely and relevant.

In The Responsible Business, Carol Sanford writes about how rigid hierarchy can impede personal and organizational caring. Her commentary could easily apply across sectors and is not necessarily about the lacking emotional realm of organizations, but about their relative disconnectedness from those and that which they are there to serve, and how this has an impact on their long-term health and ability to create value. “The challenge is to replace practices that distance and disconnect with ones that evoke empathy, caring, and creativity. . . .

For me, this is a call to thinking more like a network. Like [3] Early Warning Signs in Social-Ecological Networks. A number of social-ecological systems exhibit complex behaviour associated with nonlinearities, bifurcations, and interaction with stochastic drivers. These systems are often prone to abrupt and unexpected instabilities and state shifts that emerge as a discontinuous response to gradual changes in environmental drivers. Predicting such behaviours is crucial to the prevention of or preparation for unwanted regime shifts. Recent research in ecology has investigated early warning signs that anticipate the divergence of univariate ecosystem dynamics from a stable attractor. To date, leading indicators of instability in systems with multiple interacting components have remained poorly investigated. This is a major limitation in the understanding of the dynamics of complex social-ecological networks.

A Network Way of Working: A Compilation of Considerations about Effectiveness in Networks. “Wrap” by Kevin Dwyer/ “In groups we can do together what we cannot achieve alone. With networks and new computer-based tools now ordinary people can become a group even without the benefit of a corporation or organization.

They can make decisions, own and sell assets, accomplish tasks by exploiting the technology available. They no longer need to rely on a politician to make decisions. They can exercise meaningful power themselves about national, state and local—indeed global—issues. Senior citizens and teenagers use networked handheld computers to police the conditions of urban land use. —Beth Simone Noveck, “A Democracy of Groups”1 “Wherever we look, we see a landscape of movement and complexity, of forms that come and go, of structures that are not from organizational charts or job descriptions, but from impulses arriving out of deep natural processes of growth and of self-renewal. —Margaret J.

Urban Scaling and Its Deviations: Revealing the Structure of Wealth, Innovation and Crime across Cities. With urban population increasing dramatically worldwide, cities are playing an increasingly critical role in human societies and the sustainability of the planet. An obstacle to effective policy is the lack of meaningful urban metrics based on a quantitative understanding of cities. Typically, linear per capita indicators are used to characterize and rank cities. However, these implicitly ignore the fundamental role of nonlinear agglomeration integral to the life history of cities. As such, per capita indicators conflate general nonlinear effects, common to all cities, with local dynamics, specific to each city, failing to provide direct measures of the impact of local events and policy.

Agglomeration nonlinearities are explicitly manifested by the superlinear power law scaling of most urban socioeconomic indicators with population size, all with similar exponents ( 1.15).

Step by Step Social Network Analysis using Gephi: Getting Started | My exploration in data analytics. In continuation to my previous blog post on Social Network Analysis using Gephi, I’m writing this post to explain how do create a very simple social network analysis using Gephi. You can also look at a very good introduction to Gephi written by Martin Grandjean here Goal and Scenario: We have a friends network we want to depict visually how the friends are interconnected with each other. The goal is to understand how to use Gephi Step by step along with having very fundamental understanding of how the data is represented. Pre-Requisites: * You would need the Gephi software which you can download from here. * Data to be imported Step by step Instructions: Step 1: After you install Gephi, you will see a screen like this. Step 2: In this example we are going to import that data from CSV files and we are going to use them for ease of use.

Step 3: Once you Open the Data Laboratory pane now you click Import Spreadsheet. Which will result like the following once you click the finish button. Sources And Methods: The Potential of Social Network Analysis in Intelligence. (In case you missed our most recent article over at e-International Relations or at OODALoop, we are reprinting it here!) The legality of the National Security Agency’s (NSA’s) use of US citizens’ metadata to identify and track foreign intelligence organizations and their operatives is currently a subject of much debate. Less well understood (and consequently routinely misreported) are the capabilities and limitations of social network analysis, the methodology often used to evaluate this metadata.

One of the first causes of confusion is definitional. Social network analysis is often linked to an inappropriate degree with social media. True, social media such as Facebook and Twitter are frequently used as rich data sources for social network analysis, but understanding the importance of networks in the affairs of states has been around at least since Machiavelli.[1] Identifying Key People/Organizations in a Network Figure 3 (Image Source: Melonie Richey) Identifying New Agents Caveat Emptor. 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.

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. 1. 2. 3.
