2013 Getty Images If you are one of Twitter’s 241 million active users, there’s one constant to the network: it can be incredibly vast and remarkably small.
The social network teems with an enormously diverse and intertwined group of people — from journalists and activists to government officials and college students — chatting on a range of topics in an often overwhelming ecosystem of cliques, crews and mobs. Finally, Twitter has something like a map. A report from the Pew Research Internet Project highlights how researchers have developed six general models of the types of communities on the eight-year-old social network. As Pew's researchers see it, these visualizations represent the clearest picture of what civil society looks like when translated into the sprawling wasteland of the Internet. The Pew Research Center normally produces public opinion polls describing American attitudes toward the Internet.

What you’ll Need: Copyright Images: How to Avoid and Curate Safely. What you should know about Image Licenses Today’s web technology makes it very simple to download any image that you’d like, and then use that image (or a thumbnail) in your own content.

At the same time, some of those images have copyrights and licensing fees associated with them.

Not only may they ask you to stop using the images in question, they may attempt to charge retroactive usage fees. There are two ways to proactively protect yourself in such scenarios: Pay royalties for any applicable images you use so that all the images you use are using it in a licensed manner.Avoid copyrighted images. For most cost-conscious curators, the second option is more amenable.

In my last two posts I introduced the Econsultancy Twitter network, and wrote about how we could use social network analysis to identify influencers and innovators in this community.
In this post I'll look at how mapping a network can help us identify sub-groups in the community and target content to them more effectively. Detecting sub-groups in the Econsultancy Twitter network The most famous example of a sharply divided online community is Lada Adamic's analysis of US political bloggers during the 2004 presidential election. Her visualisation clearly shows Democrat (blue) and Republican (red) camps, with very little communication between them. Predictive Policing: Preventing Crime with Data and Analytics.

A Brief Introduction to Social Network Analysis by Orgnet, LLC. Social network analysis [SNA] is the mapping and measuring of relationships and flows between people, groups, organizations, computers, URLs, and other connected information/knowledge entities. The nodes in the network are the people and groups while the links show relationships or flows between the nodes. SNA provides both a visual and a mathematical analysis of human relationships. Management consultants use this methodology with their business clients and call it Organizational Network Analysis [ONA].
ONA allows you to x-ray your organization and reveal the managerial nervous system that connects everything. Immersion: a people-centric view of your email life. Your social networks and the secret story of metadata. Researchers at MIT’s Media Lab have created an application called Immersion, which uses your email to display all of the people you communicate with in a highly visual way. Although it was designed primarily as a way of illustrating a person’s connections and social networks, it has served to highlight the amount of information that is encoded in communication metadata and what can be done with that data without even needing the actual content of emails. This is especially relevant at the moment with the revelations that the US secret service has been engaged in widespread surveillance using email and other personal data sourced from companies such as Google, Apple, Facebook and Microsoft.
Email metadata refers to information such as the sender and recipients of an email. On its own, this information may not be particularly very interesting, especially if as in my case, it is one of 53,129 emails that is in my work Gmail account.
