The integration of sensors with social networks will lead to real-time data and more useful web apps. In recent posts we reviewed an MIT experiment called WikiCity, that gathered real-time location data from mobile phones in Rome and graphically mapped trends from it. We then looked at a more commercial product doing similar real-time location data analysis, called Citysense. That product aims to let users find the most popular night spots in San Francisco and the most efficient ways to get to them. The next stage of projects/products such as Wikicity and Citysense will be to enable users to social...
The traditional notion of hierarchical, top down, government has always been an imperfect match for the decentralized governance system of the US. However, much of what government does requires co-production of policy among agencies that have no formal au
visone is a software for the visual creation, transformation, exploration, analysis and representation of network data, jointly developed at the University of Konstanz and the Karlsruhe Institute of Technology since 2001.
ThinkUp is a free, open source web application that captures your posts, tweets, replies, retweets, friends, followers and links on social networks like Twitter and Facebook.
With ThinkUp, you can store your social activity in a database that you control, making it easy to search, sort, analyze, publish and display activity from your network. All you need is a web server that can run a PHP application.
large groups of people are smarter than an elite few, no matter how brilliant—better at solving problems, fostering innovation, coming to wise decisions, even predicting the future
This article provides an introduction to the use of altmetrics as a tool to assess research impact. In particular, it looks at the evidence behind claims that altmetrics allow the impact of research to be measured in days rather than years. Low correlations between altmetrics and article citations make it doubtful that altmetrics can reliably predict future citations. In addition, there are good reasons to qualify statements that altmetrics measure the wider impact of research on society. Librarians should be careful not to overstate the value of altmetrics when recommending their use as a complement to more traditional measures of research quality.
Entrance into the tools which enables massive feed processing, only thing missing is the realtime semantic annotation of the filtered feeds; Introduces activity streams for me, which seams like an opportunity to set up service networks
Rhe rich get richer, the poor get poorer. The hot get hotter, the cold...disappear from sight! The Matthew Effect is a pretty well known social theory that may help ease your pain as you find yourself isolated from love, peace, and happiness by these phe
SNAPP is a software tool that allows users to visualize the network of interactions resulting from discussion forum posts and replies. The network visualisations of forum interactions provide an opportunity for teachers to rapidly identify patterns of user behaviour – at any stage of course progression. SNAPP has been developed to extract all user interactions from various commercial and open source learning management systems (LMS) such as BlackBoard (including the former WebCT), and Moodle. SNAPP is compatible for both Mac and PC users and operates in Internet Explorer, Firefox and Safari.
Most of the student data generated from Learning Management Systems (LMS) include reports on the number of sessions (log-ins), dwell time (how long the log-in lasted) and number of downloads. This tells us a lot about content retrieval in a transmission model of learning and teaching, but not about how students are interacting with each other in more socio-constructivist practice. Discussion forum activity is a good indicator of student interactions and is systemically captured by most LMS. SNAPP uses information on who posted and replied to whom, and what major discussions were about, and how expansive they were, to analyse the interactions of a forum and display it in a Social Network Diagram. The following figures illustrate how SNAPP re-interprets discussion forum postings into a network diagram.
This purpose of this website is to promote understanding of social network analysis by supporting the teaching of network analysis. It basically contains handouts that explain the concepts and techniques of network analysis.
An excellent article on communities of practice is large enterprise. Haliburton, Whirlpool, Chevron and others. "Organizational network analysis is helping companies share knowledge worldwide, one natural broker at a time. Ask business executives ab
For social networks, the key representational issue is the development of network models whose properties reflect the social reality. Future network models must represent aspects of this reality in a social context, including individual agents’ beliefs
The SNA Package, v1.2 This is a fully documented collection of R routines for social network analysis; utilities included range from hierarchical Bayesian modeling of informant accuracy to logistic network regression (with QAP and CUG tests). Quite a
