TagCrowd

From the TagCrowd blog

TagCrowd is a web application for visualizing word frequencies in any user-supplied text by creating what is popularly known as a tag cloud.

Today, tag clouds are primarily used for navigation and visualization on websites that employ user-generated metadata (tags) as a categorization scheme. (Flickr is a good example.)

TagCrowd is trying to do something different.

When we look at a tag cloud, we see not only a richly informative, beautiful image that communicates much in a single glance. We see a whole new approach to text.

Potential uses for tag clouds extend far outside the online realm: as topic summaries for written works, as name tags for conferences, as resumes in a single glance, as analyses for survey data, as visual poetry; the list goes on.

In the future, TagCrowd will develop into a suite of experimental tools and tutorials that empower social and collaborative uses for tag clouds and related visualizations.

Social network vizster

Re-blogged from InfoAesthetics

vizster.jpg

Vizter is a sophisticated social network data visualization system that end-users of social networking services can use to facilitate discovery & increased awareness of their online community. vizster presents social networks using a simple network node-link representation, where nodes represent members of the system & links represent the articulated 'friendship' links between them. network members are depicted using both their self-provided name & a representative image. the networks are presented as 'egocentric' networks, consisting of an individual & their immediate friends. users can expand the display by selecting nodes to make visible others’ immediate friends as well. in addition, inferred community groupings of two or more nodes are visibly represented as 'blobs' surrounding community members, taking advantage of low spatial frequencies to make community structures apparent.

Does "collective intelligence" exist?

Via KurzweilAI.net 

Can people and computers be connected so that - collectively - they act more intelligently than any individuals, groups, or computers have ever done before?

Researchers at MIT Center for Collective Intelligence will address this question in a research project that will involve a group of thousands of people collectively writing a business book "Wikipedia style".  

MIT researchers also expect to have projects on prediction markets, global climate change, and several other topics.

From the press release 

“CCI is trying to look over the horizon to see what will be common five, 10, or 20 years from now. Google, Wikipedia, Linux, and e-Bay are examples that show something interesting and important is already happening. Such examples are not the end of the story, but just the beginning.  And I hope that our work can help people understand and take advantage of these exciting possibilities"

Visualization of literature trends

Via infosthetics

 

scientificliteraturetrends.jpg

 

CiteSpace is a network data visualization technique that facilitates the detection of emerging trends and transient patterns in scientific literature.

From Infoesthetics:

CiteSpace is based on 2 concepts: "research fronts", defined as an emergent grouping of concepts & underlying research issues & "intellectual base", the network of citations & co-citations of a research front in scientific literature. the size of a node is proportional to the normalized citation counts in the latest time interval. The label size of each node is proportional to citations of the article, thus larger nodes also have larger-sized labels. the user can enlarge font sizes at will, & both the width & the length of a link are proportional to the corresponding cocitation coefficient. the color of a link indicates the earliest appearance time of the link with reference to chosen thresholds. current applications show complex patterns regarding mass extinction research & terrorism research.

Whole-brain connectivity diagrams

Via BrainTechSci 

In a previous post I covered BrainMaps, the interactive zoomable high-resolution diagram for whole-brain connectivity. Now the project provides a powerful new feature, the interactive visualization of brain connectivity in 3D.

From the download page

Welcome to nodes3D, a 3D graph visualization program written by Issac Trotts in consultation with Shawn Mikula, in the labs of Edward G. Jones. On startup, nodes3d will download a graph of gross neuroanatomical connectivity from the MySQL database at brainmaps.org. Future versions will probably support loading of graphs from files or other databases

Urban Tapestries

From the project website 
 
medium_gmaps_main.2.jpg
 
 
Urban Tapestries is an experimental software platform for knowledge mapping and sharing – public authoring. It combines mobile and internet technologies with geographic information systems to allow people to build relationships between places and to associate stories, information, pictures, sounds and videos with them.

Urban Tapestries aims to enable people to become authors of the environment around them – Mass Observation for the 21st Century. Like the founders of Mass Observation in the 1930s, we are interested creating opportunities for an "anthropology of ourselves" – adopting and adapting new and emerging technologies for creating and sharing everyday knowledge and experience; building up organic, collective memories that trace and embellish different kinds of relationships across places, time and communities.

It is part of an ongoing research programme of experiments with local groups and communities called Social Tapestries.

Brain box

BBC News, july 17, 2006

BBC reports that researchers from University of Manchester are developing a new biologically-inspired computer, which mimics the complex interactions between brain neurons.

The computer will be designed with the aim of modelling large numbers of neurons in real time and to track patterns of neural spikes as they occur in the brain. It will be built using large numbers of simple microprocessors designed to interact like the networks of neurons found in the brain. The aim will be to place dozens of microprocessors on single silicon chip reducing the cost and power consumption of the computer.

CIO: Visualization of Internet Ownership

internet-backbone.gif

 
From CIO: What is this ball of colors? It is the North American Internet, or more specifically a map of just about every router on the North American backbone, (there are 134,855 of them for those who are counting). The colors represent who each router is registered to. Red is Verizon; blue AT&T; yellow Qwest; green is major backbone players like Level 3 and Sprint Nextel; black is the entire cable industry put together; and gray is everyone else, from small telecommunications companies to large international players who only have a small presence in the U.S. If you click on the map it will take you to much bigger version complete with labels that tell you the address of many of the routers

Near-Field Intrabody Communication

Via Networked performance 

"As electronic devices become smaller, lower in power requirements, and less expensive, we have begun to adorn our bodies with personal information and communication appliances. Such devices include cellular phones, Personal Digital Assistants (PDAS), pocket video games, and pagers. Currently there is no method for these devices to share data. networking these devices can reduce functional i/o redundancies and allow new conveniences and services. The concept of Personal Area Networks (PANS) is presented to demonstrate how electronic devices on and near the human body can exchange digital information by capacitively coupling picoamp currents through the body. A low-frequency carrier (less than 1 megahertz) is used so no energy is propagated, minimizing remote eavesdropping and interference by neighboring pans. A prototype pan system allows users to exchange electronic business cards by shaking hands."

Small-World Human Brain Functional Network

A Resilient, Low-Frequency, Small-World Human Brain Functional Network with Highly Connected Association Cortical Hubs

J. Neurosci. 2006; 26: 63-72. 

Sophie Achard, Raymond Salvador, Brandon Whitcher, John Suckling, and Ed Bullmore

Small-world properties have been demonstrated for many complex networks. Here, we applied the discrete wavelet transform to functional magnetic resonance imaging (fMRI) time series, acquired from healthy volunteers in the resting state, to estimate frequency-dependent correlation matrices characterizing functional connectivity between 90 cortical and subcortical regions. After thresholding the wavelet correlation matrices to create undirected graphs of brain functional networks, we found a small-world topology of sparse connections most salient in the low-frequency interval 0.03–0.06 Hz. Global mean path length (2.49) was approximately equivalent to a comparable random network, whereas clustering (0.53) was two times greater; similar parameters have been reported for the network of anatomical connections in the macaque cortex. The human functional network was dominated by a neocortical core of highly connected hubs and had an exponentially truncated power law degree distribution. Hubs included recently evolved regions of the heteromodal association cortex, with long-distance connections to other regions, and more cliquishly connected regions of the unimodal association and primary cortices; paralimbic and limbic regions were topologically more peripheral. The network was more resilient to targeted attack on its hubs than a comparable scale-free network, but about equally resilient to random error. We conclude that correlated, low-frequency oscillations in human fMRI data have a small-world architecture that probably reflects underlying anatomical connectivity of the cortex. Because the major hubs of this network are critical for cognition, its slow dynamics could provide a physiological substrate for segregated and distributed information processing.

View of cell-phone activity in Graz

via Future Feeder

Digital Derive is a platform developed senseable city lab that allows to visualize the volume & geographic source of cell phone usage in Graz, showing a visual conceptual layer in the use & experience of the city.

From the lab web site:

Digital Derive harnesses the potential of mobile phones as an affordable, ready-made and ubiquitous medium that allows the city to be sensed and displayed in real-time as a complex, pulsating entity. Because it is possible to simultaneously 'ping' the cell phones of thousands of users - thereby establishing their precise location in space at a given moment in time - these devices can be used as a highly dynamic tracking tool that describes how the city is used and transformed by its citizens. The polis is thus interpreted as a shifting entity formed by webs of human interactions in space-time, rather than simply as a fixed, physical environment. Digital Derive provides a platform upon which the contemporary city can register the flux and traces its self-constructing and open-ended nature. Previous initiatives, notably Laura Kurgan's 'You Are Here: Museu' (1996) and the Waag Society's 'Amsterdam Real-Time' (2002) initiated this process by exploring the qualities and potential of GPS technology. Digital Derive builds on an expands these efforts by using cell phone technology, for the first time, to radically increase the interactive capacity and number of users involved in the mapping of the city. Digital Derive (re)presents the city displayed simultaneously in the Kunsthaus Graz and in a publicly accessible website.

Social Networks as Health Feedback Displays

In this paper published on September/October issue of IEEE Pervasive Computing Journal Margaret E. Morris describes how social-networking and pervasive computing technologies can be used to help reduce feelings of social isolation and depression in elderly individuals. In this approach, sensor data measuring phone calls and visits are used to derive public displays of social interactions with relatives and friends, which they introduced into select elders’ homes. According to Morris and colleagues, as people see their social interactions illustrated in these feedback displays, their feeling of social isolation is reduced.

Margaret E. Morris. "Social Networks as Health Feedback Displays," IEEE Pervasive Computing Journal, vol. 9, no. 5, pp. 29-37, September/October 2005.

Abstract

Social networks have thus far served primarily as analytic tools for social scientists. Leveraging pervasive computing, this new research transforms social-network models into behavioral feedback displays. These ambient displays, which reflect data on remote and face-to-face interaction gathered by wireless sensor networks, were intended to raise awareness of social connectedness as a dynamic and controllable aspect of well-being. An interdisciplinary health technology research group at Intel recently developed and tested prototypes in the homes of older adults and their caregivers. This article reviews the psychological rationale for the project and highlights some reactions of participants to the displays.
