How Twitter Could Unleash World Peace
Researchers from Britain, Korea, and Germany have determined that the amount of fresh information you get on Twitter is less a matter of what you follow than whom—and who follows you
By Bobbie Johnson
On certain days, Twitter can feel like the world"s biggest, fastest echo chamber. Since we tend to follow people who are similar to us, we often see our own views reflected back—meaning a gloomy cloud of irritation can rapidly swirl into a cyclone of outrage as we hear from other people who feel as we do. A group of computer scientists have discovered that the opposite may also be true. Can Twitter be part of the solution, not merely part of the problem?
In a study to be presented at a conference in July, a team of researchers from the U.K."s University of Cambridge, Korea"s Graduate School of cultural Technology-KAIST, and Germany"s Max Planck Institute for Software Systems show how Twitter can provide users greater access to more varied political viewpoints and media sources than they might otherwise get.
The paper, called "The Media Landscape in Twitter(http://www.cl.cam.ac.uk/~jac22/out/twitter-diverse.pdf)," explains how the team made surprising discoveries when they looked into the site"s usage patterns. First they looked at who follows whom and discovered that Twitter is a highly politicized space. Then they examined patterns of tweeting and retweeting to try to understand how people receive information on Twitter—and what they might see. Their conclusion: Although Twitter is a pretty partisan space, it can offer unprecedented opportunities to break down the barriers that plague local, national, and international politics.
How? Through retweets and interaction—what the authors call "indirect media exposure." As they put it, this "expands the political diversity of news to which users are exposed to a surprising extent, increasing the range by between 60 percent and 98 percent. These results are valuable because they have not been readily available to traditional media and they can help predict how we will read news and how publishers will interact with us in the future."
If you"re interested in the way Twitter works, I recommend reading the paper, which isn"t very long. Meanwhile, let"s boil it down to a few key pieces of data and see what lessons they can teach.
Most Twitter users are political. Just over half (50.8 percent) of all Twitter users studied showed a distinct political bias in the media outlets and individuals they followed. Most of those lean to the left of the political spectrum, accounting for 62 percent of users who demonstrated some bias. Thirty-seven percent were doggedly centrist. Just 1 percent of Twitter users who showed a political preference were right-wing.
Here are a couple of caveats about reading too much into the sharp divide the authors found. Given that Twitter"s user base is younger and more metropolitan than the societal norm, it"s not surprising that it"s weighted to the left. It"s worth noting that this study was undertaken more than a year ago; since then, Twitter has grown dramatically, while global politics have largely skewed back toward the right. Twitter"s user base today might reflect a more-balanced political picture. Either way, there"s a big split.
Twitter has secondary and tertiary benefits. Most organizations comprehend Twitter in simple terms: More followers means more exposure. But the study shows that it"s not just about those you follow, but those your followers follow—essentially the people in your extended network. The network offers a number of routes for information from fresh sources to get to you. According to the study, some 80 percent of users choose to follow at least 10 media sources, but they are exposed to between 6 and 10 times as many media sources through their friends.
People outweigh brands. Many of the biggest Twitter accounts are big media brands such as CNN (TWX) and Time, but the study suggests that Twitter"s active users tend to prefer individuals over outlets. So while the average follower of @NYTimes (NYT) has six followers apiece, individual journalists have followers who boast a median following count of around 100. That gives individual journalists—who are, the study says, more likely to link to a multiplicity of sources—a much wider, more influential network of connections.
The inference is that the personal touch of a journalist is more important than the lofty, impersonal tone of publications that largely act as promotion channels for their content. It"s a discovery that reminded me of Twitter"s recent blog post on the science of the hashtag, which found that hashtags explode in usage when they are picked up by individuals with the most dedicated—not necessarily the largest—followings.
Active users access a wider range of views. The researchers say that indirect exposure expands political diversity by a "significant amount," despite other studies showing a tendency for social networks to do the opposite. "Other studies have found a stronger tendency of homophily; blogs of different political views rarely linked to each other," they point out. "One possible reason is that a Twitter network encompasses several different relationships—from shared interest, to familial ties, friends, and acquaintances—so political similarity doesn"t necessarily exist in all such ties."
This is not to say that Twitter"s creators should be preparing a Nobel Prize-winning speech. Far from it: The influence of its diversity is unknown. It could be that many people who see messages they disagree with simply change their behavior to screen out such material in future. But it shows that there is a potential to do something positive at Twitter. It"s clear there"s much work to be done. The researchers say they want to investigate a number of areas they"ve uncovered, having provided important insights at a time when politics seem more fractious and divided than ever.

Interdisciplinary Research on World Environmental Problems with Humanities
KAIST’s Professor Michael Pak (department of Humanities and Social Sciences) has published a paper in ‘Environmental Science and Technology, ES&T’ and was made Lead Feature.
His was the only paper published with a humanities background and his topic of discussion was ‘Environmentalism Then and Now: From Fears to Opportunities, 1970-2010’ in which he discussed the history of pro-environment activities, the patterns it showed, and its outlook.
Professor Park noted that the problems and concerns over the environment is not a recent phenomenon. It took over 50 years for the environmental problems to resurface after being the ‘hot issue’ of the time during the industrial revolution in the 19th century.
Professor Park deduced that there is a clear historical pattern.
Professor Park insisted that the two areas of Environmental Research ‘Global Warming’ and ‘Change in Weather’. Especially because these two areas are rife with uncertainty as it is, and making policies based on inaccurate information is taking a gamble.
Professor Park majored in history in UC Berkeley, received his masters’ and doctorate at Harvard University and was the professor at Massachusetts College of Art and Design before coming to KAIST at 2008.

A KAIST student earns 500 million won with "Virtual Finger" idea.
A student’s small idea was transformed into a viable technology, yielding 500 million won through the technology transfer.
In a mobile environment, it is difficult to hold the device and use its multi touch function, at the same time. A doctorate candidate of the KAIST Cultural Technology Graduate School, Hwang Sung Jae (28 years old), identified the inconvenience that it is hard to see the full screen of a mobile phone while manipulating it, and he invented a helper called “Virtual Thumb.”
The thumb allows a user to use only one finger to perform tasks that require the movements of several fingers like punching, zooming in/out and rotating the screen. When the user touches a screen, a virtual finger is created on the other side of the screen and mimics the motion of the user’s touching.
The ‘virtual Finger’ technology is based on the idea that came in second in the 2009 Korea Invention Patent Competition hosted by the Korea Intellectual Property Office and can be applied to any device that has a touch-based system which spans from a TV remote controller to a Tablet PC’s.
The Office of University and Industry Cooperation, KAIST, facilitated to turn Hwang’s idea into commercialization, and on October 18, Victronix, a Korean mobile phone manufacturer, bought a patent right for the technology at 500 million won.

KAIST Student Earns Five Hundred Million Won on Virtual Thumb Idea.
Hwang Sung Jae, a PhD candidate at the Graduate School of Cultural Technology, developed a Virtual Thumb technology that allows multi-touch functions with one hand. Hwang got his idea from limitations of current mobile phones, including the covering of the screen by the use of fingers and the fact that multi-touch functions are hard to perform with one hand holding the mobile phone.
With this technology, one finger gives the same effect of using both fingers to perform a function. Using the Virtual Thumb that appears on a point corresponding to the point of physical touch, movements corresponding to actual touch movements are mimed to allow zooming in/out and various rotation angle based functions.
In addition, in situations where object rotation is unnecessary, many functions are subjectively matched using the change in rotational angle. It allows for various commands are simultaneously executed without activating a separate commanding menu. In the case of the zoom in command at a corner region, the corner can be zoomed in without moving the object to the center of the screen.
The Virtual Thumb technology can be applied as a middleware on touch-based apparatus including TV remote controls, eBook, mobile phones, tablet PCs, navigation systems and educational apparatus.
“I am honored that a small idea that developed during research can be developed into an actual commercialized technology,” said Hwang. “I will become a researcher who will add to the academic and industrial fields through creative research in the future.”

KAIST Animation 'Captain Banana' To Be Shown at SIGGRAPH Asia 2010
‘Captain Banana,’ a short animation created by researchers of Associate Professor Junyong Noh’s Visual Media Laboratory and current students of the Graduate School of Culture Technology (CT), will be shown at SIGGRAPH Asia 2010 this December 15th to 18th.
Following last year’s screening of ‘Taming the Cat’ at the SIGGRAPH CG Animation Festival in the United States, Professor Noh’s work has been chosen to be shown at global CG animation festivals for two years in a row.
Since the first exhibition by ACM in 1974, SIGGRAPH has become a global computer graphic festival that has a strong influence on the global CG and interactive technology industry. The Asian version of SIGGRAPH, SIGGRAPH Asia has been held annually at Singapore in 2008 and Yokohama, Japan in 2009. This year’s SIGGRAPH Asia will be held at COEX in Seoul from December 15th to 18th.
‘Captain Banana’ is a five minute film about Captain Banana, who explains recent issues over sex including unwanted pregnancies, the eradication of abortions and prevention of AIDS through a series of funny situations with his ten little friends.
“Along with being chosen for screening at global CG animation festivals two years in a row, this year’s selection is significant in that the VM Lab has increased the efficiency of the creating process by using technology we have developed on our own,” said Professor Noh.
The production period took approximate five months with approximately 20 current students of CT and five researchers of the Visual Media Lab.

KAIST offers a new course on three-dimensional movies.
Registration for the class ends on February 18, 2010.
The Graduate School of Culture Technology (GSCT) at KAIST created a special class entitled “Master Class for Three-Dimensional (3D) Film Production.” Applications for the class will be accepted by Thursday, February 18, 2010.
The latest 3D movie, AVATAR, has become very popular upon its release in late 2009: An overwhelming visual and sensory experience provided by a 3D technology gave viewers real life feelings about a virtual reality built in the movie. People can almost reach out and touch an explosion, components of machines, and aliens appeared on the screen.
“In response to growing interests in 3D movies, KAIST GSCT established a special session to teach students an overall process of 3D film production,” said Kwang-Yeon Won, Dean of GSTC. He also stressed that the 3D technology would serve as catalysts in developing the next generation of visual industry in the 21st century.
“We have actively engaged in the development of 3D core technology and application contents. This class will be the first of our initiatives to launch a series of educational programs on 3D technology.”
The class offers a complete road of 3D film production: an overview of stereography for 3D movies from planning, shooting, to post production. Many of film professionals (i.e., Director Yang-Hyun Choi and Shooting Director Byung-Il Kim), who are currently working in the field, will join the class so that students can have an opportunity to learn all ends of 3D film industry, both in terms of theoretical knowledge and practical work experience.
The class is open to undergraduate/graduate students and to the public. For details, please refer to the website of http://ct.kaist.ac.kr/stereoclass2010 or call at 02-380-3698 (Industry-University Research Collaboration Center at KAIST Graduate School of Culture Technology).
