How hashtags and @ symbols affect language on Twitter

When audience size changes, so do the words


2015-09-09
(Press-News.org) Despite all the shortened words and slang seen on Twitter, it turns out that people follow many of the same communication etiquette rules on social media as they do in speech. Research from the Georgia Institute of Technology shows that when tweeters use hashtags -- a practice that can enable messages to reach more people -- they tend to be more formal and drop the use of abbreviations and emoticons. But when they use the @ symbol to address smaller audiences, they're more likely to use non-standard words such as "nah," "cuz" and "smh." The study also found when people write to someone from the same city, they are even more likely to use non-standard language - often lingo that is specific to that geographical area.

Jacob Eisenstein, an assistant professor in Georgia Tech's School of Interactive Computing, led the research. His team sifted through three years of tweets ¬- a pool that included 114 million geotagged messages from 2.77 million users. He says the study helps explain a puzzle about language in social media.

"Since social media facilitates conversations between people all over the world, we were curious why we still see such a remarkable degree of geographical differentiation in online language," said Eisenstein. "Our research shows that the most geographically differentiated language is more likely to be used in messages that will reach only a local audience, and therefore, will be less likely to spread to other locations."

For example, while the emoticon :) is used everywhere, the alternative ;o is significantly more popular in Los Angeles. Similarly, "mayne," a drawn out way of pronouncing "man," is more likely to be found in Houston than anywhere else.

"People want to show their regional identity or their tech savviness, using Twitter-specific terms, to their close social network ties," said Umashanthi Pavalanathan, a Georgia Tech graduate research scientist who worked on the study.

Eisenstein has looked at popular Twitter word trends and their origins for the last seven years. The more he studies, the more he realizes that Twitter users are smarter than most people give them credit for.

"This research shows that for many people on Twitter, non-standard English is not a question of ability, but of reserving standard English for the right social situations," said Eisenstein. "In this sense, heavy social media users have an especially nuanced understanding of language, since they maintain multiple linguistic systems. They know to use each system when it's socially appropriate."

The paper, "Audience-Modulated Variation in Online Social Media," is published in the journal American Speech.

How can one assess the effectiveness of hypnosis?

2015-09-09
This news release is available in French. Although hypnosis has existed for hundreds of years, today it is still difficult to clearly judge its usefulness in the medical domain. In a report submitted to the French Directorate General for Health, researchers from Inserm led by Bruno Falissard assessed the effectiveness of this complementary medical practice for some of its indications (women's health, digestive ailments, surgery, psychiatry, etc.). The latter illustrates its therapeutic value during anaesthesia, and in the management of irritable bowel syndrome. It also ...

The sweet smell of success

2015-09-09
Catch a whiff of an enchanting perfume, the sweet smell of freshly cut grass, newly baked bread, even the odor of two-stroke engine fumes, and many of us are whisked off to distant places in our memories. Smells trigger immediate emotional responses and marketing departments the world over have exploited this everywhere from supermarkets to car showrooms to help us part with our hard-earned cash. Now, writing in the International Journal of Trade and Global Markets, Shuvam Chatterjee of the Regent Education & Research Foundation, in Dhakuria, India, discusses the concept ...

Mindfulness may make memories less accurate

2015-09-09
Mindfulness meditation is associated with all sorts of benefits to mental and physical well-being, but a new study suggests that it may also come with a particular downside for memory. The findings, published in Psychological Science, a journal of the Association for Psychological Science, show that participants who engaged in a 15-minute mindfulness meditation session were less able to differentiate items they actually encountered from items they only imagined. "Our results highlight an unintended consequence of mindfulness meditation: memories may be less accurate," ...

Making pharmaceuticals that degrade before they can contaminate drinking water

2015-09-09
In recent years, researchers have realized that many products, including pharmaceuticals, have ended up where they're not supposed to be -- in our drinking water. But now scientists have developed a way to make drugs that break down into harmless compounds before they contaminate our taps. Their report appears in ACS' journal Environmental Science & Technology. A wide range of active ingredients originating from pesticides, shampoos, lotions, cosmetics, disinfectants and drugs get washed into sewage systems or rivers and streams, ending up in our tap water. Scientists ...

New Ebola test could help curb disease spread

2015-09-09
Amsterdam, September 9, 2015 - A new Ebola test that uses magnetic nanoparticles could help curb the spread of the disease in western Africa. Research published in Biosensors and Bioelectronics shows that the new test is 100 times more sensitive than the current test, and easier to use. Because of this, the new test makes it easier and cheaper to diagnose cases, enabling healthcare workers to isolate patients and prevent the spread of Ebola. The authors of the study, from the Chinese Academy of Sciences, say their new technology could be applied to the detection of any ...

Alzheimer's puts heavier economic burden on women

2015-09-09
WASHINGTON, DC (September 9, 2015) -- Women are not only at greater risk of developing Alzheimer's disease (AD) when compared to men; per capita, they also bear six times the cost of AD care that men do, reports a study published today in the journal Women's Health Issues. Authors Zhou Yang of Emory University's Rollins School of Public Health and Allan Levey of the Emory University School of Medicine used a lifetime perspective to calculate AD costs to women and men based on three factors: the probability of developing AD, the disease's duration, and the required formal ...

Game-changing technology enables faster, cheaper gene editing

2015-09-09
Within the past few years, a new technology has made altering genes in plants and animals much easier than before. The tool, called CRISPR/Cas9 or just CRISPR, has spurred a flurry of research that could one day lead to hardier crops and livestock, as well as innovative biomedicines. But along with potential benefits, it raises red flags, according to an article in Chemical & Engineering News (C&EN), the weekly newsmagazine of the American Chemical Society. Ann M. Thayer, a senior correspondent at C&EN, notes that scientists have long had the ability to remove, repair ...

New wearable technology can sense appliance use, help track carbon footprint

New wearable technology can sense appliance use, help track carbon footprint
2015-09-09
In today's smart home, technologies can track how much energy a particular appliance like a refrigerator or television or hair dryer is gobbling up. What they don't typically show is which person in the house actually flicked the switch. A new wearable technology developed at the University of Washington called MagnifiSense can sense what devices and vehicles the user interacts with throughout the day, which can help track that individual's carbon footprint, enable smart home applications or even assist with elder care. In a study to be presented this week at the ...

Parsing photons in the infrared, UCI-led astronomers uncover signs of earliest galaxies

2015-09-09
Irvine, Calif., Sept. 7, 2015 - Astronomers from the University of California, Irvine and Baltimore's Space Telescope Science Institute have generated the most accurate statistical description yet of faint, early galaxies as they existed in the universe 500 million years after the Big Bang. In a research paper published today in Nature Communications, the team describes its use of a new statistical method to analyze Hubble Space Telescope data captured during lengthy sky surveys. The method enabled the scientists to parse out signals from the noise in Hubble's deep-sky ...

24-hour OBs, midwives lead to less C-sections

2015-09-09
Privately insured pregnant women are less likely to have C-sections when their regular care includes midwives and 24-hour obstetrician coverage, according to a study by researchers at UC San Francisco and Marin General Hospital. The study published online in Obstetrics & Gynecology, on Sept. 8, compared the number of C-sections among women with private insurance, before and after an overhaul of staff practices at Marin General Hospital. Prior to April 2011, private patients at this community hospital in Northern California were managed under a conventional model, in ...
