Twitter may be full of jibber-jabber, but that doesn't mean this social networking site can't give us a little insight about what the world is thinking.

Silicon Graphics International, or SGI, has partnered with researchers from the University of Illinois to scan international tweets in a project dubbed the Global Twitter Heartbeat. By using SGI's UV 2000 Big Brain supercomputer, the researchers created real-time heat maps of positive and negative sentiments expressed via Twitter.

This means your angry/excited/nervous/happy tweets are possibly being recorded by an uber-speedy computer in order to stitch together an overall portrait of the Twittersphere's emotions.

So how does it work? "The project analyses every tweet to assign location (not just GPS-tagged tweets, but processing the text of the tweet itself), and tone values and then visualizes the conversation in a heat map infographic that combines and displays tweet location, intensity and tone," SGI's Facebook page reads.

The Global Twitter Heartbeat tracks about 10 percent of the 500 million tweets posted daily -- that's approximately 50 million posts analyzed each day.

Thus far, SGI has created heat maps illustrating people's feelings on Twitter about Hurricane Sandy and the 2012 election night. To see the project in action, watch the clip below, showing how U.S. tweets were affected as the so-called "Frankenstorm" barreled up the East Coast in late October. (Red patches represent negative sentiments. Blue patches are positive.)

Gigaom notes the UV 2 supercomputer that's used to process all of this emotion-filled Twitter data is an "impressive machine with a maximum of 4,096 cores." A press release from SGI also states that the UV 2 could "ingest the entire contents of the U.S. Library of Congress print collection in less than three seconds."

15 Things Twitter Tells Us About Humanity
What We Eat (And It's Not Good)(01 of15)
Open Image Modal
Unfortunately, humanity doesn't eat so well, according to our tweets. The top two food topics last year were the McLobster and Fried Kool-Aid, with Guinness beer not too far behind on the list. For 2012, we expect to see something about the Taco Bell's Dorito Taco.

Floatingsheep geotagged about 10 million tweets (from June 22, 20120 to June 28, 2012) and collected data on posts containing the words "church" and "beer." In the graphic, seen above, the blue patches show places where there was more beer-themed tweeting, while the red spots show tweets mentioning church. Researchers found San Francisco had the most beer-related tweets, Dallas tweeted the most about church, and Los Angeles tweeted the most overall. (credit:Floatingsheep)
When Humanity Is Collectively Happy (Or Grumpy)(03 of15)
Open Image Modal
A report from Cornell University found that, in general, people are grumpy when they first roll out of bed, but they perk up by breakfast time. Throughout the afternoon our moods start to slump again, only to rise around quittin' time (6 p.m). Cornell researchers found these results by weighing positive verses negative tweets posted by more than 2 million people around the world. Interestingly enough, no matter the location, humanity experienced similar rises and falls in mood throughout the day.Graphic from the New York Times (credit:New York Time)

A 2012 study by the Oxford Internet Institute found that out of 4.5 million Twitter posts, the U.S. created 30 percent of the world's tweets, followed by Brazil with 22 percent. The United Kingdom and Indonesia tied for third place with 6 percent each. This graphic illustrates which countries tweet most frequently by giving more active nations a larger portion of space on the "map." (credit:Oxford Internet Institute)

Humanity adores its celebrities, and Twitter is just one of many avenues available for stalking pop stars. Lady Gaga has over 27 million followers on Twitter, meaning that her clan of "little monsters" is larger than the entire state of Texas. Justin Bieber isn't too far behind, recently acquiring 25 million followers and a dance of jubilee from Twitter employees. (credit:AP)
Where We Get Our News(06 of15)

According to a 2012 Pew study, Facebook tends to provide more news from friends and family, while Twitter is more likely to provide journalistic news. And even still, both social media platforms provided less news than originally hypothesized. [Hat Tip: Adam Sherk] (credit:Pew Research Center)

This graphic shows Twitter users who shared at least three New York Times articles from Sept. 14 to Sept. 29 in 2011. The study, from the New England Complex Systems Institute, found that while Twitter brings many users together, we typically connect with like-minded souls online. "A person who is cosmopolitan associates with others who are cosmopolitan, and a US liberal or conservative associates with others who are US liberal or conservative, creating separated social groups with those identities," said Yaneer Bar-Yam, president of NECSI.[Hat Tip: Plectic Ltd] (credit:New England Complex Systems Institute)

The University of Alabama surveyed nearly 8,000 people in 2012, finding that participants over the age of 50 who used Twitter (and Facebook) were one-third less likely to develop symptoms of depression than those not using social media. So maybe it's time to get grandma a Twitter handle? (credit:AP)

Throughout 2011, Rebecca Black's hit (?) "Friday" was the most-discussed song around the Twittersphere. (Our bets are on Carly Rae Jepsen's "Call Me Maybe" for 2012!) "Thor" was also the most tweeted about film, and "Pretty Little Liars" scored the most Twitter clout for television. Within the last week, both "Batman" and "The Dark Knight Rises" have been trending in cities across the U.S. (credit:AP)

According to data from public-relations firm Burson-Marsteller, Fortune Global 100 firms are most active on Twitter, using this platform more than Facebook or YouTube, as of 2012. Maybe a bit surprisingly, this has been the trend since 2010 when Burson-Marsteller first began collecting data. Some of those companies include Exxon, Wal-Mart, GM and Honda. [Hat Tip: All Twitter]
How Sports Bring Tweeps Together(12 of15)

According to Mashable, we tweet heavily during sporting events. In the 2012 European Championship for soccer, there were 15,358 tweets sent per second, and during the last minutes of the 2012 Super Bowl, 10,245 tweets were sent per second. Some close runner-up events were Tim Tebow's overtime touchdown pass on Jan. 8, 2012, as well as two moments from the 2012 FIFA Women's World Cup. (credit:AP)
When We 'Fail Whale' And Have Low Self-Esteem(13 of15)

Just like in the real world, we're always looking for more friends on Twitter. And now, if you're willing to spend a little cash, you can purchase fake followers from online services to bloat your self-esteem. Gizmodo reports that this growing trend isn't technically an illegal Twitter activity, but "[y]ou'll feel disgusted and guilty because you just paid actual money for fake followers on a website, and, man, blech, come on."

That Women Are More Social (And Maybe Becoming More Tech-Savvy)(14 of15)

There are more women than men on Facebook, Twitter, and Pinterest, according to Digital Flash NY, which also means you might see more women entering the tech field soon. "Increasingly the people who are using these social media platforms are women," said Sarah Leary, co-founder of social networking site NextDoor, in an interview with HuffPost. "So it's not surprising that women are increasingly playing a larger role in leading these companies or founding these companies." (credit:Digital Flash NY)
What Topics Send Tweeters Into A Tizzy(15 of15)
Open Image Modal
Hashtags signify Twitter's popular topics, and throughout the last year there was plenty to tweet about. The most used hashtag of 2011 was #egypt, referring to that country's revolution that occurred during the Arab Spring. Charlie Sheen was also having his highly-mediated meltdown around that time, pushing that famous tag he coined, #tigerblood, to second place. Ironic or witty hashtags also made the list, like #idontunderstandwhy and #improudtosay. [Hat Tip: Time] (credit:AP)
