Bits Blog: Google Search Terms Can Predict Stock Market, Study Finds
The terms people search for on Google have been used to forecast how many Americans have the flu, travel plans and the price for which cars sell. Now a scientific study shows that Google search can be used to predict the stock market.
Using Google Trends, a service that shows the popularity of search terms, researchers from Warwick Business School in England and Boston University’s department of physics found that the type of terms people search Google for on a given week can predict whether the Dow Jones industrial average will rise or fall the following week.
The study, titled “Quantifying Trading Behavior in Financial Markets Using Google Trends,” was published Thursday in Nature’s Scientific Reports.
The researchers tracked 98 search terms from Google Trends between 2004 and 2011. These included investment-related words, like debt, stocks, portfolio, unemployment and markets, and non-investment terms, including lifestyle, arts, happy, war, conflict and politics.
One of the leading search terms used to predict the markets was the word “debt” — an increase in such searches heralded a sell-off of stocks. A decrease in searches found the market rose slightly the following week.
But the results do not take into account volatile markets where a big sell-off can force investors to abandon ship sooner than they anticipated.
And sometimes Google Trends can give scientists inaccurate information when the proper context is not applied. For example, earlier this year Google Flu Trends said it believed that nearly 11 percent of the United States population had influenza. Yet the Centers for Disease Control and Prevention put the coughing and sniffling peak at 6 percent of the population. It turns out Google didn’t anticipate how outside influences, like media coverage of the flu and the rise in discussions on social media, would affect its data and statistics.
In 2010, researchers at Indiana University-Bloomington performed a similar study and found that people’s emotions on Twitter could help predict the stock market.

Media Decoder Blog: Young People Frequent Libraries, Pew Study Finds
In a digital world where many younger readers feel increasingly comfortable downloading novels and textbooks onto their computers or e-readers, a majority of Americans from the ages of 16 through 29 still frequent libraries.
According to a study released Monday by the Pew Research Center, 60 percent of Americans surveyed in this age group said they still visited the library. They use libraries to conduct research, borrow print, audio and electronic books and, in some cases, read magazines and newspapers.
That finding would seem to clash with the popular notion that young readers have turned away from libraries and print books as the source of their reading material, said Kathryn Zickuhr, research analyst with the Pew Research Center’s Internet and American Life Project. “A lot of people think that young people aren’t reading, they aren’t using libraries,” Ms. Zickuhr said. “That they’re just turning to Google for everything.”
The Pew Center has been researching the use of the nation’s libraries for more than two years, with financing from the Bill and Melinda Gates Foundation. The latest study involved a telephone survey, conducted last November and December, of nearly 3,000 people 16 and older talking about their reading habits, and data from two telephone polls conducted in January. While young people clearly do not read newspapers as regularly as their parents and grandparents did, their consumption of magazines is more closely aligned. The study showed that 40 percent of surveyed Americans under 30 regularly read newspapers, compared with 62 percent of older Americans. Seventy-one percent of those under 30 who do read news regularly said they viewed all of their news through hand-held devices.
While 42 percent of Americans under 30 read magazines, 50 percent of older adults read magazines.
But in troubling news for tablet makers, the study also found that the subjects under 30 who read electronically were more likely to read books on a cellphone or a computer.
In fact, the study found that 41 percent of readers under 30 view books using a cellphone and 55 percent read from a computer. Only 23 percent of Americans under 30 used an e-reader and 16 percent used a tablet.
“That’s definitely something we will keep an eye on,” Ms. Zickuhr said.
Assassin's Creed Movie Finds Studio
The Assassin’s Creed film moved a step closer to becoming a reality today, with Ubisoft teaming up with film studio New Regency to make the forthcoming video game adaptation, which is set to star Michael Fassbender.
According to Deadline, New Regency will finance and distribute the movie, while the Ubisoft Motion Picture division “will have strong creative input as the project moves into the script stage.”
“This is the perfect intersection of what we have been trying to do, and that is to work with top quality talent like Michael Fassbender,” explained Regency CEO Brad Weston. “We see this as our first big commercial action franchise property. Fassbender just did 12 Years A Slave with us, and he is as good an actor as there is right now. The storyline we are pursuing has a great narrative and because Ubisoft’s games are so character and story driven, Assassin’s Creed lends itself perfectly to our goal to re-brand Regency as a filmmaker driven company.”
“Ubisoft chose to partner with New Regency because they are a talent- and filmmaker-driven company, with the same independent and creative mindset that we have at Ubisoft Motion Pictures,” UMP CEO Jean-Julien Baronnet added. “Bringing aboard New Regency’s renowned production and distribution expertise while maintaining our own creative and financial flexibility ensures that Assassin’s Creed will be a high-quality film that respects the lore and fans of the video game franchise.”
And according to Variety, in addition to preserving elements of the game that make up its DNA – like the design of its characters and historical elements – Ubisoft hopes to tie the release of a film in with a new game launch.
Chris Tilly is the Entertainment Editor for IGN in the UK and is hoping that this will be the video game adaptation that doesn't suck. He can be found on both Twitter and MyIGN.

Bits Blog: On Big Real Estate Sites, Study Finds Gaps in Listings
For some time, executives at Redfin, an online real estate brokerage firm, grumbled to themselves that better-known real estate sites like Zillow and Trulia didn’t have all the property listings that Redfin and other sites had. So Glenn Kelman, the chief executive of Redfin, finally set out to prove it.
A study underwritten by Redfin to be released on Wednesday seeks to compare the comprehensiveness and accuracy of real estate listings on five sites, Zillow, Trulia, Redfin and the sites of two regional real estate brokerage firms, Windermere and Long & Foster. The study, conducted by a real estate consulting firm called the WAV Group, looked at a sample of 6,401 home listings in 33 ZIP codes from 11 metropolitan areas in the United States. It found that Redfin, Long & Foster and Windermere all had 100 percent of the agent-listed homes for sale, while Trulia had 81 percent and Zillow had 79 percent.
The study also found that 36 percent of the agent-listed properties shown as active listings on Zillow and and 37 percent of those on Trulia were no longer for sale on the local multiple listing service, or MLS, the local associations around the country through which agents share their property listings. The study said that 0.1 percent of the listings on Redfin and 1.7 percent of the listings on Windermere’s site were no longer for sale. All of Long & Foster’s listings mirrored their status in the local MLS.
O.B. Jacobi, the president of Windermere, a big real estate brokerage firm in the Pacific Northwest, said consumers should be aware that local real estate Web sites provide the most complete view of properties for sale. “If I’m doing the largest purchase of my life, I want to see everything,” Mr. Jacobi said.
Zillow and Trulia do not dispute that their listings have some gaps and inaccuracies, though they dispute some of the particulars of the Redfin study. There’s a simple reason they don’t have everything their rivals do: neither of them belongs to the local MLSes, which provide the most complete sets of agent-listed properties.
That’s because Zillow and Trulia are not real estate brokerage firms. Rather than making money by selling properties, the companies sell advertising and other services that allow agents to reach home shoppers and buyers through their sites. They have both built up big online audiences by packing their sites with a variety of information services, including real-time estimates of the value of properties.
Because Zillow and Trulia have such big audiences, they have been able to form relationships with many local real estate brokers like Windermere, which provide electronic feeds of all their listings. The problem with that approach, said Redfin’s Mr. Kelman, is that there are a lot of small real estate firms because the barriers are relatively low for entering the real estate businesses.
“Most of those mom-and-pop brokers don’t upload their listings” to sites like Zillow and Trulia, Mr. Kelman said.
Sometimes agents that do provide feeds to the sites don’t take listings down quickly when the properties sell, Mr. Kelman said. Although Redfin is an Internet start-up firm, it employs brokers, so it gets access to MLS listings.
Ken Shuman, a spokesman for Trulia, said the company had a dedicated team that was forming stronger relationships with brokers around the country to improve the completeness and accuracy of its real estate data. Mr. Shuman estimated that Trulia had about 90 percent of the property listings in the United States at any given time.
Cynthia Nowak, a spokeswoman for Zillow, said it was making a similar effort. “We’re always looking to improve accuracy,” she said.
“There is no gold standard for listings data, so comparing Zillow’s MLS-only listings to an MLS isn’t going to give you the whole picture. For example, Zillow has hundreds of thousands of rental, for-sale-by-owner, new construction and foreclosure listings, which often aren’t listed on an MLS,” she said.
“In addition to these listings, home shoppers visit Zillow for deep information on all homes, Zestimates, price cuts and community and historical home data, all of which typically can’t be found on a brokerage site,” she said
This post has been revised to reflect the following correction:
Correction: October 3, 2012
An earlier version of this article misstated the number of listings on Redfin that the site said were active but that a study said were no longer for sale. That number was 0.1 percent, not 0.1 percentage point.

Bits Blog: Microsoft Finds PCs That Ship Pre-Infected
One more thing to worry about: Your brand-spanking-new computer could be infected with a virus that will raid your online bank account.
On Thursday, Microsoft said it had discovered several new computers, fresh from Chinese factory floors, that carried a particularly pernicious computer virus — one capable of invading bank accounts, starting computer attacks and creating back doors that allow criminals to have their way with infected machines.
Microsoft’s digital crime researchers purchased 20 new computers from different cities in China and discovered that four of them had been infected with viruses. In each case, the computers were running counterfeit versions of Windows software that were infected with the virus.
That virus, called Nitol, reported back to a command and control center hosted by the Web domain 3322.org, which is registered to Bei Te Kang Mu Software Technology. That domain, Microsoft’s researchers say, hosts 500 different strains of malware. Some are capable of switching on a victim’s microphone or Web camera. Others record victims’ keystrokes, giving cybercriminals access to their log-in credentials and online bank accounts.
Microsoft got permission from a United States court to take down the network of Nitol-infected computers. The takedown was part of a civil suit brought by Microsoft in its increasingly aggressive campaign — called Project MARS, for Microsoft Active Response for Security — to take the lead in combating digital crime, rather than waiting for law enforcement to act.
Using similar legal means, Microsoft took down four other botnets — or networks of infected computers — in the last few years. In each case, Microsoft obtained a court order that allowed it to seize Web domains and computers associated with the botnets without first notifying the owners of the property. The court gave Microsoft permission to seize the 3322.org domain on Monday.
“This action will significantly reduce the impact of the menacing and disturbing threats associated with Nitol and the 3322.org domain, and will help rescue people’s computers from the control of this malware,” Richard Boscovich, a senior lawyer in Microsoft’s digital crimes unit, said in a blog post.
Peng Yong, the owner of Bei Te Kang Mu Software Technology, told The Associated Press that he was not aware of his domain’s seizure by Microsoft and that his company had a “zero tolerance” policy toward illegal activity on the domain. But he added that with 2.85 million domain names, his company “cannot exclude that individual users might be using domain names for malicious purposes.”
