NAF Sam Wainwright : Revolutionary communication innovations

By Sam Wainwright – Special to CNN   June 10, 2011

Editor's Note: Sam Wainwright is a Research Associate at the New America Foundation. This post is part of the Global Innovation Showcase created by the New America Foundation and the Global Public Square

New communications tools and behaviors are spurring innovation worldwide, revolutionizing finance, community, business, giving and government.  Here are some fascinating examples:

Finance: Mobile phone technology is empowering individuals to directly exchange money through their cell phones, bypassing traditional banking institutions. Companies like Square and their headphone-jack card reader let anyone with a smart phone accept credit card payments.

Mobile banking has developed even faster and spread far wider around the world. In Kenya, M-PESA connects over 65% of households to mobile money services. Websites like Kiva.org turn individuals into micro-financiers, allowing them to make $25 loans to anyone in the world.

Community: P2P technology is also facilitating near-free global communication through technology like Voice over IP (VoIP), turning even niche marketplaces into global exchanges.
Start-ups like Speak Shop, a web-based marketplace of Latin America Spanish tutors, allow  anyone, anywhere to brush up on their Español via Skype.

Alternative “mesh” Internet architectures are also emerging as challengers to traditional notions of centralized, institutional control over the web. When the Egyptian government attempted to shut down the country’s Internet last February, Egyptian hackers turned to mesh networking to bypass the blackout.

Business: People aren’t the only ones connecting in new ways. There are new direct company-to-person interactions, whether as simple as announcing deals on Twitter, or as complex as a Spiroxil’s system for detecting counterfeit prescription drugs in the developing world with a cellphone camera.

Companies are connecting with new workforces by crowdsourcing small tasks with Amazon’s Mechanical Turk, or by partnering with not-for-profits like Samasource to build sustainable internet-based jobs for people in poverty.

Giving: Charities have also benefited. Direct giving through text messages became a major source of international philanthropy – especially disaster relief – following the Haitian earthquake last year. Meanwhile, sites like GlobalGiving connect individual donors to grassroots charity projects with unprecedented levels of transparency and accountability.

A free service called ChildCount+ uses text messaging to coordinate community-based health providers in Africa. Beside providing for the social good of improving the delivery of health care, ChildCount+ means more patients end up coming back for follow-up appointments.

Government: Lower barriers to communication are also allowing individuals to hold governments accountable in ways never before possible. Ushahidi maps have been revolutionary in increasing government transparency. The free and open-source software allows anyone to report location-tagged information, and has been tweaked to track everything from street violence in Kenya to infrastructure damage from the Haitian earthquake. Residents of D.C. even used it to track snow removal during 2010’s “snowmaggedon.”

Perhaps most strikingly, many of these new interactions begin with the ethos of “free” and seek out new ways to monetize innovation outside of traditional cash-for-goods-rendered transactions. For example, Ushahidi software generates revenue by offering set-up and hosting services.

As Chris Anderson noted in his book Free: The Future of a Radical Price, “free” is “a word with an extraordinary ability to reset consumer psychology, create new markets, break old ones and make almost any product more attractive."

Taken together, all these breakthroughs suggest that the truly innovative work in the global economy is increasingly divorced from traditional models of individual ownership and old boundaries of communication. Indeed, new forms of communication are leading the way.

BIG Data and Economist Conference

Ideas Economy: Information is a fresh look at knowledge management for the information age.


Date:  7 June 2011 - 11:00am - 8 June 2011 - 6:00pm
Location:  Santa Clara Convention Center
5001 Great America Parkway
Santa Clara 95054

Watch Live Webcast at fora.tv


The era of big data presents incredible opportunities—smarter cities, stronger companies, faster medicine—but just as many challenges. Storage is scarce, systems overloaded, governments and businesses know too much. The world now contains unimaginably vast amounts of digital information, which is growing exponentially. Managed well, this data can be used to engineer new engines of economic value, unlock scientific breakthroughs, and hold politicians accountable. Managed poorly, it can cause great harm. The financial crisis showed that complex models that analyse large quantities of data do not always reflect financial risk in the real world. The financial crisis was sparked by big data—and there will be others.

But the data deluge will also generate millions of new ideas for how to solve big problems, build new markets, and expand existing ones. Ideas Economy: Information is a fresh look at knowledge management for the information age.

The Economist will bring together theorists, strategists, and innovators who understand how to harness data to create value and advance individual, corporate, and social good. We will sift through the vast quantities of current thinking on data to uncover the best ways forward. And we will apply the lessons of the Ideas Economy, about innovation, human capital, and intelligent infrastructure, to uncover new sources of growth and accelerate human progress across the globe.

UK: Connect: Patients and the Power of Data

May 30, 2011

Source: Young Foundation (UK)

Information is the lifeblood of high quality healthcare. There have been huge technological advances about how it can be used and by whom, which have been under utilised by the NHS. It is now possible to give people control over their own data. If this were done, it would have the potential to revolutionise healthcare delivery for patients, their families and carers.

This discussion paper sets out seven practical ways and examples, each of which the Young Foundation believes would transform health care delivery. These could improve patient experiences, reduced errors and omissions, improve communication and make healthcare more efficient and effective.

What Big Data Needs: A Code of Ethical Practices

Thursday, May 26, 2011

Four key principles that companies should follow if they hope to analyze customers' data without alienating them.

By Jeffrey F. Rayport

http://www.technologyreview.com/printer_friendly_article.aspx?id=37548

In this era of Big Data, there is little that cannot be tracked in our online lives—or even in our offline lives. Consider one new Silicon Valley venture, called Color: it aims to make use of GPS devices in mobile phones, combined with built-in gyroscopes and accelerometers, to parse streams of photos that users take and thus pinpoint their locations. By watching as these users share photos and analyzing aspects of the pictures, as well as ambient sounds picked up by the microphone in each handset, Color aims to show not only where they are, but also whom they are with. While this kind of service might prove attractive to customers interested in tapping into mobile social networks, it also could creep out even ardent technophiles.

Color illustrates a stark reality: companies are steadily gaining new ways to capture information about us. They now have the technology to make sense of massive amounts of unstructured data, using natural language processing, machine learning, and software architectures such as Hadoop, which handles high volumes of simultaneous search queries. Messy data of this kind, long relegated to data warehouses, is now the target of data mining. So is the information generated by social networks—user profiles and posts. Its quantity is staggering: a recent report from the market intelligence firm IDC estimates that in 2009 stored information totaled 0.8 zetabytes, the equivalent of 800 billion gigabytes. IDC predicts that by 2020, 35 zetabytes of information will be stored globally. Much of that will be customer information. As the store of data grows, the analytics available to draw inferences from it will only become more sophisticated.

It's no wonder that there are calls for corporations to create positions such as chief privacy officer, chief safety officer, and chief data officer, or that American and European legislators have been considering several kinds of privacy measures. In one bipartisan effort, Senators John McCain and John Kerry have proposed the Consumer Privacy Bill of Rights Act of 2011, which aims, in part, to restrict what online companies can do with customer data. Senator Jay Rockefeller has proposed his own piece of legislation, the Do-Not-Track Online Act of 2011. The European Union's Article 29 Working Group is addressing similar concerns.

In the private sector, the Digital Advertising Alliance has sought to get ahead of such rule-making by introducing its own privacy framework to assure the security and safety of customer information. Its Self-Regulatory Program for Online Behavior Advertising comes on the heels of several incidents: Epsilon's admission that hackers gained access to customer information from clients such as CitiGroup, Target, and Walgreen's; Sony's revelation that its PlayStation platform failed to safeguard the account information of up to 100 million customers; and Apple's  confirmation that it uses an unencrypted file stored in iTunes accounts to track movements of individual iPhone users in the physical world.

For all the privacy concerns, the online economy creates enormous value by using customer information. In 2009, according an ad industry study cited by the Wall Street Journal, the average price of an untargeted ad online was $1.98 per thousand views. The average price of a targeted ad was $4.12 per thousand. We used to measure the success of websites as if they were portals—by how much traffic they could muster. Now we measure them as social networks—by how much they know about their users. This is why Wal-Mart recently acquired Kosmix, a Silicon Valley startup that filters and finds meaning in vast streams of Twitter messages. Other retailers, along with digital players such as Facebook and Yahoo, are using the technology of another startup, Cloudera, to sort through enormous quantities of behavioral information compiled over years (sometimes decades) in search of insights based on patterns that only machines can fathom. Intelligence generated in these ways can lead to better games from companies like Zynga and better advertising from your favorite brands. David Moore, the CEO of 24/7 Real Media, argues that when an ad is targeted properly, "it ceases to be an ad; it becomes important information."

The opportunity for profit helps explain the rise of dozens of data exchanges, data marts, predictive analytic engines, and other intermediaries. It's also why players such as Google, Facebook, and Zynga, among many others, are finding ways to aggregate ever more information about users. Facebook provides but one example of how extensive this kind of tracking can be. Its seemingly innocuous "Like" button has become ubiquitous online. Click on one of these buttons, and you can instantly share something that pleases you with your friends. But simply visit a page with a "Like" button on it while you're logged in to Facebook, and Facebook can track what you do there. The first aspect sounds great for consenting adults; the latter is more than a little unsettling. Facebook is hardly alone. A company called Lotame helps target online advertising by placing  tags (sometimes known as beacons) on browsers to monitor what users are typing on any Web page they might view.

The potential dark side of Big Data suggests the need for a code of ethical principles. Here are some proposals for how to structure them.

Clarity on Practices: When data is being collected, let users know about it—in real time. Such disclosure would address the issue of hidden files and unauthorized tracking. Giving users access to what a company knows about them could go a long way toward building trust. Google has done this already. If you want to know what Google knows about you, go to www.google.com/ads/preferences, and you can see both the data it has collected and the inferences it, and third parties, have drawn from what you've done.

Simplicity of Settings: One way to avoid an Orwellian nightmare is to give users a chance to figure out for themselves what level of privacy they really want. In theory, Facebook does this. In practice, as Nick Bilton reported recently in the New York Times, Facebook's privacy policy has more words (5,830) than the United States Constitution (4,543, not counting the amendments). But that's just the tip of the iceberg. Try changing your privacy settings, and you will encounter over 50 privacy toggles giving rise to over 170 privacy options.

Privacy by Design: Some argue that neither clarity nor simplicity is sufficient. Ann Cavoukian, privacy commissioner for the province of Ontario, coined the phrase "privacy by design" to propose that organizations incorporate privacy protections into everything they do. This does not mean Web and mobile businesses collect no customer information. It simply means they make customer privacy a guiding principle, right from the start. Microsoft, which in 2006 issued a report called "Privacy Guidelines for Developing Software Products and Services," has embraced this principle, using a renewed emphasis on privacy as a way to differentiate itself; the latest version of Internet Explorer, IE9, lets users activate features that can block third-party ads and content.

Exchange of Value: Walk into a local Starbucks, and you're likely to feel flattered if a barista remembers your name and favorite beverage. Something similar applies on the Web: the more a service provider knows about you, the greater the chance that you'll like the service. Radical transparency could make it easier for digital businesses to show customers what they will get in exchange for sharing their personal information. That's what Netflix did in running a public competition offering third-party developers a $1 million award for creating the most effective movie recommendation engine. It was an open acknowledgement that Netflix was using users' movie-viewing histories to provide increasingly targeted, and thus more useful, recommendations.

These principles are by no means exhaustive, but they begin to outline how companies might realize the value of Big Data and mitigate its risks. Adopting such principles would also get ahead of policymakers' well-intentioned but often misguided efforts to rule the digital economy. That said, perhaps the most important rule is one that goes without saying, something akin to the Golden Rule: "Do unto the data of others as you would have them do unto yours." That kind of thinking might go a long way toward creating the kind of digital world we want-and deserve.

Surowiecki/New Yorker on economic data


A Billion Prices Now

By James Surowiecki May 30, 2011 The Financial Page

Between official government statistics, industry surveys, and Wall Street forecasts, it often seems like we're drowning in data, often of uncertain value. But consider the alternative. In the early years of the Great Depression, it was clear that things were awful, but the government had few good figures to go on; there was no official G.D.P. number, and no solid information about unemployment. As a result, policymakers persistently underestimated the severity of the crisis. In June of 1930, relying on some anecdotal evidence of an upturn, Herbert Hoover announced, "The Depression is over."

And in his State of the Union address that December he said that two and a half million Americans were unemployed. But, as Hoover acknowledged, that number was eight months old. At the time of the speech, five million people were out of work, and a hundred thousand more were losing their jobs every week. Washington was making policy in the dark.

The government learned from experience, though. In 1934, a team of economists came up with the first measurement of national income, which developed into what we now know as G.D.P. The late thirties saw a more rigorous and systematic collection of unemployment data. And in the years after the Second World War—which accelerated the trend toward quantifying things—the amount of economic information available to policymakers grew exponentially. Today, our picture of the economy is more detailed and sophisticated than ever, and that makes it easier for businesses and the government to react quickly to changes in the economy.

And yet our picture of what's going on is far from perfect. The government continues to track inflation, for instance, by gathering price data much as it did in the nineteen-fifties: it surveys consumers by phone to see where they buy, surveys businesses to see how much they charge, checks out shopping malls to price goods. This leaves out consumers who have only cell phones, and it probably overstates inflation by not fully accounting for things like the impact of big-box stores. The larger problem, though, is the time it takes: the Consumer Price Index's figures don't come out until a month after the fact. In turbulent times, that's too slow.

A new venture called the Billion Prices Project may help change that. The B.P.P., which was designed by the M.I.T. economists Alberto Cavallo and Roberto Rigobon, gathers price data not via survey but, rather, by continuously scouring the Web for prices of online goods around the world. (In the U.S., it collects more than half a million prices daily—five times the number that the government looks at.) Using this information, Cavallo and Rigobon have succeeded in building what amounts to the first real-time inflation index. The B.P.P. tells us what's happening now, not what was happening a month ago. For instance, after Lehman Brothers went under, in September, 2008, the project's data showed that businesses started cutting prices almost immediately, which suggested that demand had collapsed. The government's numbers, by contrast, didn't show this deflationary pressure until that November. This year, there's been a mild uptick in annual inflation, and again the B.P.P. detected the new trend before the Consumer Price Index did. That kind of early heads-up could help governments make more timely decisions.

The B.P.P. can also help keep governments honest. In much of the world, as a 2010 study of developing countries found, governments regularly manipulate economic data—downplaying inflation, overstating job growth, and the like. The B.P.P. makes that more difficult by providing an independent check on the official numbers. And, while there's no evidence that this kind of thing happens in the U.S., if you're a conspiracy theorist you can now look to the B.P.P. rather than to the regular inflation number to see what's happening.

The B.P.P. doesn't offer a complete picture. In particular, it doesn't cover most services. But, even if it's unlikely to replace the C.P.I. anytime soon, it will almost certainly make the C.P.I. better. Indeed, it wouldn't be surprising if the Bureau of Labor Statistics, which has already said that some of its methods are out of date, begins to move toward a real-time model. The B.P.P., in its rough-and-ready way, is part of a data revolution. Cheap computing power and the Internet have made it possible for companies to do what previously only the government could. The Case-Shiller Index of home resale prices, for instance, has become the benchmark for U.S. house prices. The most concrete result of all this is that policymakers will be better informed than ever before. It also means that they'll have fewer excuses when they mess up.

That's the catch, of course. Giving policymakers more information doesn't mean that they'll believe it or act on it. In the years leading up to the financial crisis of 2008, after all, there was a lot that people didn't know, but the fundamental problems were obvious: housing prices were rising too fast and banks were flinging loans at unqualified borrowers with reckless abandon. Yet the Federal Reserve and banking regulators failed to take any action to try to pierce the bubble before it brought the economy crashing down. These days, all the available numbers, including the C.P.I. and the Billion Prices Project, suggest that inflation is under control. Still, politicians and some Fed members are fretting that a huge price spike may be imminent, and are pushing to make monetary policy tighter, even in the face of unacceptably high unemployment. An enormous amount has been done lately to make sure that policymakers have the numbers they need. The question is whether they'll use them. ♦



'Jeopardy!'-winning computer delving into medicine

YORKTOWN, N.Y. (AP) — Some guy in his pajamas, home sick with bronchitis and complaining online about it, could soon be contributing to a digital collection of medical information designed to help speed diagnoses and treatments.

A doctor who is helping to prepare IBM's Watson computer system for work as a medical tool says such blog entries may be included in Watson's database.

Watson is best known for handily defeating the world's best "Jeopardy!" players on TV earlier this year. IBM says Watson, with its ability to understand plain language, can digest questions about a person's symptoms and medical history and quickly suggest diagnoses and treatments.

The company is still perhaps two years from marketing a medical Watson, and it says no prices have been established. But it envisions several uses, including a doctor simply speaking into a handheld device to get answers at a patient's bedside.

Watson won't be the first such product on the medical market, however, and one rival company says it isn't impressed.

At a recent demonstration for The Associated Press, Watson was gradually given information about a fictional patient with an eye problem. As more clues were unveiled — blurred vision, family history of arthritis, Connecticut residence — Watson's suggested diagnoses evolved from uveitis to Behcet's disease to Lyme disease. It gave the final diagnosis a 73 percent confidence rating.

"You do get eye problems in Lyme disease but it's not common," Dr. Herbert Chase said. "You can't fool Watson."

For "Jeopardy!" Watson was fed encyclopedias, dictionaries, books, news, and movie scripts. For health care, it's on a diet of medical textbooks and journals. It could also link to the electronic health records that the federal government wants hospitals to maintain. Medical students are peppering it with sample questions to help train it.

Chase, a Columbia University medical school professor, says anecdotal information — such as personal blogs from medical websites — may also be included.

"What people say about their treatment ... it's not to be ignored just because it's anecdotal," Chase said. "We certainly listen when our patients talk to us, and that's anecdotal." Chase and other experts say cramming Watson with the latest medical information will help with a major problem in modern health care: information overload.

"For at least 30 years it's been clear that it's not possible for us to know everything," he said. "Every day, doctors have questions they can't find the answers to. Even if you sit down at a search engine, it's so labor intensive and it takes so long to find answers."

Carl Kesselman, director of the Health Informatics Center at the University of Southern California, says the "deluge of information" is a significant problem.

"Advances in medicine are increasing rapidly: genomics, specialized drugs, off-label uses, increasingly finer-grained classifications of disease," said Kesselman, who is not involved with the Watson project. "The ability to ask 'Jeopardy!'-style questions and get that kind of information retrieval, to sort through all the stuff out there and point you to the latest literature, would be of potentially huge value."

Michael Yuan, chief scientist at Ringful Health, a medical consulting company in Austin, Texas, that has worked with IBM, cited a 1999 study of 103 doctors that found they fielded more than 1,100 questions a day, of which 64 percent were never answered.

"That's a huge potential for people to make mistakes," he said. "Watson is the type of solution that can really reduce that."

In "Jeopardy!" Watson was asked for one correct answer, whether it was answering questions about Sir Christopher Wren, the Lion of Nimrud or the Church Lady from "Saturday Night Live."
But in its medical guise, when presented a set of symptoms, Watson offers several possible diagnoses, ranked in order of its confidence.

"In medicine, we don't want one answer, we want a list of options," Chase said.
Kesselman said having options might help doctors accept a computer's findings.
"Will a physician ever blindly accept a diagnosis coming out of a computer? I don't think that will happen anytime soon," he said.

Chase said seeing more than one choice might also help doctors move away from what he called "anchoring," or getting too attached to a diagnosis.

"If a person has a 95 percent chance of having disease X, there's still a one-in-20 chance that they have something else," he said. "We often forget what's in that 5 percent. But Watson won't."

The treatment application works much like the diagnosis application. In the demonstration, Watson first suggested the antibiotic doxycycline for treating Lyme disease, then switched to cefuroxime when told the patient was pregnant and allergic to penicillin.

Chase said Watson will know the latest treatment guidelines — which are complex and often updated — "and can see if they're not being met."

"You have to match the right treatment with each unique patient," Chase said. "You can't treat everybody with high blood pressure the same way — a 75-year-old man with prostate cancer who felt dizzy last week and a 32-year-old woman."

Yuan said Watson's influence will depend on "how widely it is adopted."

"You have to wonder if a hospital is going to plunk down a couple of million dollars," he said.
IBM's Dan Pelino, general manager for global health care, said clients won't have to buy a complete Watson system. He said possible future uses include:

·       Allowing a doctor to connect to Watson's database by speaking into a hand-held device, using speech-recognition technology and cloud computing;
·       Serving as a repository for the most advanced research in cancer or other fields;
·       Providing an always-available second opinion.
·       "You can imagine someone asking Watson a question on an iPad as they're walking down the hall," Chase said. "It might get updates like a GPS."

An existing private medical database known as Isabel is already used by some multi-hospital health systems. Co-founder Jason Maude of Isabel Healthcare said that from what he's heard about IBM's plans for Watson, "It's kind of what we've had for about 10 years."

An online demonstration of Isabel showed similarities to the Watson model — symptoms are entered, and the computer searches through a database for a possible diagnosis. Maude, who named Isabel for a daughter who escaped a serious misdiagnosis as a child, says Isabel's database has been "tuned and honed" over time.
He said prices for using Isabel range from a few thousand dollars a year for a family practice to as much as $400,000 for a health system.

Pelino said Watson is much faster and Chase said Watson is better at understanding non-medical terms.

"Watson knows that 'difficulty swallowing' is 'dysphagia,'" he said.

Isabel has been used at the Orlando Health hospital network in Florida since last fall, and "has had its successes," said Dr. Jay Falk, chief academic medical officer. He said less experienced doctors use it under the guidance of senior clinicians "who can make some judgments about the likelihood of what's given on the list of diagnoses."

"There's no question that there's a need for a tool that will help in this regard," Falk said. "Whether Isabel itself is the answer is unclear." Overall, he said, "We're enjoying learning with it."

IBM said Watson can answer some medical questions in the same few moments it took on "Jeopardy!" Yuan noted studies have shown that "If it takes more than two minutes, it won't get used."

As on "Jeopardy!" — where Watson identified Toronto as a U.S. city and Picasso as an art period — the computer occasionally bungles a medical question.
"I think once we were asking what type of drug we should use and the answer was a person's name," Chase said. "In fairness, I think it was a person associated with the drug."

And of course there are things Watson cannot do. It won't know a patient's appetite for risk, for example, or feelings about end-of-life treatment.

"That's why you have to emphasize that the decisions aren't coming from the computer, they're coming from the patient," Chase said.

Chase's suggestion that medical blogs be included may have something to do with his own medical history.

Several years ago, fighting a cholesterol problem, he took Lipitor and was soon plagued with insomnia. He suspected a connection but found nothing in textbooks or journals.
"I go to the blogosphere, and it was like, 'You moron, don't take Lipitor before you go to bed because you'll never sleep again!'

"Now it's five years later, and if you Google Lipitor and insomnia, it's all over the place," Chase said.

New Ways to Exploit Raw Data May Bring Surge of Innovation, a Study Says

By Steve Lohr NY TImes, May 13, 2011

Math majors, rejoice. Businesses are going to need tens of thousands of you in the coming years as companies grapple with a growing mountain of data.

Data is a vital raw material of the information economy, much as coal and iron ore were in the Industrial Revolution. But the business world is just beginning to learn how to process it all.

The current data surge is coming from sophisticated computer tracking of shipments, sales, suppliers and customers, as well as e-mail, Web traffic and social network comments. The quantity of business data doubles every 1.2 years, by one estimate.

Mining and analyzing these big new data sets can open the door to a new wave of innovation, accelerating productivity and economic growth. Some economists, academics and business executives see an opportunity to move beyond the payoff of the first stage of the Internet, which combined computing and low-cost communications to automate all kinds of commercial transactions.

The next stage, they say, will exploit Internet-scale data sets to discover new businesses and predict consumer behavior and market shifts.

Others are skeptical of the “big data” thesis. They see limited potential beyond a few marquee examples, like Google in Internet search and online advertising.

The McKinsey Global Institute, the research arm of the consulting firm, is coming down on the side of the optimists in a lengthy study to be published on Friday. The report, based on nine months of work is “Big Data: The Next Frontier for Innovation, Competition and Productivity.” It makes estimates of the potential benefits from deploying data-harvesting technologies and skills.

The McKinsey research unit, for example, says the value to the health care system in the United States could be $300 billion a year, and that American retailers could increase their operating profit margins by 60 percent.

But the study also identifies challenges. One hurdle is a talent and skills gap. The United States alone, McKinsey projects, will need 140,000 to 190,000 more people with “deep analytical” skills, typically experts in statistical methods and data-analysis technologies.

McKinsey says the nation will also need 1.5 million more data-literate managers, whether retrained or hired. The report points to the need for a sweeping change in business to adapt a new way of managing and making decisions that relies more on data analysis. Managers, according to the McKinsey researchers, must grasp the principles of data analytics and be able to ask the right questions.

“Every manager will really have to understand something about statistics and experimental design going forward,” said Michael Chui, a senior fellow at the McKinsey Global Institute.

The study estimates that the use of personal location data could save consumers worldwide more than $600 billion annually by 2020. Computers determine users’ whereabouts by tracking their mobile devices, like cellphones. The study cites smartphone location services including Foursquare and Loopt, for locating friends, and ones for finding nearby stores and restaurants.

But the biggest single consumer benefit, the study says, is going to come from time and fuel savings from location-based services — tapping into real-time traffic and weather data — that help drivers avoid congestion and suggest alternative routes. The location tracking, McKinsey says, will work either from drivers’ mobile phones or GPS systems in cars.

Personal location data raises privacy concerns. Both Google and Apple, for example, have faced protests recently for collecting location data without most users’ knowledge. The McKinsey report says such services should require that users have a choice and opt-in to use them, but the report does not deal with privacy issues in detail.

The sizable projected payoff for consumers, some experts say, is not surprising. “Much of the benefit of innovation always flows to consumers,” said Martin Baily, an economist at the Brookings Institution, who was an adviser on the study. “So the large consumer surplus makes sense.”

In health care, the biggest slice of the $300 billion gain is expected to come from more effectively using data to inform treatment decisions. The tools include clinical decision support to assist doctors, and comparative effectiveness research to make more informed decisions on drug therapy.

For example, the Department of Veterans Affairs and Kaiser Permanente save millions of dollars a year in treating many patients with high cholesterol with generic statins instead of branded statins, like Lipitor. But such tailored treatments require electronic health records for tracking results, and most of the nation’s hospitals and physicians still use paper records.

Skeptics say the economic payoff from harnessing big data sets is mostly wishful thinking so far. The nation’s technology-assisted increase in productivity began in 1995 and continued through 2004, having trailed off since, despite investments in data analytics.

“The big dividend mostly hasn’t arrived yet,” said Tyler Cowen, an economist at George Mason University.

The McKinsey authors say that the big-data trend is just getting under way. It will take years, they say, before the gains show up in the economic statistics, just as it did for computers to prove they were engines of productivity.

“But it’s clear that data is an important factor of production now,” said James Manyika, a director of the McKinsey Global Institute.

4 Trends Shaping the Emerging "Superfluid" Economy

This post originally appeared on CNN.com’s Global Public Square.

Humanity and technology continue to co-evolve at an ever increasing pace,  leaving traditional institutions (and mindsets) calcified and out of date. A new paradigm is emerging, where everything is increasingly connected and the nature of collaboration, business and work are all being reshaped. In turn, our ideas about society, culture, geographic boundaries and governance are being forced to adapt to a new reality.

While some fear the loss of control associated with these shifts, others are exhilarated by the new forms of connectivity and commerce that they imply. Transactions and interactions are growing faster and more frictionless, giving birth to what I call a “superfluid” economy.  
   
Business will not return to usual. So let’s discuss 4 key concepts to help us  better understand the shifts that are underway:

1. Quantifying and mapping everything

Technological acceleration isn’t just a phrase. Whether looked at through the lens of the Law of Accelerating Returns or the trend described as Moore’s Law, computing capabilities continue to increase exponentially. Our devices are becoming smaller yet more powerful. Cost continues to drop.

This may lead to technologies becoming so tiny that they simply fade into the background experience of our lives.

So what? What is the purpose of faster, more powerful technology? What are we trying to accomplish?

Think about it this way:  The whole of human history has been spent trying to understand ourselves, our environment and what it all means. Whereas a guru might advise “Know thyself,” a technologist might suggest “Quantify thyself.”

Technology tackles the challenge of self knowledge through the pursuit of full-systems quantification - creating a simulation and map of everything.

This is already happening all around us at the individual level.  Our location is being tracked by our mobile devices.  Our preferences, buying behaviors and social connections are being tracked online.  Our providers and 3rd party agencies are tracking our financial histories and medical records.

The aggregated information forms a digital profile of who we are and what we care about. This information can be helpful in creating personalized recommendations for products and services. It also makes governmental surveillance or manipulation that much easier. On the other hand, making previously invisible information transparent means it can be quantified and measured, so economic value can be tied to it.

On a larger scale, we’re seeing how data can be converted to become a useful tool for crisis mapping and visualizing real-time information. Supply chains can be mapped to help us assess the carbon footprint of the products we purchase. There’s even an initiative to map the real-time statistics of the entire planet, dubbed the Earth Dashboard.

The big picture is that the more information we’re able see, the more effective we can be at making intelligent decisions that have positive effects on our lives and our environment.

2. Everyone has access to the internet

One of the effects of cheaper, web-enabled devices is that we’re moving towards getting the world online. Half a billion people worldwide accessed the mobile internet in 2009, and that number is estimated to double over the next 5 years. A recent forecast by In-Stat projects close to a billion smart phones will be shipped worldwide by 2015.

In countries and emerging markets with low or no connectivity, the financial and infrastructural challenges of laying down cables will be leapfrogged as these places transition directly to a wireless web via mobile devices.

In addition, the ‘unbanked’ are being brought into financial inclusion through innovative services like M-PESA that enable the transfer of money via mobile phones. So within a few short years, we may see billions more people connected to the internet and capable of participating in economic transactions.

For those that are already connected, the move to mobile is making the distinction between being online and offline disappear. It’s estimated that about 788 million people will access the Web solely through their mobile device by 2015, meaning the web will simply go with us wherever we go.

Add in mobile augmented reality (Layar, Wikitude, Acrossair), which provides an information layer onto our immediate environment, along with near-field communication technologies, which enable contextual information to be sent to you based on your location, and we have an extremely empowering tool literally at our fingertips at all times.

3. Self-organizing expands

How we feel about things, how we organize collective action and how we exchange value with others are central themes to social, political and economic life. Each of these areas is now being expressed online in more robust and granular ways.

Comments, Facebook likes, recommendations, and reviews all contribute to the growing layer of social metrics that reveal general perception around brands, people, events, issues and topics of interest. Not only could this alter the way democracy works by gathering real-time sentiment and developing positive feedback loops for improving civil society, it also shifts the way people make decisions about purchases or lifestyle behaviors. Businesses are finding that customer engagement is becoming a more collaborative and co-creative experience – a partnership instead of just one-way communication and pushing a sale.

The ability to express sentiment and then self-organize around shared interests or common causes also has far-reaching implications for how the world operates.

As we’ve seen in the recent uprisings in the Middle East, networking tools can empower people to unite and organize collective action. In less disruptive scenarios, they enable businesses to form new partnerships, organizations to share resources or individuals to collaborate on a project at the neighborhood level.

4. Peer-to-peer exchange changes the future of money

All of these tools offering ways for people to connect, quantify, collaborate, and take action add up to new infrastructures for building trust and exchanging value at every level. You canexplore Collaborative Consumption to see the hundreds of peer-to-peer marketplaces that are springing up around the world, or check out The Mesh Directory to see how businesses are leveraging social networks and resource sharing to up their efficiency.

As money and exchange increasingly go digital, our assumptions about what “currency” means are also being challenged. Facebook Credits, for example, are Facebook’s internal virtual currency used to purchase digital goods within their game ecosystem. There are already apps being developed to reward potential customers with discounts and free merchandise in exchange for playing social games and brands are rewarding users with Credits to perform certain actions on their behalf.

On the fringes of society exists the complementary currency market – a range of mechanisms that allow for peer-to-peer value exchange through mutual credit systems like LETS or via decentralized currencies like Bitcoin. When the tools are in place to allow individuals or groups within a local area to easily exchange value without using traditional/centralized currency, it’s reasonable to expect a serious challenge to the ingrained public perception of money.

How to be “superfluid”

We live in a vast series of interconnected and nested systems, each affecting how the others operate. The shifts we’re seeing aren’t siloed or isolated, but rather systemic changes that have been happening throughout evolutionary history. They’re now happening at an accelerated rate, which means we have to adapt by finding ways to stay resilient and agile in a constantly changing environment.

Those finding success are adopting a “both/and” approach, rather than a black and white “either/or” solution. It is not necessary to abandon every time-tested practice and jump headfirst into something radically new. But, it is wise to integrate new approaches as a sort of hybrid “coopetition” – going from push to pull, defining a new capitalism, and welcoming “social” as a 21st century strategy.

The future we aspire to consists of business practices and ethics that are not zero-sum, meaning that cooperation and trust can lead to benefits for all. Unused or mis-allocated resources are channeled to unmet needs. Wealth is not just a number on a financial statement, but rather a celebration of sustainable and resilient communities, a clean environment and an educated and informed society.
It is our choice to enable such a future or not. In the end, we’re all in this together.

Facebook Could Be Planning a Visual Dashboard of Your Life

The data entered by millions of social-network users could be turned into revealing infographics.
By Christopher Mims

Ever wondered just how much coffee you drank last year, or which movies you saw, and when? New Web and mobile apps make it possible to track, and visualize, this personal information graphically, and the trend could be set to expand dramatically.

This is because Facebook recently acquired one of the leading personal-data-tracking mobile apps and hired its creators. The social-networking giant could be gearing up to offer users ways to chart the minutiae of their lives with personalized infographics.

Nick Felton and Ryan Case, two New York-based designers, have pioneered turning the mundane contours of an everyday life into a kind of visual narrative. Each year, Felton publishes an "annual report" on his own life: an infographic that charts out his habits and lifestyle in great detail.

Felton and Case have also created a mobile app, called Daytum, that lets users gather personal data and represent it using infographics. Daytum already has 80,000 users, whose pages provide a detailed snapshot of everything from coffee drinking habits to baseball stadium visits. The app gives users the ability to easily record their own information, whatever it might be, and display it in an attractive manner, whether or not they are a designer.

Daytum is part of a larger trend in tracking personal information. But traditional personal tracking applications tend to revolve around medical data, sleep schedules, and the like. In Felton's creative visualizations, even something as mundane as how many concerts he attended in the past year becomes a kind of art. "I think there's storytelling potential in data," he says.

Felton says he can't talk about what he'll be doing at Facebook, but says, "Clearly, companies like Facebook recognize the value of the kind of work we were doing."

At Facebook, users already engage in countless acts of data entry, so it's possible that the data Felton will be visualizing will already be available. Automated data gathering through smart phones—especially location data—provides even more data to mine.

Eventually—with users' permission—this kind of personal information could be mined by marketers and advertisers. Ted Morgan, CEO of the geolocation software company Skyhook, compares the trend to the way advertisers currently track some TV viewers' watching habits. In the future, he says, tracking data will be "like a Nielsen rating box for your life. It will track where you go and what you do. [Advertisers are] going to pay people to do this."

One company is already exploring this possibility. Locately offers users promotions and discounts if they agree to opt in to its mobile data-gathering network. This lets the company gather data on where people go, what they do, and what they buy; the company sells that data to businesses who want to use it for market research and advertising.

Gathering detailed personal data can produce surprising insights, says Felton. "The way people describe themselves is not really in line with their true behavior," he notes. For example, users who track what TV shows they actually watch may find that they spend more time on shows they don't identify as their favorites.

Perhaps this could lead to a whole new kind of friend discovery, one based not on our expressed interests, but on our actual interests. Picture a beefed-up version of Facebook's "people you might also know" feature informed not just by who you're connected to, but what behavior you have in common.

"It could be shared affinities that are not recognized by either [party]," says Felton. The downside, of course, is that people who are a lot like us often drive us crazy. "You might hate them," says Felton. "Isn't that part of what annoys us about our families?"

FT: A binary goldmine

Financial Times, May 5 2011

Displaying up-to-the-minute information on everything from train times to cinema schedules, apps have in short order become a ubiquitous feature of smartphones. To most users, they are simply useful and entertaining tools.

As well as providing users with information, however, these mobile software applications are also insatiable data-gatherers. Even the most mundane apps often collect a surprising amount from handsets just to do their jobs.

This has put them at the forefront of a fast-evolving science based on the business use of consumer data. If there is commercial advantage to be gained, it seems, almost nothing is too insignificant to be collected and analysed.

Take an app launched recently by Color, one of the most ambitious and best financed of the crop of start-ups that has sprung up in Silicon Valley to cash in on the smartphone boom. Pictures taken by users are mixed into streams with those taken by others who are nearby, or with whom users are often in contact, building ad hoc social networks.

The software taps deeply into handsets, drawing on components such as Global Positioning System chips, gyroscopes and accelerometers to pinpoint where they are, how fast they are moving and which way up they are being held. The lighting conditions in pictures taken with the gadgets, along with the digital “fingerprints” of surrounding noises coming through their microphones, provides other useful crumbs of information.

Thus informed, Color can work out precisely who the user is walking down the street with, says Bill Nguyen, the serial entrepreneur behind the company.

Such innovations are the tip of a data iceberg. Smartphones, social networks and other accoutrements of modern digital life are generating vast new data sets that are revving up the digital economy.

Accompanying all this is a trend that has given the technology lexicon a new term: big data. Rather than sampling only small parts of the digital data deluge, modern companies have a new option: they can study all of it.

The ability to capture and analyse this mass of information is throwing up business ideas and altering the relationship between businesses and their customers.

TECHNOLOGICAL TOOLS
Messy, lacks structure but holds promise: an interim report card on big data

The idea of amassing a large amount of data and scrutinising it for clues about customer behaviour is not new in business. Data mining has long been used by big companies with access to enough computing power, such as credit card issuers and retailers.

But the falling cost of technology and the generation of much more digital information have opened the field to a much wider group of businesses and made it possible to make more informed judgments about customer behaviour.

While “big data” has become the buzzword, a better description would be “messy data”, says Roger Ehrenberg of IA Ventures, an early-stage investor. Harvesting, cleaning up and organising raw data in a way that it can be processed is a large part of the battle, he says.

This has been complicated further by the big growth in unstructured data – information, such as text, that is not organised in a way that a computer can easily process. With the volume of user-generated text and video growing rapidly, this has become one of the main focuses of technological development.

Chief among the new tools are natural language processing, which enables a computer to extract meaning from text, and machine learning, the feedback loops through which computers can test their conclusions on large amounts of data in order progressively to refine their results.

Subjecting large data sets to analysis has also been made easier by two of the forces that have reshaped information technology more widely: the spread of low-cost, standardised computer hardware and the emergence of open-source software.

This has created a cheap computing platform for new technologies such as Hadoop – a piece of software architecture that is designed to handle massive amounts of data. The idea was based on breakthroughs at Google, which needed to find ways to conduct large volumes of intensive web searches simultaneously. It has since been taken up by companies including Facebook and Yahoo.

The rise of cloud computing – which centralises storage and processing power in larger data centres – has also brought big data within the reach of more companies. By tapping into the cloud computing services offered by Amazon, say, a company such as Color can get instant access to all the analytical power it needs without needing to take on the fixed costs of buying its own servers, says D.J. Patil, chief product officer at the IT start-up.

It is also stoking simmering privacy concerns. When Steve Jobs, Apple chief executive, was forced to apologise last week over the handling of data about the location of iPhone and iPad owners, it touched a raw public nerve and resulted in immediate Congressional hearings in Washington.

Color says it plans to use the information it collects to create new services for its customers. By combining it with data from social networks, says DJ Patil, chief product officer, it can tell its users: “Here are people who are near you, and here is how you might know them.” He says the company has no plans, at least for now, to use the information for other purposes, such as sending targeted advertising to customers.

However, with the tide of digital information rising fast – and more sophisticated ways being found to make business use of it – many companies are already being drawn into the new world of sophisticated data collection and analysis.

Some are using it to tailor their own products more precisely to the preferences of their users; others to target advertising of their products more accurately. Some are also selling the data they gather from their customers to the brokers and aggregators who act as middlemen in data markets that have sprung up to recycle such information.

A new consensus is needed to govern the use of this increasingly valuable commodity, says Michele Luzi of management consultancy Bain & Company, which conducted a study for the World Economic Forum on the issue. “Ultimately, you have to have a system of rights,” he says – something that balances the valid, but often conflicting, interests of individuals, governments and businesses.

While lawmakers and regulators on both sides of the Atlantic are becoming more exercised, such an agreement – not to mention the infrastructure and regulations to support it – remains some way off.
Meanwhile, as the analysis of digital information develops, the traditional management virtues of gut instinct and seat-of-the-pants decision-making are being replaced by reliance on intensive number-crunching and the objective testing of multiple potential courses of action.

For business leaders, “the big skill in future will be to ask the right question”, says Tim O’Reilly, a technology commentator and publisher.

Besides smartphones, new sources of data include social networks, blogs and other sources of user-generated content; sensors collecting everything from traffic patterns to a user’s heart rhythm; and click streams generated by people spending an increasing amount of their lives online.

Much of the information is in unstructured form. It has never been collated in a traditional relational database, where it could be queried at will. Without techniques to harvest, verify and analyse it – often in real time – valuable commercial signals are lost in the noise.

It sometimes takes the analysis of massive data sets to detect useful patterns, says Michael Olson. His California start-up, Cloudera, is commercialising the type of technology used by companies such as Facebook and Yahoo to crunch through vast bodies of information. Retailers, for instance, might learn far more from the 10 years’ worth of customer data they can now analyse in one go than from the more limited runs to which they were once restricted, he says.
. . .
Companies born in the digital age are often highly attuned to the possibilities presented by these untapped reservoirs of digital information. Like Color, they place data collection and analysis at their core, and build their business processes on their skills in these areas.

Even businesses whose roots appear to lie in the creative industries now treat data collection and analysis on a vast scale as a core skill. Zynga, which has produced online gaming hits such as FarmVille, believes that by analysing in painstaking detail what users do on its site it can perfect the experience. It mines these data, for instance, to model how users are likely to respond to new features. Zynga’s executives suggest this will ultimately leave it less exposed to the hit-and-miss nature of the games industry (a theory that has yet to be put to the test.)

“Their uniqueness is really in the massive pool of data that is growing every day,” says Theresia Gouw Ranzetta of Accel Partners, a venture capital firm that has backed a Zynga rival that uses similar techniques.

Data mining has long been central to fields such as credit-card marketing. The difference today is that it is becoming available to many more companies at lower cost. In addition, highly valuable new classes of information are emerging.

Social data, in particular, are at the centre of something of a gold rush. Gaining insight into the new rubric of online behaviour ushered in by sites such as Facebook and Twitter has the potential to create business fortunes.

Better-established companies are jumping on the bandwagon. Giant US retailer Walmart is the latest to join the fray, last month buying Kosmix, a Silicon Valley company that filters the deluge of messages on Twitter. Walmart’s understanding of its customers has hitherto been limited to data about purchasing histories and browsing habits, says Ms Ranzetta, who is a member of the Kosmix board. In future, it will be able to tap into information on their personal preferences and interests as well.

Such mining of Twitter and other social sites is being used in a wide range of industries. Roger Ehrenberg, a former hedge fund manager who invests in technology start-ups, says demand is high among financial traders for help with assembling masses of data, or for refining them so that “what’s coming through is a signal, rather than a raw feed”.

Filtering tweets in real time for practical information is one of the most challenging of these tasks, both Mr Ehrenberg and Ms Ranzetta say. Often, it is only when data from such sources are combined with other information that their value emerges.

For instance, combining details of senior management moves revealed in companies’ regulatory filings with changes to profiles on LinkedIn, the business networking site for professionals, may yield valuable insights into what is happening inside companies, says Mr Ehrenberg.

Crunching through vast data sets can reveal patterns in fields far removed from the financial markets that would not otherwise be visible. The result is the rise of techniques such as behavioural clustering (grouping people on the basis of common behavioural characteristics, rather than more traditional demographics) and look-alike marketing (marketing to a particular user based on previous successes in marketing to others with similar profiles).

Comparing people in this way may have many uses. Analysing the detailed financial behaviour of very large groups of customers over a protracted period, for instance, could give banks a clue as to which are most likely to default next, says Mr Olson at Cloudera.

Such uses of predictive analytics – a marriage of statistical modelling and data mining – raise troubling questions. Is it fair, for instance, to judge a person merely on a prediction of their future behaviour?
And what are the long-term consequences of using such analyses to categorise people ever more narrowly, shaping the types of information and advertising they are fed online? Will this lead to a form of digital determinism, in which it becomes hard to escape a life that has been preordained by some giant bank, retailer or government department?

While the use of these techniques is still in its infancy, the digital crumbs of personal information left scattered across the web are already being swept up and used with surprising results.

“If I examine any new data set, the chances are I can find something in that data that has predictive value,” says Frank Rotman, a former head of analytics at Capital One, a US financial company that was a pioneer in the field. He says existing laws about how credit decisions are made, along with current social norms, place limits on how this information is used.

The rules are laxer, however, when it comes to how credit is marketed in the first place. And, ultimately, the opacity of this largely unregulated field makes it hard to tell exactly which signals from the digital morass are being used to inform business or government decisions that have a direct bearing on many lives.

“Where it gets murky and scary is the stuff that’s being sucked out of the social system, where you have no idea how it is being used,” says Chris Larsen, chief executive of Prosper, a web service through which individuals lend to each other directly.

Innocent actions from everyday life, revealed on social networks, may become significant signals when used in a different context.

Simply failing to meet a social commitment, for instance, might turn out to be a leading indicator of a person’s reliability or otherwise as a borrower, says Mr Larsen. “There’s no question people are working on these algorithms, and trying to sell [them].”

As with many other uses of big data, the full potential of this science is still only dimly understood.
However, one thing is clear. Few consumers today are likely to welcome some of the applications that are already possible. As Mr Rotman says: “If you say you decline someone [for credit] because they have blue eyes, how will that go down?”
