The Lack of Decentralization of Data: Barriers, Exclusivity, and Monopoly in Open Data

Curated on Posted on by Stefaan Verhulst

Paper by Carla Hamida and Amanda Landi: “Recently, Facebook creator Mark Zuckerberg was on trial for the misuse of personal data. In 2013, the National Security Agency was exposed by Edward Snowden for invading the privacy of inhabitants of the United States by examining personal data. We see in the news examples, like the two just described, of government agencies and private companies being less than truthful about their use of our data. A related issue is that these same government agencies and private companies do not share their own data, and this creates the openness of data problem.

Government, academics, and citizens can play a role in making data more open. In the present, there are non-profit organizations that research data openness, such as OpenData Charter, Global Open Data Index, and Open Data Barometer. These organizations have different methods on measuring openness of data, so this leads us to question what does open data mean, how does one measure how open data is and who decides how open should data be, and to what extent society is affected by the availability, or lack of availability, of data. In this paper, we explore these questions with an examination of two of the non-profit organizations that study the open data problem extensively….(More)”.

This is how computers “predict the future”

Curated on Posted on by Stefaan Verhulst

Dan Kopf at Quartz: “The poetically named “random forest” is one of data science’s most-loved prediction algorithms. Developed primarily by statistician Leo Breiman in the 1990s, the random forest is cherished for its simplicity. Though it is not always the most accurate prediction method for a given problem, it holds a special place in machine learning because even those new to data science can implement and understand this powerful algorithm.

This was the algorithm used in an exciting 2017 study on suicide predictions, conducted by biomedical-informatics specialist Colin Walsh of Vanderbilt University and psychologists Jessica Ribeiro and Joseph Franklin of Florida State University. Their goal was to take what they knew about a set of 5,000 patients with a history of self-injury, and see if they could use those data to predict the likelihood that those patients would commit suicide. The study was done retrospectively. Sadly, almost 2,000 of these patients had killed themselves by the time the research was underway.

Altogether, the researchers had over 1,300 different characteristics they could use to make their predictions, including age, gender, and various aspects of the individuals’ medical histories. If the predictions from the algorithm proved to be accurate, the algorithm could theoretically be used in the future to identify people at high risk of suicide, and deliver targeted programs to them. That would be a very good thing.

Predictive algorithms are everywhere. In an age when data are plentiful and computing power is mighty and cheap, data scientists increasingly take information on people, companies, and markets—whether given willingly or harvested surreptitiously—and use it to guess the future. Algorithms predict what movie we might want to watch next, which stocks will increase in value, and which advertisement we’re most likely to respond to on social media. Artificial-intelligence tools, like those used for self-driving cars, often rely on predictive algorithms for decision making….(More)”.

The biggest pandemic risk? Viral misinformation

Curated on Posted on by Stefaan Verhulst

Heidi J. Larson at Nature: “A hundred years ago this month, the death rate from the 1918 influenza was at its peak. An estimated 500 million people were infected over the course of the pandemic; between 50 million and 100 million died, around 3% of the global population at the time.

A century on, advances in vaccines have made massive outbreaks of flu — and measles, rubella, diphtheria and polio — rare. But people still discount their risks of disease. Few realize that flu and its complications caused an estimated 80,000 deaths in the United States alone this past winter, mainly in the elderly and infirm. Of the 183 children whose deaths were confirmed as flu-related, 80% had not been vaccinated that season, according to the US Centers for Disease Control and Prevention.

I predict that the next major outbreak — whether of a highly fatal strain of influenza or something else — will not be due to a lack of preventive technologies. Instead, emotional contagion, digitally enabled, could erode trust in vaccines so much as to render them moot. The deluge of conflicting information, misinformation and manipulated information on social media should be recognized as a global public-health threat.

So, what is to be done? The Vaccine Confidence Project, which I direct, works to detect early signals of rumours and scares about vaccines, and so to address them before they snowball. The international team comprises experts in anthropology, epidemiology, statistics, political science and more. We monitor news and social media, and we survey attitudes. We have also developed a Vaccine Confidence Index, similar to a consumer-confidence index, to track attitudes.

Emotions around vaccines are volatile, making vigilance and monitoring crucial for effective public outreach. In 2016, our project identified Europe as the region with the highest scepticism around vaccine safety (H. J. Larson et al. EBioMedicine 12, 295–301; 2016). The European Union commissioned us to re-run the survey this summer; results will be released this month. In the Philippines, confidence in vaccine safety dropped from 82% in 2015 to 21% in 2018 (H. J. Larson et al. Hum. Vaccines Immunother. https://doi.org/10.1080/21645515.2018.1522468; 2018), after legitimate concerns arose about new dengue vaccines. Immunization rates for established vaccines for tetanus, polio, tetanus and more also plummeted.

We have found that it is useful to categorize misinformation into several levels….(More).

Challenges facing social media platforms in conflict prevention in Kenya since 2007: A case of Ushahidi platform

Curated on Posted on by Stefaan Verhulst

Paper by A.K. Njeru, B. Malakwen and M. Lumala in the International Academic Journal of Social Sciences and Education: “Throughout history information is a key factor in conflict management around the world. The media can play its important role of being the society’s watch dog of the society, by exposing to the masses what is essential but hidden, however the same media may also be used to mobilize masses to violence. Social media can therefore act as a tool for widening the democratic space, but can also lead to destabilization of peace.

The aim of the study was to establish the challenges facing social media platforms in conflict prevention in Kenya since 2007: a case of Ushahidi platform in Kenya. The paradigm that was found suitable for this study is Pragmatism. The study used a mixed approach. In this study, interviews, focus group discussions and content analysis of the Ushahidi platform were chosen as the tools of data collection. In order to bring order, structure and interpretation to the collected data, the researcher systematically organized the data by coding it into categories and constructing matrixes. After classifying the data, the researcher compared and contrasted it to the information retrieved from the literature review.

The study found that One major weak point social media as a tool for conflict prevention is the lack of ethical standards and professionalism for the users. It is too liberal and thus can be used to spread unverified information and distorted facts that might be detrimental to peace building and conflict prevention. This has led to some of the users already questioning the credibility of the information that is circulated through social media. The other weak point about social media as tool for peace building is that it is dependent to a major extent on the access to internet. The availability of internet in low units doesn’t necessarily mean cheap access. So over time the high cost of internet might affect the efficiency of the social media as a tool. The study concluded that information credibility is essential if social media as a tool is to be effective in conflict prevention and peace building.

The nature of social media which allows for anonymity of identity gives room for unverified information to be floated around the social media networks; this can be detrimental to the conflict prevention and peace building initiatives. There is therefore need for information verification and authentication by a trusted agent, to offer information appertaining to violence, conflict prevention and peace building on the social media platforms. The study recommends that Ushahidi platform should be seen as an agent of social change and should discuss the social mobilization which may be able to bring about. The study further suggest that if we can look at Ushahidi platform as a development agent, can we then take this a step further and ask, or try to find, a methodology that looks at the Ushahidi platform as peacemaking agent, or to assist in the maintenance of peace in a post-conflict thereby tapping into Ushahidi platform’s full potential….(More)”.

‘Do Not Track,’ the Privacy Tool Used by Millions of People, Doesn’t Do Anything

Curated on Posted on by Stefaan Verhulst

Kashmir Hill at Gizmodo: “When you go into the privacy settings on your browser, there’s a little option there to turn on the “Do Not Track” function, which will send an invisible request on your behalf to all the websites you visit telling them not to track you. A reasonable person might think that enabling it will stop a porn site from keeping track of what she watches, or keep Facebook from collecting the addresses of all the places she visits on the internet, or prevent third-party trackers she’s never heard of from following her from site to site. According to a recent survey by Forrester Research, a quarter of American adults use “Do Not Track” to protect their privacy. (Our own stats at Gizmodo Media Group show that 9% of visitors have it turned on.) We’ve got bad news for those millions of privacy-minded people, though: “Do Not Track” is like spray-on sunscreen, a product that makes you feel safe while doing little to actually protect you.

“Do Not Track,” as it was first imagined a decade ago by consumer advocates, was going to be a “Do Not Call” list for the internet, helping to free people from annoying targeted ads and creepy data collection. But only a handful of sites respect the request, the most prominent of which are Pinterest and Medium. (Pinterest won’t use offsite data to target ads to a visitor who’s elected not to be tracked, while Medium won’t send their data to third parties.) The vast majority of sites, including this one, ignore it….(More)”.

How pro-trust initiatives are taking over the Internet

Curated on Posted on by Stefaan Verhulst

Sara Fisher at Axios: “Dozens of new initiatives have launched over the past few years to address fake news and the erosion of faith in the media, creating a measurement problem of its own.

Why it matters: So many new efforts are launching simultaneously to solve the same problem that it’s become difficult to track which ones do what and which ones are partnering with each other….

To name a few:

  • The Trust Project, which is made up of dozens of global news companies, announced this morning that the number of journalism organizations using the global network’s “Trust Indicators” now totals 120, making it one of the larger global initiatives to combat fake news. Some of these groups (like NewsGuard) work with Trust Project and are a part of it.
  • News Integrity Initiative (Facebook, Craig Newmark Philanthropic Fund, Ford Foundation, Democracy Fund, John S. and James L. Knight Foundation, Tow Foundation, AppNexus, Mozilla and Betaworks)
  • NewsGuard (Longtime journalists and media entrepreneurs Steven Brill and Gordon Crovitz)
  • The Journalism Trust Initiative (Reporters Without Borders, and Agence France Presse, the European Broadcasting Union and the Global Editors Network )
  • Internews (Longtime international non-profit)
  • Accountability Journalism Program (American Press Institute)
  • Trusting News (Reynolds Journalism Institute)
  • Media Manipulation Initiative (Data & Society)
  • Deepnews.ai (Frédéric Filloux)
  • Trust & News Initiative (Knight Foundation, Facebook and Craig Newmark in. affiliation with Duke University)
  • Our.News (Independently run)
  • WikiTribune (Wikipedia founder Jimmy Wales)

There are also dozens of fact-checking efforts being championed by different third-parties, as well as efforts being built around blockchain and artificial intelligence.

Between the lines: Most of these efforts include some sort of mechanism for allowing readers to physically discern real journalism from fake news via some sort of badge or watermark, but that presents problems as well.

  • Attempts to flag or call out news as being real and valid have in the past been rejected even further by those who wish to discredit vetted media.
  • For example, Facebook said in December that it will no longer use “Disputed Flags” — red flags next to fake news articles — to identify fake news for users, because it found that “putting a strong image, like a red flag, next to an article may actually entrench deeply held beliefs – the opposite effect to what we intended.”…(More)”.

Study: Crowdsourced Hospital Ratings May Not Be Fair

Curated on Posted on by Stefaan Verhulst

Samantha Horton at WFYI: “Though many websites offer non-scientific ratings on a number of services, two Indiana University scientists say judging hospitals that way likely isn’t fair.

Their recently-released study compares the federal government’s Hospital Compare and crowdsourced sites such as Facebook, Yelp and Google. The research finds it’s difficult for people to accurately understand everything a hospital does, and that leads to biased ratings.

Patient experiences with food, amenities and bedside manner often aligns with federal government ratings. But IU professor Victoria Perez says judging quality of care and safety is much more nuanced and people often get it wrong.

“About 20 percent of the hospitals rated best within a local market on social media were rated worst in that market by Hospital Compare in terms of patient health outcomes,” she says.

For the crowdsourced ratings to be more useful, Perez says people would have to know how to cross-reference them with a more reliable data source, such as Hospital Compare. But even that site can be challenging to navigate depending on what the consumer is looking for.

“If you have a condition-specific concern and you can see the clinical measure for a hospital that may be helpful,” says Perez. “But if your particular medical concern is not listed there, it might be hard to extrapolate from the ones that are listed or to know which ones you should be looking at.”

She says consumers would need more information about patient outcomes and other quality metrics to be able to reliably crowdsource a hospital on a site such as Google…(More)”.

Statistics and data science degrees: Overhyped or the real deal?

Curated on Posted on by Stefaan Verhulst

 at The Conversation: “Data science” is hot right now. The number of undergraduate degrees in statistics has tripled in the past decade, and as a statistics professor, I can tell you that it isn’t because freshmen love statistics.

Way back in 2009, economist Hal Varian of Google dubbed statistician the “next sexy job.” Since then, statistician, data scientist and actuary have topped various “best jobs” lists. Not to mention the enthusiastic press coverage of industry applications: Machine learning! Big data! AI! Deep learning!

But is it good advice? I’m going to voice an unpopular opinion for the sake of starting a conversation. Stats is indeed useful, but not in the way that the popular media – and all those online data science degree programs – seem to suggest….

While all the press tends to go to the sensationalist applications – computers that watch cat videos, anyone? – the data science boom reflects a broad increase in demand for data literacy, as a baseline requirement for modern jobs.

The “big data era” doesn’t just mean large amounts of data; it also means increased ease and ability to collect data of all types, in all walks of life. Although the big five tech companies – Google, Apple, Amazon, Facebook and Microsoft – represent about 10 percent of the U.S. market cap and dominate the public imagination, they employ only one-half of one percent of all employees.

Therefore, to be a true revolution, data science will need to infiltrate nontech industries. And it is. The U.S. has seen its impact on political campaigns. I myself have consulted in the medical devices sector. A few years back, Walmart held a data analysis competition as a recruiting tool. The need for people that can dig into the data and parse it is everywhere.

In a speech at the National Academy of Sciences in 2015, Steven “Freakonomics” Levitt related his insights about the need for data-savvy workers, based on his experience as a sought-after consultant in fields ranging from the airline industry to fast food….(More)”.

Text Analysis Systems Mine Workplace Emails to Measure Staff Sentiments

Curated on Posted on by Stefaan Verhulst

Alan Rothman at LLRX: “…For all of these good, bad or indifferent workplaces, a key question is whether any of the actions of management to engage the staff and listen to their concerns ever resulted in improved working conditions and higher levels of job satisfaction?

The answer is most often “yes”. Just having a say in, and some sense of control over, our jobs and workflows can indeed have a demonstrable impact on morale, camaraderie and the bottom line. As posited in the Hawthorne Effect, also termed the “Observer Effect”, this was first discovered during studies in the 1920’s and 1930’s when the management of a factory made improvements to the lighting and work schedules. In turn, worker satisfaction and productivity temporarily increased. This was not so much because there was more light, but rather, that the workers sensed that management was paying attention to, and then acting upon, their concerns. The workers perceived they were no longer just cogs in a machine.

Perhaps, too, the Hawthorne Effect is in some ways the workplace equivalent of the Heisenberg’s Uncertainty Principle in physics. To vastly oversimplify this slippery concept, the mere act of observing a subatomic particle can change its position.¹

Giving the processes of observation, analysis and change at the enterprise level a modern (but non-quantum) spin, is a fascinating new article in the September 2018 issue of The Atlantic entitled What Your Boss Could Learn by Reading the Whole Company’s Emails, by Frank Partnoy.  I highly recommend a click-through and full read if you have an opportunity. I will summarize and annotate it, and then, considering my own thorough lack of understanding of the basics of y=f(x), pose some of my own physics-free questions….

Today the text analytics business, like the work done by KeenCorp, is thriving. It has been long-established as the processing behind email spam filters. Now it is finding other applications including monitoring corporate reputations on social media and other sites.²

The finance industry is another growth sector, as investment banks and hedge funds scan a wide variety of information sources to locate “slight changes in language” that may point towards pending increases or decreases in share prices. Financial research providers are using artificial intelligence to mine “insights” from their own selections of news and analytical sources.

But is this technology effective?

In a paper entitled Lazy Prices, by Lauren Cohen (Harvard Business School and NBER), Christopher Malloy (Harvard Business School and NBER), and Quoc Nguyen (University of Illinois at Chicago), in a draft dated February 22, 2018, these researchers found that the share price of company, in this case NetApp in their 2010 annual report, measurably went down after the firm “subtly changes” its reporting “descriptions of certain risks”. Algorithms can detect such changes more quickly and effectively than humans. The company subsequently clarified in its 2011 annual report their “failure to comply” with reporting requirements in 2010. A highly skilled stock analyst “might have missed that phrase”, but once again its was captured by “researcher’s algorithms”.

In the hands of a “skeptical investor”, this information might well have resulted in them questioning the differences in the 2010 and 2011 annual reports and, in turn, saved him or her a great deal of money. This detection was an early signal of a looming decline in NetApp’s stock. Half a year after the 2011 report’s publication, it was reported that the Syrian government has bought the company and “used that equipment to spy on its citizen”, causing further declines.

Now text analytics is being deployed at a new target: The composition of employees’ communications. Although it has been found that workers have no expectations of privacy in their workplaces, some companies remain reluctant to do so because of privacy concerns. Thus, companies are finding it more challenging to resist the “urge to mine employee information”, especially as text analysis systems continue to improve.

Among the evolving enterprise applications are the human resources departments in assessing overall employee morale. For example, Vibe is such an app that scans through communications on Slack, a widely used enterprise platform. Vibe’s algorithm, in real-time reporting, measures the positive and negative emotions of a work team….(More)”.

Renovating democracy from the bottom up

Curated on Posted on by Stefaan Verhulst

Nathan Gardels at the Washington Post: “The participatory power of social media is a game changer for governance. It levels the playing field among amateurs and experts, peers and authorities and even challenges the legitimacy of representative government. Its arrival coincides with and reinforces the widespread distrust of elites across the Western world, ripening the historical moment for direct democracy.

For the first time, an Internet-based movement has come to power in a major country, Italy, under the slogan “Participate, don’t delegate!” All of the Five Star Movement’s parliamentarians, who rule the country in a coalition with the far-right League party, were nominated and elected to stand for office online. And they have appointed the world’s first minister for direct democracy, Riccardo Fraccaro.

In Rome this week, he explained the participatory agenda of Italy’s ruling coalition government to The WorldPost at a meeting of the Global Forum on Modern Direct Democracy. “Citizens must be granted the same possibility to actively intervene in the process of managing and administrating public goods as normally carried out by their elected representatives,” he enthused. “What we have witnessed in our democracy is a drift toward ‘partyocracy,’ in which a restricted circle of policymakers have been so fully empowered with decision-making capacity that they could virtually ignore and bypass the public will. The mere election of a representative every so many years is no longer sufficient to prevent this from happening. That is why our government will take the next step forward in order to innovate and enhance our democracy.”

Fraccaro went on: “Referenda, public petitions and the citizens’ ballot initiative are nothing other than the direct means available for the citizenry to submit laws that political parties are not willing to propose or to reject rules approved by political parties that are not welcome by the people. Our aim, therefore, is to establish the principles and practices of direct democracy alongside the system of representative government in order to give real, authentic sovereignty to the citizens.”

At the Rome forum, Deputy Prime Minister Luigi di Maio, a Five Star member, railed against the technocrats and banks he says are trying to frustrate the will of the people. He promised forthcoming changes in the Italian constitution to follow through on Fraccaro’s call for citizen-initiated propositions that will go to the public ballot if the legislature does not act on them.

The program that has so far emerged out of the government’s participatory agenda is a mixed bag. It includes everything from anti-immigrant and anti-vaccine policies to the expansion of digital networks and planting more trees. In a move that has unsettled the European Union authorities as well as Italy’s non-partisan, indirectly-elected president, the governing coalition last week proposed both a tax cut and the provision of a universal basic income — despite the fact that Italy’s long-term debt is already 130 percent of GDP.

The Italian experiment warrants close attention as a harbinger of things to come elsewhere. It reveals a paradox for governance in this digital age: the more participation there is, the greater the need for the counterbalance of impartial mediating practices and institutions that can process the cacophony of voices, sort out the deluge of contested information, dispense with magical thinking and negotiate fair trade-offs among the welter of conflicting interests….(More)”.
