Facebook Data for Good

Curated on Posted on by Stefaan Verhulst

Foreword by Sheryl Sandberg: “When Facebook launched the Data for Good program in 2017, we never imagined it would play a role so soon in response to a truly global emergency. The COVID-19 pandemic is not just a public health crisis, but also a social and economic one. It has caused hardship in every part of the world, but its impact hasn’t been felt equally. It has hit women and the most disadvantaged communities the hardest – something this work has helped shine a light on.

In response to the pandemic, Facebook has been part of an unprecedented collaboration between technology companies, the public sector, universities, nonprofits and others. Our partners operate in some of the most challenging environments in the world, where lengthy analysis and debate is often a luxury they don’t have. The policies that govern delivery of vaccines, masks, and financial support can mean the difference between life and death. By sharing tools that provide real-time insights, Facebook can make decision-making on the ground just a little bit easier and more effective.

This report highlights some of the ways Facebook data – shared in a way that protects the privacy of individuals – assisted the response efforts to the pandemic and other major crises in 2020. I hope the examples included help illustrate what successful data sharing projects can look like, and how future projects can be improved. Above all, I hope we can continue to work together in 2021 and beyond to save lives and mitigate the damage caused by the pandemic and any crises that may follow….(More)”.

Enabling the future of academic research with the Twitter API

Curated on Posted on by Stefaan Verhulst

Twitter Developer Blog: “When we introduced the next generation of the Twitter API in July 2020, we also shared our plans to invest in the success of the academic research community with tailored solutions that better serve their goals. Today, we’re excited to launch the Academic Research product track on the new Twitter API. 

Why we’re launching this & how we got here

Since the Twitter API was first introduced in 2006, academic researchers have used data from the public conversation to study topics as diverse as the conversation on Twitter itself – from state-backed efforts to disrupt the public conversation to floods and climate change, from attitudes and perceptions about COVID-19 to efforts to promote healthy conversation online. Today, academic researchers are one of the largest groups of people using the Twitter API. 

Our developer platform hasn’t always made it easy for researchers to access the data they need, and many have had to rely on their own resourcefulness to find the right information. Despite this, for over a decade, academic researchers have used Twitter data for discoveries and innovations that help make the world a better place.

Over the past couple of years, we’ve taken iterative steps to improve the experience for researchers, like when we launched a webpage dedicated to Academic Research, and updated our Twitter Developer Policy to make it easier to validate or reproduce others’ research using Twitter data.

We’ve also made improvements to help academic researchers use Twitter data to advance their disciplines, answer urgent questions during crises, and even help us improve Twitter. For example, in April 2020, we released the COVID-19 stream endpoint – the first free, topic-based stream built solely for researchers to use data from the global conversation for the public good. Researchers from around the world continue to use this endpoint for a number of projects.

Over two years ago, we started our own extensive research to better understand the needs, constraints and challenges that researchers have when studying the public conversation. In October 2020, we tested this product track in a private beta program where we gathered additional feedback. This gave us a glimpse into some of the important work that the free Academic Research product track we’re launching today can now enable….(More)”.

Facebook will let researchers study how advertisers targeted users with political ads prior to Election Day

Curated on Posted on by Stefaan Verhulst

Nick Statt at The Verge: “Facebook is aiming to improve transparency around political advertising on its platform by opening up more data to independent researchers, including targeting information on more than 1.3 million ads that ran in the three months prior to the US election on November 3rd of last year. Researchers interested in studying the ads can apply for access to the Facebook Open Research and Transparency (FORT) platform here.

The move is significant because Facebook has long resisted willfully allowing access to data around political advertising, often citing user privacy. The company has gone so far as to even disable third-party web plugins, like ProPublica’s Facebook Political Ad Collector tool, that collect such data without Facebook’s express consent.

Numerous research groups around the globe have spent years now studying Facebook’s impact on everything from democratic elections to news dissemination, but sometimes without full access to all the desired data. Only last year, after partnering with Harvard University’s Social Science One (the group overseeing applications for the new political ad targeting initiative), did Facebook better formalize the process of granting anonymized user data for research studies.

In the past, Facebook has made some crucial political ad information in its Ad Library available to the public, including the amount spent on certain ads and demographic information about who saw those ads. But now the company says it wants to do more to improve transparency, specifically around how advertisers target certain subsets of users with political advertising….(More)”.

The High Price of Mistrust

Curated on Posted on by Stefaan Verhulst

fs.blog: “There are costs to falling community participation. Rather than simply lamenting the loss of a past golden era (as people have done in every era), Harvard political scientist Robert D. Putnam explains these costs, as well as how we might bring community participation back.

First published twenty years ago, Bowling Alone is an exhaustive, hefty work. In its 544 pages, Putnam negotiated mountains of data to support his thesis that the previous few decades had seen Americans retreat en masse from public life. Putnam argued Americans had become disconnected from their wider communities, as evidenced by changes such as a decline in civic engagement and dwindling membership rates for groups such as bowling leagues and PTAs.

Though aspects of Bowling Alone are a little dated today (“computer-mediated communication” isn’t a phrase you’re likely to have heard recently), a quick glance at 2021’s social landscape would suggest many of the trends Putnam described have only continued and apply in other parts of the world too.

Right now, polarization and social distancing have forced us apart from any sense of community to a degree that can seem irresolvable.

Will we ever bowl in leagues alongside near strangers and turn them into friends again? Will we ever bowl again at all, even if alone, or will those gleaming aisles, too-tight shoes, and overpriced sodas fade into a distant memory we recount to our children?

The idea of going into a public space for a non-essential reason can feel incredibly out of reach for many of us right now. And who knows how spaces like bowling alleys will survive in the long run without the social scenes that fuelled them. Now is a perfect time to revisit Bowling Alone to see what it can still teach us, because many of its warnings and lessons are perhaps more relevant now than at its time of publication.

One key lesson we can derive from Bowling Alone is that the less we trust each other—something which is both a cause and consequence of declining community engagement—the more it costs us. Mistrust is expensive.…(More)”

These crowdsourced maps will show exactly where surveillance cameras are watching

Curated on Posted on by Stefaan Verhulst

Mark Sullivan at FastCompany: “Amnesty International is producing a map of all the places in New York City where surveillance cameras are scanning residents’ faces.

The project will enlist volunteers to use their smartphones to identify, photograph, and locate government-owned surveillance cameras capable of shooting video that could be matched against people’s faces in a database through AI-powered facial recognition.

The map that will eventually result is meant to give New Yorkers the power of information against an invasive technology the usage of which and purpose is often not fully disclosed to the public. It’s also meant to put pressure on the New York City Council to write and pass a law restricting or banning it. Other U.S. cities, such as Boston, Portland, and San Francisco, have already passed such laws.

Facial recognition technology can be developed by scraping millions of images from social media profiles and driver’s licenses without people’s consent, Amnesty says. Software from companies like Clearview AI can then use computer vision algorithms to match those images against facial images captured by closed-circuit television (CCTV) or other video surveillance cameras and stored in a database.

Starting in May, volunteers will be able to use a software tool to identify all the facial recognition cameras within their view—like at an intersection where numerous cameras can often be found. The tool, which runs on a phone’s browser, lets users place a square around any cameras they see. The software integrates Google Street View and Google Earth to help volunteers label and attach geolocation data to the cameras they spot.

The map is part of a larger campaign called “Ban the Scan” that’s meant to educate people around the world on the civil rights dangers of facial recognition. Research has shown that facial recognition systems aren’t as accurate when it comes to analyzing dark-skinned faces, putting Black people at risk of being misidentified. Even when accurate, the technology exacerbates systemic racism because it is disproportionately used to identify people of color, who are already subject to discrimination by law enforcement officials. The campaign is sponsored by Amnesty in partnership with a number of other tech advocacy, privacy, and civil liberties groups.

In the initial phase of the project, which was announced last Thursday, Amnesty and its partners launched a website that New Yorkers can use to generate public comments on the New York Police Department’s (NYPD’s) use of facial recognition….(More)”.

Twitter’s misinformation problem is much bigger than Trump. The crowd may help solve it.

Curated on Posted on by Stefaan Verhulst

Elizabeth Dwoskin at the Washington Post: “A pilot program called Birdwatch lets selected users write corrections and fact checks on potentially misleading tweets…

The presidential election is over, but the fight against misinformation continues.

The latest volley in that effort comes from Twitter, which on MondayannouncedBirdwatch, a pilot project that uses crowdsourcing techniques to combat falsehoods and misleading statements on its service.

The pilot, which is open to only about 1,000 select users who can apply to be contributors, will allow people to write notes with corrections and accurate information directly into misleading tweets — a method that has the potential to get quality information to people more quickly than traditional fact-checking. Fact checks that are rated by other contributors as high quality may get bumped up or rewarded with greater visibility.

Birdwatch represents Twitter’s most experimental response to one of the biggest lessons that social media companies drew from the historic events of 2020: that their existing efforts to combat misinformation — including labeling, fact-checking and sometimes removing content — were not enough to prevent falsehoods about a stolen election or the coronavirus from reaching and influencing broad swaths of the population. Researchers who studied enforcement actions by social media companies last year found that fact checks and labels are usually implemented too late, after a post or a tweet has gone viral.

The Birdwatch project — which for the duration of the pilot will function as a separate website — is novel in that it attempts to build new mechanisms into Twitter’s product that foreground fact-checking by its community of 187 million daily users worldwide. Rather than having to comb through replies to tweets to sift through what’s true or false — or having Twitter employees append to a tweet a label providing additional context — users will be able to click on a separate notes folder attached to a tweet where they can see the consensus-driven responses from the community. Twitter will have a team reviewing winning responses to prevent manipulation, though a major question is whether any part of the process will be automated and therefore more easily gamed….(More)”

Sharing Student Health Data with Health Agencies: Considerations and Recommendations

Curated on Posted on by Stefaan Verhulst

Memo by the Center for Democracy and Technology: “As schools respond to COVID-19 on their campuses, some have shared student information with state and local health agencies, often to aid in contact tracing or to provide services to students. Federal and state student privacy laws, however, do not necessarily permit that sharing, and schools should seek to protect both student health and student privacy.

How Are Schools Sharing COVID-Related Student Data?

When it comes to sharing student data, schools’ practices vary widely. For example, the New York City Department of Education provides a consent form for sharing COVID-related student data. Other schools do not have consent forms, but instead, share COVID-related data as required by local or state health agencies. For instance, Orange County Public Schools in Florida assists the local health agency in contact tracing by collecting information such as students’ names and dates of birth. Some districts, such as the Dallas Independent School District in Texas, report positive cases to the county, but do not publicly specify what information is reported. Many schools, however, do not publicly disclose their collection and sharing of COVID-related student data….(More)”

A recommendation and risk classification system for connecting rough sleepers to essential outreach services

Curated on Posted on by Stefaan Verhulst

Paper by Harrison Wilde et al: “Rough sleeping is a chronic experience faced by some of the most disadvantaged people in modern society. This paper describes work carried out in partnership with Homeless Link (HL), a UK-based charity, in developing a data-driven approach to better connect people sleeping rough on the streets with outreach service providers. HL’s platform has grown exponentially in recent years, leading to thousands of alerts per day during extreme weather events; this overwhelms the volunteer-based system they currently rely upon for the processing of alerts. In order to solve this problem, we propose a human-centered machine learning system to augment the volunteers’ efforts by prioritizing alerts based on the likelihood of making a successful connection with a rough sleeper. This addresses capacity and resource limitations whilst allowing HL to quickly, effectively, and equitably process all of the alerts that they receive. Initial evaluation using historical data shows that our approach increases the rate at which rough sleepers are found following a referral by at least 15% based on labeled data, implying a greater overall increase when the alerts with unknown outcomes are considered, and suggesting the benefit in a trial taking place over a longer period to assess the models in practice. The discussion and modeling process is done with careful considerations of ethics, transparency, and explainability due to the sensitive nature of the data involved and the vulnerability of the people that are affected….(More)”.

Citizen acceptance of mass surveillance? Identity, intelligence, and biodata concerns

Curated on Posted on by Stefaan Verhulst

Paper by Westerlund, Mika; Isabelle, Diane A; Leminen, Seppo: “News media and human rights organizations are warning about the rise of the surveillance state that builds on distrust and mass surveillance of its citizens. Further, the global pandemic has fostered public-private collaboration such as the launch of contact tracing apps to tackle COVID-19. Thus, such apps also contribute to the diffusion of technologies that can collect and analyse large amounts of sensitive data and the growth of the surveillance society. This study examines the impacts of citizens’ concerns about digital identity, government’s intelligence activities, and security of the increasing biodata on their trust in and acceptance of government’s use of personal data. Our analysis of survey data from 1,486 Canadians suggest that those concerns have direct effects on people’s acceptance of government’s use of personal data, but not necessarily on the trust in the government being respectful of privacy. Authorities should be more transparent about the collection and uses of data….(More)”

Consensus or chaos? Pandemic response hinges on trust, experts say

Curated on Posted on by Stefaan Verhulst

Article by Catherine Cheney: “Trust is a key reason for the wide variance in how countries have fared during the COVID-19 pandemic, determining why some have succeeded in containing the virus while others have failed, according to new research on responses across 23 countries.

The work, supported by Schmidt Futures and the National Science Foundation and carried out by teams at Columbia, Harvard, and Cornell Universities, studied national responses to COVID-19 based on public health, economy, and politics.

It organizes countries into three categories: control, consensus, and chaos. The researchers call the United States the leading example of high levels of polarization, decentralized decision-making, and distrust in expertise leading to policy chaos. The category also includes Brazil, India, Italy, and the United Kingdom.

To prepare for future pandemics, countries must build trust in public health, government institutions, and expert advice, according to a range of speakers at last week’s Futures Forum on Preparedness. Schmidt Futures, which co-hosted the event, announced that it is launching a new challenge to source the best ideas from around the world for developing trust in public health interventions. This request for proposals is likely just the beginning as funders explore how to learn from the pandemic and build trust moving forward….(More)”.
