Verification of crowd-sourced information: is this ‘crowd wisdom’ or machine wisdom?

The problem with computer code is that it is invisible, and that it makes it easy to regulate people’s behaviour directly and often without recourse.

‘Code’ or ‘law’? Image from an Ushahidi development meetup by afropicmusing.

In ‘Code and Other Laws of Cyberspace’, Lawrence Lessig (2006) writes that computer code (or what he calls ‘West Coast code’) can have the same regulatory effect as the laws and legal code developed in Washington D.C., so-called ‘East Coast code’. Computer code impacts on a person’s behaviour by virtue of its essentially restrictive architecture: on some websites you must enter a password before you gain access, in other places you can enter unidentified. The problem with computer code, Lessig argues, is that it is invisible, and that it makes it easy to regulate people’s behaviour directly and often without recourse. For example, fair use provisions in US copyright law enable certain uses of copyrighted works, such as copying for research or teaching purposes. However the architecture of many online publishing systems heavily regulates what one can do with an e-book: how many times it can be transferred to another device, how many times it can be printed, whether it can be moved to a different format—activities that have been unregulated until now, or that are enabled by the law but effectively ‘closed off’ by code. In this case code works to reshape behaviour, upsetting the balance between the rights of copyright holders and the rights of the public to access works to support values like education and innovation. Working as an ethnographic researcher for Ushahidi, the non-profit technology company that makes tools for people to crowdsource crisis information, has made me acutely aware of the many ways in which ‘code’ can become ‘law’. During my time at Ushahidi, I studied the practices that people were using to verify reports by people affected by a variety of events—from earthquakes to elections, from floods to bomb blasts. I then compared these processes with those followed by Wikipedians when editing articles about breaking news events. In order to understand how to best design architecture to enable particular behaviour, it becomes important to…

Exploring variation in parental concerns about online safety issues

by David Sutcliffe 14/11/2013

Parents have different and often conflicting views about what’s best for their children. What’s helpful to one group of parents may not actually benefit parents or youth as a whole.

by David Sutcliffe 14/11/2013

Ed: You’ve spent a great deal of time studying the way that children and young people use the Internet, much of which focuses on the positive experiences that result. Why do you think this is so under-represented in public debate? boyd/Hargittai: The public has many myths about young people’s use of technology. This is often perpetuated by media coverage that focuses on the extremes. Salacious negative headlines often capture people’s attention, even if the practices or incidents described are outliers and do not represent the majority’s experiences. While focusing on extremely negative and horrific incidents is a great way to attract attention and get readers, it does a disservice to young people, their parents, and ultimately society as a whole. As researchers, we believe that it’s important to understand the nuances of what people experience when they engage with technology. Thus, we are interested in gaining a better understanding of their everyday practices—both the good and the bad. Our goal is to introduce research that can help contextualise socio-technical practices and provide insight into the diversity of viewpoints and perspectives that shape young people’s use of technology. Ed: Your paper suggests we need a more granular understanding of how parental concerns relating to the Internet can vary across different groups. Why is this important? What are the main policy implications of this research? boyd/Hargittai: Parents are often seen as the target of policy interventions. Many lawmakers imagine that they’re designing laws to help empower parents, but when you ask them to explain which parents they are empowering, it becomes clear that there’s an imagined parent that is not always representative of the diverse views and perspectives of all parents. We’re not opposed to laws that enable parents to protect their children, but we’re concerned whenever a class of people, especially a class as large as “parents,” is viewed as homogenous. Parents have different and often conflicting views about what’s best…

Ethical privacy guidelines for mobile connectivity measurements

Measuring the mobile Internet can expose information about an individual’s location, contact details, and communications metadata.

Ed: GCHQ / the NSA aside, who collects mobile data and for what purpose? How can you tell if your data are being collected and passed on? Ben: Data collected from mobile phones is used for a wide range of (divergent) purposes. First and foremost, mobile operators need information about mobile phones in real-time to be able to communicate with individual mobile handsets. Apps can also collect all sorts of information, which may be necessary to provide entertainment, location specific services, to conduct network research and many other reasons. Mobile phone users usually consent to the collection of their data by clicking “I agree” or other legally relevant buttons, but this is not always the case. Sometimes data is collected lawfully without consent, for example for the provision of a mobile connectivity service. Other times it is harder to substantiate a relevant legal basis. Many applications keep track of the information that is generated by a mobile phone and it is often not possible to find out how the receiver processes this data. Ed: How are data subjects typically recruited for a mobile research project? And how many subjects might a typical research data set contain? Ben: This depends on the research design; some research projects provide data subjects with a specific app, which they can use to conduct measurements (so called ‘active measurements’). Other apps collect data in the background and, in effect, conduct local surveillance of the mobile phone use (so called passive measurements). Other research uses existing datasets, for example provided by telecom operators, which will generally be de-identified in some way. We purposely do not use the term anonymisation in the report, because much research and several case studies have shown that real anonymisation is very difficult to achieve if the original raw data is collected about individuals. Datasets can be re-identified by techniques such as fingerprinting or by linking them with existing, auxiliary datasets. The size…

Five recommendations for maximising the relevance of social science research for public policy-making in the big data era

by Helen Margetts 04/11/2013 1 Comment

How can social scientists help policy-makers in this changed environment, ensuring that social science research remains relevant?

by Helen Margetts 04/11/2013 1 Comment

As I discussed in a previous post on the promises and threats of big data for public policy-making, public policy making has entered a period of dramatic change. Widespread use of digital technologies, the Internet and social media means citizens and governments leave digital traces that can be harvested to generate big data. This increasingly rich data environment poses both promises and threats to policy-makers. So how can social scientists help policy-makers in this changed environment, ensuring that social science research remains relevant? Social scientists have a good record on having policy influence, indeed in the UK better than other academic fields, including medicine, as recent research from the LSE Public Policy group has shown. Big data hold major promise for social science, which should enable us to further extend our record in policy research. We have access to a cornucopia of data of a kind which is more like that traditionally associated with so-called ‘hard’ science. Rather than being dependent on surveys, the traditional data staple of empirical social science, social media such as Wikipedia, Twitter, Facebook, and Google Search present us with the opportunity to scrape, generate, analyse and archive comparative data of unprecedented quantity. For example, at the OII over the last four years we have been generating a dataset of all petition signing in the UK and US, which contains the joining rate (updated every hour) for the 30,000 petitions created in the last three years. As a political scientist, I am very excited by this kind of data (up to now, we have had big data like this only for voting, and that only at election time), which will allow us to create a complete ecology of petition signing, one of the more popular acts of political participation in the UK. Likewise, we can look at the entire transaction history of online organisations like Wikipedia, or map the link structure of government’s online presence. But…

The promises and threats of big data for public policy-making

by Helen Margetts 28/10/2013

Widespread use of digital technologies, the Internet and social media means both citizens and governments leave digital traces that can be harvested to generate big data.

by Helen Margetts 28/10/2013

The environment in which public policy is made has entered a period of dramatic change. Widespread use of digital technologies, the Internet and social media means both citizens and governments leave digital traces that can be harvested to generate big data. Policy-making takes place in an increasingly rich data environment, which poses both promises and threats to policy-makers. On the promise side, such data offers a chance for policy-making and implementation to be more citizen-focused, taking account of citizens’ needs, preferences and actual experience of public services, as recorded on social media platforms. As citizens express policy opinions on social networking sites such as Twitter and Facebook; rate or rank services or agencies on government applications such as NHS Choices; or enter discussions on the burgeoning range of social enterprise and NGO sites, such as Mumsnet, 38 degrees and patientopinion.org, they generate a whole range of data that government agencies might harvest to good use. Policy-makers also have access to a huge range of data on citizens’ actual behaviour, as recorded digitally whenever citizens interact with government administration or undertake some act of civic engagement, such as signing a petition. Data mined from social media or administrative operations in this way also provide a range of new data which can enable government agencies to monitor—and improve—their own performance, for example through log usage data of their own electronic presence or transactions recorded on internal information systems, which are increasingly interlinked. And they can use data from social media for self-improvement, by understanding what people are saying about government, and which policies, services or providers are attracting negative opinions and complaints, enabling identification of a failing school, hospital or contractor, for example. They can solicit such data via their own sites, or those of social enterprises. And they can find out what people are concerned about or looking for, from the Google Search API or Google trends, which record the search…

Can text mining help handle the data deluge in public policy analysis?

by Aude Bicquelet 27/10/2013

There has been a major shift in the policies of governments concerning participatory governance—that is, engaged, collaborative, and community-focused public policy.

by Aude Bicquelet 27/10/2013

Policy makers today must contend with two inescapable phenomena. On the one hand, there has been a major shift in the policies of governments concerning participatory governance—that is, engaged, collaborative, and community-focused public policy. At the same time, a significant proportion of government activities have now moved online, bringing about “a change to the whole information environment within which government operates” (Margetts 2009, 6). Indeed, the Internet has become the main medium of interaction between government and citizens, and numerous websites offer opportunities for online democratic participation. The Hansard Society, for instance, regularly runs e-consultations on behalf of UK parliamentary select committees. For examples, e-consultations have been run on the Climate Change Bill (2007), the Human Tissue and Embryo Bill (2007), and on domestic violence and forced marriage (2008). Councils and boroughs also regularly invite citizens to take part in online consultations on issues affecting their area. The London Borough of Hammersmith and Fulham, for example, recently asked its residents for thier views on Sex Entertainment Venues and Sex Establishment Licensing policy. However, citizen participation poses certain challenges for the design and analysis of public policy. In particular, governments and organisations must demonstrate that all opinions expressed through participatory exercises have been duly considered and carefully weighted before decisions are reached. One method for partly automating the interpretation of large quantities of online content typically produced by public consultations is text mining. Software products currently available range from those primarily used in qualitative research (integrating functions like tagging, indexing, and classification), to those integrating more quantitative and statistical tools, such as word frequency and cluster analysis (more information on text mining tools can be found at the National Centre for Text Mining). While these methods have certainly attracted criticism and skepticism in terms of the interpretability of the output, they offer four important advantages for the analyst: namely categorisation, data reduction, visualisation, and speed. 1. Categorisation. When analysing the results…

Can Twitter provide an early warning function for the next pandemic?

by Patty Kostkova 14/10/2013

While traditional surveillance systems will remain the pillars of public health, online media monitoring has added an important early-warning function, with social media bringing additional benefits to epidemic intelligence.

by Patty Kostkova 14/10/2013

Communication of risk in any public health emergency is a complex task for healthcare agencies; a task made more challenging when citizens are bombarded with online information. Mexico City, 2009. Image by Eneas.

Ed: Could you briefly outline your study? Patty: We investigated the role of Twitter during the 2009 swine flu pandemics from two perspectives. Firstly, we demonstrated the role of the social network to detect an upcoming spike in an epidemic before the official surveillance systems—up to week in the UK and up to 2-3 weeks in the US—by investigating users who “self-diagnosed” themselves posting tweets such as “I have flu/swine flu.” Secondly, we illustrated how online resources reporting the WHO declaration of “pandemics” on 11 June 2009 were propagated through Twitter during the 24 hours after the official announcement [1,2,3]. Ed: Disease control agencies already routinely follow media sources; are public health agencies aware of social media as another valuable source of information? Patty: Social media are providing an invaluable real-time data signal complementing well-established epidemic intelligence (EI) systems monitoring online media, such as MedISys and GPHIN. While traditional surveillance systems will remain the pillars of public health, online media monitoring has added an important early-warning function, with social media bringing additional benefits to epidemic intelligence: virtually real-time information available in the public domain that is contributed by users themselves, thus not relying on the editorial policies of media agencies. Public health agencies (such as the European Centre for Disease Prevention and Control) are interested in social media early warning systems, but more research is required to develop robust social media monitoring solutions that are ready to be integrated with agencies’ EI services. Ed: How difficult is this data to process? E.g.: is this a full sample, processed in real-time? Patty: No, obtaining all Twitter search query results is not possible. In our 2009 pilot study we were accessing data from Twitter using a search API interface querying the database every minute (the number of results was limited to 100 tweets). Currently, only 1% of the ‘Firehose’ (massive real-time stream of all public tweets) is made available using the streaming API. The searches have…

Who represents the Arab world online?

by Mark Graham 01/10/2013

The Middle East and North Africa are relatively under-represented in Wikipedia. Even after accounting for factors like population, Internet access, and literacy, we still see less contact than would be expected.

by Mark Graham 01/10/2013

Editors from all over the world have played some part in writing about Egypt; in fact, only 13% of all edits actually originate in the country (38% are from the US). More: Who edits Wikipedia? by Mark Graham. Ed: In basic terms, what patterns of ‘information geography’ are you seeing in the region? Mark: The first pattern that we see is that the Middle East and North Africa are relatively under-represented in Wikipedia. Even after accounting for factors like population, Internet access, and literacy, we still see less contact than would be expected. Second, of the content that exists, a lot of it is in European and French rather than in Arabic (or Farsi or Hebrew). In other words, there is even less in local languages. And finally, if we look at contributions (or edits), not only do we also see a relatively small number of edits originating in the region, but many of those edits are being used to write about other parts of the word rather than their own region. What this broadly seems to suggest is that the participatory potentials of Wikipedia aren’t yet being harnessed in order to even out the differences between the world’s informational cores and peripheries. Ed: How closely do these online patterns in representation correlate with regional (offline) patterns in income, education, language, access to technology (etc.) Can you map one to the other? Mark: Population and broadband availability alone explain a lot of the variance that we see. Other factors like income and education also play a role, but it is population and broadband that have the greatest explanatory power here. Interestingly, it is most countries in the MENA region that fail to fit well to those predictors. Ed: How much do you think these patterns result from the systematic imposition of a particular view point—such as official editorial policies—as opposed to the (emergent) outcome of lots of users and editors…

Responsible research agendas for public policy in the era of big data

by Vicki Nash 19/09/2013

Bringing together leading social science academics with senior government agency staff to discuss its public policy potential.

by Vicki Nash 19/09/2013

Last week the OII went to Harvard. Against the backdrop of a gathering storm of interest around the potential of computational social science to contribute to the public good, we sought to bring together leading social science academics with senior government agency staff to discuss its public policy potential. Supported by the OII-edited journal Policy and Internet and its owners, the Washington-based Policy Studies Organization (PSO), this one-day workshop facilitated a thought-provoking conversation between leading big data researchers such as David Lazer, Brooke Foucault-Welles and Sandra Gonzalez-Bailon, e-government experts such as Cary Coglianese, Helen Margetts and Jane Fountain, and senior agency staff from US federal bureaus including Labor Statistics, Census, and the Office for the Management of the Budget. It’s often difficult to appreciate the impact of research beyond the ivory tower, but what this productive workshop demonstrated is that policy-makers and academics share many similar hopes and challenges in relation to the exploitation of ‘big data’. Our motivations and approaches may differ, but insofar as the youth of the ‘big data’ concept explains the lack of common language and understanding, there is value in mutual exploration of the issues. Although it’s impossible to do justice to the richness of the day’s interactions, some of the most pertinent and interesting conversations arose around the following four issues. Managing a diversity of data sources. In a world where our capacity to ask important questions often exceeds the availability of data to answer them, many participants spoke of the difficulties of managing a diversity of data sources. For agency staff this issue comes into sharp focus when available administrative data that is supposed to inform policy formulation is either incomplete or inadequate. Consider, for example, the challenge of regulating an economy in a situation of fundamental data asymmetry, where private sector institutions track, record and analyse every transaction, whilst the state only has access to far more basic performance metrics and accounts.…

Is China shaping the Internet in Africa?

by Iginio Gagliardone 15/08/2013

Concerns have been expressed about the detrimental role China may play in African media sectors, by increasing authoritarianism and undermining Western efforts to promote openness and freedom of expression.

by Iginio Gagliardone 15/08/2013

CAPE TOWNSOUTH AFRICA, 06MAY11 - The Panel during the Future of China-Africa Relations session held at World Economic Forum on Africa 2011 held in Cape Town, South Africa, 4-6 May 2011. Copyright (cc-by-sa) © World Economic Forum (www.weforum.org/Photo Eric Miller emiller@iafrica.com

Ed: Concerns have been expressed (e.g. by Hillary Clinton and David Cameron) about the detrimental role China may play in African media sectors, by increasing authoritarianism and undermining Western efforts to promote openness and freedom of expression. Are these concerns fair? Iginio: China’s initiatives in the communication sector abroad are burdened by the negative record of its domestic media. For the Chinese authorities this is a challenge that does not have an easy solution as they can’t really use their international broadcasters to tell a different story about Chinese media and Chinese engagement with foreign media, because they won’t be trusted. As the linguist George Lakoff has explained, if someone is told “Don’t think of an elephant!” he will likely start “summoning the bulkiness, the grayness, the trunkiness of an elephant”. That is to say, “when we negate a frame, we evoke a frame.” Saying that “Chinese interventions are not increasing authoritarianism” won’t help much. The only path China can undertake is to develop projects and use its media in ways that fall outside the realm of what is expected, creating new associations between China and the media, rather than trying to redress existing ones. In part this is already happening. For example, CCTV Africa, the new initiative of state-owned China’s Central Television (CCTV) and China’s flagship effort to win African hearts and minds, has developed a strategy aimed not at directly offering an alternative image of China, but at advancing new ways of looking at Africa, offering unprecedented resources to African journalists to report from the continent and tapping into the narrative of a “rising Africa,” as a continent of opportunities rather than of hunger, wars and underdevelopment. Ed: Ideology has disappeared from the language of China-Africa cooperation, largely replaced by admissions of China’s interest in Africa’s resources and untapped potential. Does politics (e.g. China wanting to increase its international support and influence) nevertheless still inform the relationship? China’s…
