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…

Predicting elections on Twitter: a different way of thinking about the data

by Nick Anstead 04/08/2013

Social media monitoring, which in theory can extract information from tweets and Facebook posts and quantify positive and negative public reactions to people, policies and events has an obvious utility for politicians seeking office.

Recently, there has been a lot of interest in the potential of social media as a means to understand public opinion. Driven by an interest in the potential of so-called “big data”, this development has been fuelled by a number of trends. Governments have been keen to create techniques for what they term “horizon scanning”, which broadly means searching for the indications of emerging crises (such as runs on banks or emerging natural disasters) online, and reacting before the problem really develops. Governments around the world are already committing massive resources to developing these techniques. In the private sector, big companies’ interest in brand management has fitted neatly with the potential of social media monitoring. A number of specialised consultancies now claim to be able to monitor and quantify reactions to products, interactions or bad publicity in real time. It should therefore come as little surprise that, like other research methods before, these new techniques are now crossing over into the competitive political space. Social media monitoring, which in theory can extract information from tweets and Facebook posts and quantify positive and negative public reactions to people, policies and events has an obvious utility for politicians seeking office. Broadly, the process works like this: vast datasets relating to an election, often running into millions of items, are gathered from social media sites such as Twitter. These data are then analysed using natural language processing software, which automatically identifies qualities relating to candidates or policies and attributes a positive or negative sentiment to each item. Finally, these sentiments and other properties mined from the text are totalised, to produce an overall figure for public reaction on social media. These techniques have already been employed by the mainstream media to report on the 2010 British general election (when the country had its first leaders debate, an event ripe for this kind of research) and also in the 2012 US presidential election.

Investigating the structure and connectivity of online global protest networks

by Sandra Gonzalez-Bailon 10/06/2013

The new networks of political protest, which harness these new online technologies are often described in theoretical terms as being ‘fluid’ and ‘horizontal’, in contrast to the rigid and hierarchical structure of earlier protest organisation.

by Sandra Gonzalez-Bailon 10/06/2013

How have online technologies reconfigured collective action? It is often assumed that the rise of social networking tools, accompanied by the mass adoption of mobile devices, have strengthened the impact and broadened the reach of today’s political protests. Enabling massive self-communication allows protesters to write their own interpretation of events—free from a mass media often seen as adversarial—and emerging protests may also benefit from the cheaper, faster transmission of information and more effective mobilisation made possible by online tools such as Twitter. The new networks of political protest, which harness these new online technologies are often described in theoretical terms as being ‘fluid’ and ‘horizontal’, in contrast to the rigid and hierarchical structure of earlier protest organisation. Yet such theoretical assumptions have seldom been tested empirically. This new language of networks may be useful as a shorthand to describe protest dynamics, but does it accurately reflect how protest networks mediate communication and coordinate support? The global protests against austerity and inequality which took place on May 12, 2012 provide an interesting case study to test the structure and strength of a transnational online protest movement. The ‘indignados’ movement emerged as a response to the Spanish government’s politics of austerity in the aftermath of the global financial crisis. The movement flared in May 2011, when hundreds of thousands of protesters marched in Spanish cities, and many set up camps ahead of municipal elections a week later. These protests contributed to the emergence of the worldwide Occupy movement. After the original plan to occupy New York City’s financial district mobilised thousands of protesters in September 2011, the movement spread to other cities in the US and worldwide, including London and Frankfurt, before winding down as the camp sites were dismantled weeks later. Interest in these movements was revived, however, as the first anniversary of the ‘indignados’ protests approached in May 2012. To test whether the fluidity, horizontality and connectivity often claimed for…

Why do (some) political protest mobilisations succeed?

by Sandra Gonzalez-Bailon 19/04/2013

Mobilisation paths are difficult to predict because they depend on the right alignment of conditions on different levels.

by Sandra Gonzalez-Bailon 19/04/2013

The communication technologies once used by rebels and protesters to gain global visibility now look burdensome and dated: much separates the once-futuristic-looking image of Subcomandante Marcos posing in the Chiapas jungle draped in electronic gear (1994) from the uprisings of the 2011 Egyptian revolution. While the only practical platform for amplifying a message was once provided by organisations, the rise of the Internet means that cross-national networks are now reachable by individuals—who are able to bypass organisations, ditch membership dues, and embrace self-organisation. As social media and mobile applications increasingly blur the distinction between public and private, ordinary citizens are becoming crucial nodes in the contemporary protest network. The personal networks that are the main channels of information flow in sites such as Facebook, Twitter and LinkedIn mean that we don’t need to actively seek out particular information; it can be served to us with no more effort than that of maintaining a connection with our contacts. News, opinions, and calls for justice are now shared and forwarded by our friends—and their friends—in a constant churn of information, all attached to familiar names and faces. Given we are more likely to pass on information if the source belongs to our social circle, this has had an important impact on the information environment within which protest movements are initiated and develop. Mobile connectivity is also important for understanding contemporary protest, given that the ubiquitous streams of synchronous information we access anywhere are shortening our reaction times. This is important, as the evolution of mass recruitments—whether they result in flash mobilisations, slow burns, or simply damp squibs—can only be properly understood if we have a handle on the distribution of reaction times within a population. The increasing integration of the mainstream media into our personal networks is also important, given that online networks (and independent platforms like Indymedia) are not the clear-cut alternative to corporate media they once were. We can now…

Did Libyan crisis mapping create usable military intelligence?

by Steve Stottlemyre 14/03/2013

While many people continued to contribute conventional humanitarian information to the map, the sudden shift toward information that could aid international military intervention was unmistakable.

by Steve Stottlemyre 14/03/2013

The Middle East has recently witnessed a series of popular uprisings against autocratic rulers. In mid-January 2011, Tunisian President Zine El Abidine Ben Ali fled his country, and just four weeks later, protesters overthrew the regime of Egyptian President Hosni Mubarak. Yemen’s government was also overthrown in 2011, and Morocco, Jordan, and Oman saw significant governmental reforms leading, if only modestly, toward the implementation of additional civil liberties. Protesters in Libya called for their own ‘day of rage’ on February 17, 2011, marked by violent protests in several major cities, including the capitol Tripoli. As they transformed from ‘protestors’ to ‘Opposition forces’ they began pushing information onto Twitter, Facebook, and YouTube, reporting their firsthand experiences of what had turned into a civil war virtually overnight. The evolving humanitarian crisis prompted the United Nations to request the creation of the Libya Crisis Map, which was made public on March 6, 2011. Other, more focused crisis maps followed, and were widely distributed on Twitter. While the map was initially populated with humanitarian information pulled from the media and online social networks, as the imposition of an internationally enforced No Fly Zone (NFZ) over Libya became imminent, information began to appear on it that appeared to be of a tactical military nature. While many people continued to contribute conventional humanitarian information to the map, the sudden shift toward information that could aid international military intervention was unmistakable. How useful was this information, though? Agencies in the U.S. Intelligence Community convert raw data into useable information (incorporated into finished intelligence) by utilising some form of the Intelligence Process. As outlined in the U.S. military’s joint intelligence manual, this consists of six interrelated steps all centred on a specific mission. It is interesting that many Twitter users, though perhaps unaware of the intelligence process, replicated each step during the Libyan civil war; producing finished intelligence adequate for consumption by NATO commanders and rebel leadership. It…

Papers on Policy, Activism, Government and Representation: New Issue of Policy and Internet

by David Sutcliffe 16/01/2013

Investigating the relationship between Internet-based applications and data and the policy process.

by David Sutcliffe 16/01/2013

We are pleased to present the combined third and fourth issue of Volume 4 of Policy and Internet. It contains eleven articles, each of which investigates the relationship between Internet-based applications and data and the policy process. The papers have been grouped into the broad themes of policy, government, representation, and activism. POLICY: In December 2011, the European Parliament Directive on Combating the Sexual Abuse, Sexual Exploitation of Children and Child Pornography was adopted. The directive’s much-debated Article 25 requires Member States to ensure the prompt removal of child pornography websites hosted in their territory and to endeavor to obtain the removal of such websites hosted outside their territory. Member States are also given the option to block access to such websites to users within their territory. Both these policy choices have been highly controversial and much debated; Karel Demeyer, Eva Lievens, and Jos Dumortie analyse the technical and legal means of blocking and removing illegal child sexual content from the Internet, clarifying the advantages and drawbacks of the various policy options. Another issue of jurisdiction surrounds government use of cloud services. While cloud services promise to render government service delivery more effective and efficient, they are also potentially stateless, triggering government concern over data sovereignty. Kristina Irion explores these issues, tracing the evolution of individual national strategies and international policy on data sovereignty. She concludes that data sovereignty presents national governments with a legal risk that can’t be addressed through technology or contractual arrangements alone, and recommends that governments retain sovereignty over their information. While the Internet allows unprecedented freedom of expression, it also facilitates anonymity and facelessness, increasing the possibility of damage caused by harmful online behaviour, including online bullying. Myoung-Jin Lee, Yu Jung Choi, and Setbyol Choi investigate the discourse surrounding the introduction of the Korean Government’s “Verification of Identity” policy, which aimed to foster a more responsible Internet culture by mandating registration of a user’s real…
