Emerging Technology From the arXiv: “Nobody agrees on how to define a city. But the emergence of “natural cities” from social media data sets may change that, say computational geographers…
A city is a large, permanent human settlement. But try and define it more carefully and you’ll soon run into trouble. A settlement that qualifies as a city in Sweden may not qualify in China, for example. And the reasons why one settlement is classified as a town while another as a city can sometimes seem almost arbitrary.
City planners know this problem well. They tend to define cities by administrative, legal or even historical boundaries that have little logic to them. Indeed, the same city can sometimes be defined in various different ways.
That causes all kinds of problems from counting the total population to working out who pays for the upkeep of the place. Which definition do you use?
Now help may be at hand thanks to the work of Bin Jiang and Yufan Miao at the University of Gävle in Sweden. These guys have found a way to use people’s location recorded by social media to define the boundaries of so-called natural cities which have a close resemblance to real cities in the US.
Jiang and Miao began with a dataset from the Brightkite social network, which was active between 2008 and 2010. The site encouraged users to log in with their location details so that they could see other users nearby. So the dataset consists of almost 3 million locations in the US and the dates on which they were logged.
To start off, Jiang and Miao simply placed a dot on a map at the location of each login. They then connected these dots to their neighbours to form triangles that end up covering the entire mainland US.
Next, they calculated the size of each triangle on the map and plotted this size distribution, which turns out to follow a power law. So there are lots of tiny triangles but only a few large ones.
Finally, the calculated the average size of the triangles and then coloured in all those that were smaller than average. The coloured areas are “natural cities”, say Jiang and Miao.
It’s easy to imagine that resulting map of triangles is of little value. But to the evident surprise of ther esearchers, it produces a pretty good approximation of the cities in the US. “We know little about why the procedure works so well but the resulting patterns suggest that the natural cities effectively capture the evolution of real cities,” they say.
That’s handy because it suddenly gives city planners a way to study and compare cities on a level playing field. It allows them to see how cities evolve and change over time too. And it gives them a way to analyse how cities in different parts of the world differ.
Of course, Jiang and Miao will want to find out why this approach reveals city structures in this way. That’s still something of a puzzle but the answer itself may provide an important insight into the nature of cities (or at least into the nature of this dataset).
A few days ago, this blog wrote about how a new science of cities is emerging from the analysis of big data. This is another example and expect to see more.

Shedding Light on Projects Through Contract Transparency
OpenAidMap: “In all countries, whether rich or poor, contracts are at the nexus of revenue generation, budget planning, resource management and the delivery of public goods. Open contracting refers to norms and practices for increased disclosure and participation in public contracting at all stages of the contracting process.
There are very good reasons for making procurement processes transparent. Public posting of tender notices and “requests for proposals” helps support free and fair competitive bidding – increasing citizen trust while also improving the likelihood of securing the best possible supplier. Once procurement is finished, public posting of contract awards gives important assurance for citizens, development partners, and competing companies that procurement processes are open and fair. Increasingly, open contracting in procurement transparency through portals like this one is becoming the norm for governments around the world. There is also a global initiative at work to establish a common standard for contracting data….
With so much momentum behind procurement transparency, there is an untapped opportunity to leverage data from public procurement processes to provide operational insight into activities. Procurement data can help answer two of the most important questions in project-level aid transparency: (1) Where are projects taking place? (2) How much money is being invested at each location?
Take an example from Nepal. Consulting the government’s aid management system yields some basic, but already useful, information about a particular transportation project. This type of information can be useful for anyone trying to assess patterns of transportation investment in the country or, for that matter, patterns of development partner financing….
Open contracting data have intrinsic value for transparency and accountability. However, they also have significant value for planners – even those who only care about getting greater insight into project activities. At the moment though, contracting data are too difficult to access. While contracting data are increasingly becoming available, they are often posted on stand-alone websites, in diverse data formats and without structured access. By standardizing around a core contracting data format and accessibility approach, we can unlock the potential to use contracting data at scale not only for transparency, but also as an effort-free addition to the arsenal of available data for project-level planning, coordination, and accountability. The utility could be even higher if combined with performance and results data.
When developing any public data standard, there are opportunities and risks. For open contracting data, there is a huge opportunity to make those data equally relevant for project planners as for those more purely interested in transparency and accountability. The pilot conducted by the Open Aid Partnership and AidData has explored this potential for overlap, yielding key insights that we hope can be used in the future development of an open and broadly relevant open contracting data standard.”
The Age of ‘Infopolitics’
Colin Koopman in the New York Times: “We are in the midst of a flood of alarming revelations about information sweeps conducted by government agencies and private corporations concerning the activities and habits of ordinary Americans. After the initial alarm that accompanies every leak and news report, many of us retreat to the status quo, quieting ourselves with the thought that these new surveillance strategies are not all that sinister, especially if, as we like to say, we have nothing to hide.
One reason for our complacency is that we lack the intellectual framework to grasp the new kinds of political injustices characteristic of today’s information society. Everyone understands what is wrong with a government’s depriving its citizens of freedom of assembly or liberty of conscience. Everyone (or most everyone) understands the injustice of government-sanctioned racial profiling or policies that produce economic inequality along color lines. But though nearly all of us have a vague sense that something is wrong with the new regimes of data surveillance, it is difficult for us to specify exactly what is happening and why it raises serious concern, let alone what we might do about it.
Our confusion is a sign that we need a new way of thinking about our informational milieu. What we need is a concept of infopolitics that would help us understand the increasingly dense ties between politics and information. Infopolitics encompasses not only traditional state surveillance and data surveillance, but also “data analytics” (the techniques that enable marketers at companies like Target to detect, for instance, if you are pregnant), digital rights movements (promoted by organizations like the Electronic Frontier Foundation), online-only crypto-currencies (like Bitcoin or Litecoin), algorithmic finance (like automated micro-trading) and digital property disputes (from peer-to-peer file sharing to property claims in the virtual world of Second Life). These are only the tip of an enormous iceberg that is drifting we know not where.
Surveying this iceberg is crucial because atop it sits a new kind of person: the informational person. Politically and culturally, we are increasingly defined through an array of information architectures: highly designed environments of data, like our social media profiles, into which we often have to squeeze ourselves. The same is true of identity documents like your passport and individualizing dossiers like your college transcripts. Such architectures capture, code, sort, fasten and analyze a dizzying number of details about us. Our minds are represented by psychological evaluations, education records, credit scores. Our bodies are characterized via medical dossiers, fitness and nutrition tracking regimens, airport security apparatuses. We have become what the privacy theorist Daniel Solove calls “digital persons.” As such we are subject to infopolitics (or what the philosopher Grégoire Chamayou calls “datapower,” the political theorist Davide Panagia “datapolitik” and the pioneering thinker Donna Haraway “informatics of domination”).
Today’s informational person is the culmination of developments stretching back to the late 19th century. It was in those decades that a number of early technologies of informational identity were first assembled. Fingerprinting was implemented in colonial India, then imported to Britain, then exported worldwide. Anthropometry — the measurement of persons to produce identifying records — was developed in France in order to identify recidivists. The registration of births, which has since become profoundly important for initiating identification claims, became standardized in many countries, with Massachusetts pioneering the way in the United States before a census initiative in 1900 led to national standardization. In the same era, bureaucrats visiting rural districts complained that they could not identify individuals whose names changed from context to context, which led to initiatives to universalize standard names. Once fingerprints, biometrics, birth certificates and standardized names were operational, it became possible to implement an international passport system, a social security number and all other manner of paperwork that tells us who someone is. When all that paper ultimately went digital, the reams of data about us became radically more assessable and subject to manipulation, which has made us even more informational.
We like to think of ourselves as somehow apart from all this information. We are real — the information is merely about us. But what is it that is real? What would be left of you if someone took away all your numbers, cards, accounts, dossiers and other informational prostheses? Information is not just about you — it also constitutes who you are….”
Google Hangouts vs Twitter Q&As: how the US and Europe are hacking traditional diplomacy
Wired (UK): “We’re not yet sure if diplomacy is going digital or just the conversations we’re having,” Moira Whelan, Deputy Assistant Secretary for Digital Strategy, US Department of State, admitted on stage at TedxStockholm. “Sometimes you just have to dive in, and we’re going to, but we’re not really sure where we’re going.”
The US has been at the forefront of digital diplomacy for many years now. President Obama was the first leader to sign up to Twitter, and has amassed the greatest number of followers among his peers at nearly 41 million. The account is, however, mainly run by his staff. It’s understandable, but demonstrates that there still remains a diplomatic disconnect in a country Whelan says knows it’s “ready, leading the conversation and on cutting edge”.
In Europe Swedish Minister for Foreign Affairs Carl Bildt, on the other hand, carries out regular Q&As on the social network and is regarded as one of the most conversational leaders on Twitter and the best connected, according to annual survey Twiplomacy. Our own William Hague is chasing Bildt with close to 200,000 followers, and is the world’s second most connected Foreign Minister, while David Cameron is active on a daily basis with more than 570,000 followers. London was in fact the first place to host a “Diplohack”, an event where ambassadors are brought together with developers and others to hack traditional diplomacy, and Whelan travelled to Sweden to take place in the third European event, the Stockholm Initiative for Digital Diplomacy held 16-17 January in conjunction with TedxStockholm.
Nevertheless, Whelan, who has worked for the state for a decade, says the US is in the game and ready to try new things. Case in point being its digital diplomacy reaction to the crisis in Syria last year.
“In August 2013 we witnessed tragic events in Syria, and obviously the President of the United States and his security team jumped into action,” said Whelan. “We needed to bear witness and… very clearly saw the need for one thing — a Google+ Hangout.” With her tongue-in-cheek comment, Whelan was pointing out social media’s incredibly relevant role in communicating to the public what’s going on when crises hit, and in answering concerns and questions through it.
“We saw speeches and very disturbing images coming at us,” continued Whelan. “We heard leaders making impassioned speeches, and we ourselves had conversations about what we were seeing and how we needed to engage and inform; to give people the chance to engage and ask questions of us.
“We thought, clearly let’s have a Google+ Hangout. Three people joined us and Secretary John Kerry — Nicholas Kirstof of the New York Times, executive editor of Syria Deeply, Lara Setrakian and Andrew Beiter, a teacher affiliated with the Holocaust Memorial Museum who specialises in how we talk about these topics with our children.”
In the run up to the Hangout, news of the event trickled out and soon Google was calling, asking if it could advertise the session at the bottom of other Hangouts, then on YouTube ads. “Suddenly 15,000 people were watching the Secretary live — that’s by far largest number we’d seen. We felt we’d tapped into something, we knew we’d hit success at what was a challenging time. We were engaging the public and could join with them to communicate a set of questions. People want to ask questions and get very direct answers, and we know it’s a success. We’ve talked to Google about how we can replicate that. We want to transform what we’re doing to make that the norm.”
Secretary of State John Kerry is, Whelan told Wired.co.uk later, “game for anything” when it comes to social media — and having the department leader enthused at the prospect of taking digital diplomacy forward is obviously key to its success.
“He wanted us to get on Instagram and the unselfie meme during the Philippines crisis was his idea — an assistant had seen it and he held a paper in front of him with the URL to donate funds to Typhoon Haiyan victims,” Whelan told Wired.co.uk at the Stockholm diplohack. “President Obama came in with a mandate that social media would be present and pronounced in all our departments.”
“[As] government changes and is more influenced away from old paper models and newspapers, suspenders and bow ties, and more into young innovators wanting to come in and change things,” Whelan continued, “I think it will change the way we work and help us get smarter.”
Use big data and crowdsourcing to detect nuclear proliferation, says DSB
FierceGovernmentIT: “A changing set of counter-nuclear proliferation problems requires a paradigm shift in monitoring that should include big data analytics and crowdsourcing, says a report from the Defense Science Board.
Much has changed since the Cold War when it comes to ensuring that nuclear weapons are subject to international controls, meaning that monitoring in support of treaties covering declared capabilities should be only one part of overall U.S. monitoring efforts, says the board in a January report (.pdf).
There are challenges related to covert operations, such as testing calibrated to fall below detection thresholds, and non-traditional technologies that present ambiguous threat signatures. Knowledge about how to make nuclear weapons is widespread and in the hands of actors who will give the United States or its allies limited or no access….
The report recommends using a slew of technologies including radiation sensors, but also exploitation of digital sources of information.
“Data gathered from the cyber domain establishes a rich and exploitable source for determining activities of individuals, groups and organizations needed to participate in either the procurement or development of a nuclear device,” it says.
Big data analytics could be used to take advantage of the proliferation of potential data sources including commercial satellite imaging, social media and other online sources.
The report notes that the proliferation of readily available commercial satellite imagery has created concerns about the introduction of more noise than genuine signal. “On balance, however, it is the judgment from the task force that more information from remote sensing systems, both commercial and dedicated national assets, is better than less information,” it says.
In fact, the ready availability of commercial imagery should be an impetus of governmental ability to find weak signals “even within the most cluttered and noisy environments.”
Crowdsourcing also holds potential, although the report again notes that nuclear proliferation analysis by non-governmental entities “will constrain the ability of the United States to keep its options open in dealing with potential violations.” The distinction between gathering information and making political judgments “will erode.”
An effort by Georgetown University students (reported in the Washington Post in 2011) to use open source data analyzing the network of tunnels used in China to hide its missile and nuclear arsenal provides a proof-of-concept on how crowdsourcing can be used to augment limited analytical capacity, the report says – despite debate on the students’ work, which concluded that China’s arsenal could be many times larger than conventionally accepted…

Prospects for Online Crowdsourcing of Social Science Research Tasks: A Case Study Using Amazon Mechanical Turk
New paper by Catherine E. Schmitt-Sands and Richard J. Smith: “While the internet has created new opportunities for research, managing the increased complexity of relationships and knowledge also creates challenges. Amazon.com has a Mechanical Turk service that allows people to crowdsource simple tasks for a nominal fee. The online workers may be anywhere in North America or India and range in ability. Social science researchers are only beginning to use this service. While researchers have used crowdsourcing to find research subjects or classify texts, we used Mechanical Turk to conduct a policy scan of local government websites. This article describes the process used to train and ensure quality of the policy scan. It also examines choices in the context of research ethics.”
Supporting open government in New Europe
Google Europe Blog: “The “New Europe” countries that joined the European Union over the past decade are moving ahead fast to use the Internet to improve transparency and open government. We recently partnered with Techsoup Global to support online projects driving forward good governance in Romania, the Czech Republic, and most recently, in Slovakia.

- Demagog.sk – a platform focused on analyzing public statements of politicians and releasing information about politicians and truthfulness of their speeches in a user-friendly format.”
From Faith-Based to Evidence-Based: The Open Data 500 and Understanding How Open Data Helps the American Economy
Beth Noveck in Forbes: “Public funds have, after all, paid for their collection, and the law says that federal government data are not protected by copyright. By the end of 2009, the US and the UK had the only two open data one-stop websites where agencies could post and citizens could find open data. Now there are over 300 such portals for government data around the world with over 1 million available datasets. This kind of Open Data — including weather, safety and public health information as well as information about government spending — can serve the country by increasing government efficiency, shedding light on regulated industries, and driving innovation and job creation.
It’s becoming clear that open data has the potential to improve people’s lives. With huge advances in data science, we can take this data and turn it into tools that help people choose a safer hospital, pick a better place to live, improve the performance of their farm or business by having better climate models, and know more about the companies with whom they are doing business. Done right, people can even contribute data back, giving everyone a better understanding, for example of nuclear contamination in post-Fukushima Japan or incidences of price gouging in America’s inner cities.
The promise of open data is limitless. (see the GovLab index for stats on open data) But it’s important to back up our faith with real evidence of what works. Last September the GovLab began the Open Data 500 project, funded by the John S. and James L. Knight Foundation, to study the economic value of government Open Data extensively and rigorously. A recent McKinsey study pegged the annual global value of Open Data (including free data from sources other than government), at $3 trillion a year or more. We’re digging in and talking to those companies that use Open Data as a key part of their business model. We want to understand whether and how open data is contributing to the creation of new jobs, the development of scientific and other innovations, and adding to the economy. We also want to know what government can do better to help industries that want high quality, reliable, up-to-date information that government can supply. Of those 1 million datasets, for example, 96% are not updated on a regular basis.
The GovLab just published an initial working list of 500 American companies that we believe to be using open government data extensively. We’ve also posted in-depth profiles of 50 of them — a sample of the kind of information that will be available when the first annual Open Data 500 study is published in early 2014. We are also starting a similar study for the UK and Europe.
Even at this early stage, we are learning that Open Data is a valuable resource. As my colleague Joel Gurin, author of Open Data Now: the Secret to Hot Start-Ups, Smart Investing, Savvy Marketing and Fast Innovation, who directs the project, put it, “Open Data is a versatile and powerful economic driver in the U.S. for new and existing businesses around the country, in a variety of ways, and across many sectors. The diversity of these companies in the kinds of data they use, the way they use it, their locations, and their business models is one of the most striking things about our findings so far.” Companies are paradoxically building value-added businesses on top of public data that anyone can access for free….”

Protecting personal data in E-government: A cross-country study
Paper by Yuehua Wu in Government Information Quarterly: “This paper presents the findings of a comparative study of laws and policies employed to protect personal data processed in the context of e-government in three countries (the United States, Germany, and China) with rather different approaches. Drawing on governance theory, the paper seeks to document the mechanisms utilized and to understand the factors that shape the governance modes adopted. The cases reveal that national government regulations have not kept pace with technological change and with the current information practices of the public sector. Nonetheless, traditional government regulation remains the major governance mode for the issue under discussion. Self-regulation and code-based regulation serve supplementary roles to traditional government regulation. National context is found to impact the form and level of data protection and the choice of governance modes.”
