Open Data: What’s new in 2017?

I am now in Montréal, where I participated, last Friday, in a panel on Open Data at “Science & You” international conference. It was interesting for me to reflect on how the picture has changed since my previous panel on the same topic – in Kiev in 2012. Back then, we were busy trying to convince public administrations that data opening was good for transparency and could help improve services to communities. Since then, a lot of attempts have been made in numerous countries – local authorities often pioneering the process, followed only later by central governments (one example cited in my panel was Québec City). What is made open is typically information from public registers (first names of newborns, records of road accidents) and increasingly, from technological devices and sensors (bus traffic information).

There are some conditions to be met for a dataset to be said “open”:

  • Technically, it needs to be “raw”, detailed, digital and reusable. The French Interior Ministry released results of the first round of the recent presidential elections within a few days, at polling station level. This is sufficiently detailed (with over 69,000 polling stations throughout the country), raw (allowing aggregations, comparisons etc.), and digital/reusable (so much so that the newspaper Le Monde could develop a user-friendly application to let readers easily check results in their neighborhoods). Some would also insist that “open” data should be released in non-proprietary formats (better .csv than .xls, for example).
  • Legally, the data must come with a license that allows re-use by third parties (typically within the Creative Commons family). Ideally, no type of reuse should be ruled out (including somewhat controversially, commercial / for-profit reuse).
  • Economically, the data should be available to all for free (or at least with minimal charges if data preparation requires extra work or expenses).

If in the past few years, a lot of thought has been devoted to the “ideal” conditions for data opening and how this would positively affect public service, the data landscape has now significantly changed.

Are we all data laborers?

autonomyI gave today a talk at AUTONOMY, a major festival of urban mobility in Paris, where new technologies are at center stage, from driverless cars to electric scooters, bike-sharing solutions, and connected infrastructure for the smart city. I had been asked to talk about labor in digital platforms, such as those offering mobility services.

Digital platforms are often thought of in terms of automation, but it islogos clear that there is labor too: we all have in mind the example of the couriers and drivers of the “on-demand” economy. But there’s more: I’ll show how platforms involve the labor of everyone, including passengers and users of all types. By labor, I mean here human activity that produces data and information – the key source of value for platforms. It is often an implicit, invisible activity of which we may not even be aware – as we tend to focus more on consumption aspects as we talk routinely about “car pooling” or “car sharing”, rather than looking at the underlying productive effort. This is what scholars call “digital labor”.

Four eco-systems

Specialist Antonio Casilli distinguishes four forms of digital labor in platforms, and I am now going to briefly outline them.

Ethical issues in research with online data

Some time ago, I wrote a post on ethical issues in research with secondary data – a somewhat grey area, where students and scholars often feel guidance is insufficient. Even more complex is research with internet data – neither primary nor secondary strictly speaking, but “big” data. A recent case fuelled an international debate on how researchers should deal with data that are, apparently, accessible to all on the web: a Danish graduate student published a large dataset of users of the online dating site OkCupid (he apparently did so without any institutional backing, and Aarhus University where he studies, is now on the case). Michael Zimmer, a specialist of information studies and the policy and ethics of online research, properly summarizes the issues in a recent Wired article:

  • Don’t say that “the data are already public”. The fact that OkCupid users knowingly share some personal information, does not mean they consent to it being used for purposes other than interactions with other users on that site. By scrapping data, one may be able to put together the whole history of  users’ presence on that platform, revealing more of their life or personality than they themselves are aware of. More dangerously, data extracted in this way might in some cases be matched with other information, thereby potentially becoming much more disclosive than what the persons concerned ever intended or agreed. And the disclosure may be aggravated by releasing the data outside the platform.

“Data for Humanity”: a simple message, but so necessary

The recent VW emissions scandal says it all: even a large company can’t get away with behaviours that disrespect key societal values. Protection of the  environment is among these values today, so much so that not only public authorities step in to defend it, but even markets punish the transgressors.

Data protection is not (yet) such a value. Admittedly, some associations, individuals, and government officials fight for it, but the larger public is still unsure. It’s not that people don’t care, but that uncertainty as to what data are actually collected, for what usages, and by whom, is overwhelming; and it becomes difficult to identify the best course of action.

In this context, a new initiative is most welcome: an open letter on “Data for Humanity“, initiated by two scholars of the University of Frankfurt, pleads for a more responsible use of data. The message is simple: Do no harm. And if you can, on top of it, do something good. It’s so simple, and so necessary.

Sure, the world won’t change after this letter, but it will be a first step. Even the promotion of environmental protection started with simple, basic declarations, 30-40 years ago; and it was by insisting and perseverating, that it finally gained the conscience of everybody.

Data and social networks: empowerment and new uncertainties (in Italian)

I gave a presentation on the topic of “Data and social networks: empowerment and new uncertainties” at the Better Decisions Forum on Big Data and Open Data that took place in Rome on 12 November 2014. The event brought together six speakers from different backgrounds on a variety of topics related to data, and participants were businesspeople, public administration managers, journalists, data and computer scientists.

Here is a video of my talk:



Unfortunately as you will have noticed, the slides are not always very clearly visible, so it’s better to download them from their original source:

See? I am trying to stick to my 1st-January commitment of blogging more this year…

Sharing medical data for research: Why we should all care

A major health data plan is on the verge of being called off, to never have a chance again. It is supposed to anonymise all the patient records in the National Health Service (NHS) in the UK, linking them together into one single, giant database, and making them available under controlled use conditions to health researchers and (controversially) to commercial companies too. Public outcry has led to the plan being delayed for six months.

Stethoscope on clipboard over blood pressure print out #5 In an article published in The Guardian last week, Ben Goldacre, a medical doctor and high-profile media commentator on science matters, rightly identifies what the point is: in principle, the public accepts release of data for scientific purposes, but resists commercial exploitation. And rightly so: medical knowledge results from the study of several cases, and the higher the availability of cases, the more accurate the results; in the era of big data, it is also clear that aggregation and sharing of a wealth of data such as those held by the NHS is a unique opportunity for medical science to discover ways of saving lives. On the other hand, use of data for any other purposes looks much more opaque, and people understandably feel it might lead to discrimination and potentially negative individual consequences, for example if disclosure of the health history of a person results in higher insurance premiums, or rejection of job applications.
