In the last few years, electronic media brought a revolution in the traceability of social phenomena. As particles in a bubble chamber, social trajectories leave digital trails that can be analyzed to gain a deeper understanding of collective life. To make sense of these traces a renewed collaboration between social and natural scientists is needed...

Controversy mapping is a teaching and research method derived from the Science and Technology Studies and meant to explore and represent modern sociotechnical issues. Striving to make the intricacy of scientific debate readable for a larger public, controversy mapping is trapped in a classic simplicity/complexity trade-­‐off: how to respect the ric...

This article proposes an original analysis of the international debate on climate change through the use of digital methods. Its originality is twofold. First, it examines a corpus of reports covering 18 years of international climate negotiations, a dataset never explored before through digital techniques. This corpus is particularly interesting b...

This work aims at emphasizing a number of questions that, although crucial since the early days of media studies, have not yet been the object of the empirical and computational study that they deserve: How does collective attention concentrate and dissipate in modern communication systems? How do subjects and sources rise and fall in public debate...

In this paper, we investigate the process of scientific discovery using an under-exploited source of information: the Polymath projects. Polymath projects are an original attempt to solve a series mathematical problems collectively and in a collaborative online environment. To investigate the Polymath experiment, we analyze all the posts related to...

In this paper, we investigate the relational architecture of the Intergovernmental Panel on Climate Change (IPCC) focussing on the individuals that, in the thirty years of its existence, have assured the connection between its different components. To study relational bridging within the IPCC, we created a unique database of all the individuals who...

We propose a novel framework for predicting the factuality of reporting of news media outlets by studying the user attention cycles in their YouTube channels. In particular, we design a rich set of features derived from the temporal evolution of the number of views, likes, dislikes, and comments for a video, which we then aggregate to the channel l...

This article shows how a machine can employ a network view to reason about complex social relations of news reliability. Such a network view promises a topic-agnostic perspective that can be a useful hint on reliability trends and their heterogeneous assumptions. In our analysis, we depart from the ever-growing numbers of papers trying to find mach...

In this work we dig into the process of scientific discovery by looking at a yet unexploited source of information: Polymath projects. Polymath projects are an original attempt to collectively solve mathematical problems in an online collaborative environment. To investigate the Polymath experiment, we analyze all the posts related to the projects...
Article

In this article, we present a type of media disorder which we call ‘junk news bubbles’ and which derives from the effort invested by online platforms and their users to identify and circulate contents with rising popularity. Such emphasis on trending matters, we claim, can have two detrimental effects on public debates: first, it shortens the amoun...
Article
Full-text available
It is increasingly common in natural and social sciences to rely on network visualizations to explore relational datasets and illustrate findings. Such practices have been around long enough to prove that scholars find it useful to project networks in a two-dimensional space and to use their visual qualities as proxies for their topological feature...

Article
Full-text available
In this article, we examine how the social disturbance precipitated by ‘fake news’ can be viewed as a kind of infrastructural uncanny. We suggest that the threat of problematic and viral junk news can raise existential questions about the routine circulation, engagement and monetisation of content through the Web and social media. Prompted by the u...

This article contributes to the study of climate debates online by examining how the IPCC Special Report on Global Warming of 1.5°C (SR15) played out on YouTube following its release in October 2018. We examined features of 40 videos that ranked the highest in YouTube's search engine over the course of four weeks after the publication of the report...

It is an increasingly common practice in several natural and social sciences to rely on network visualisations both as heuristic tools to get a first overview of relational datasets and as a way to offer an illustration of network analysis findings. Such practice has been around long enough to prove that scholars find it useful to project networks...

API-based research is an approach to computational social sciences and digital sociology based on the extraction of records from the datasets made available by online platforms through their application programming interfaces (or APIs). This type of research has allowed the collection of detailed information on large populations, thereby effectivel...

In this paper, we discuss the role of Mathematics in articulating reality in theoretical Physics. We propose a parallel between empirical and theoretical work and investigate how scientists can also speak about reality without performing any laboratory trial, a key explanation element of STS. To do so, we examine Einsteins 1905 paper on the nature...

Networks are classic but under-acknowledged figures of journalistic storytelling. Who is connected to whom and by which means? Which organizations receive support from which others? What resources or information circulate through which channels and which intermediaries enable and regulate their flows? These are all customary stories and lines of in...

Digital Methods can be defined as the repurposing of the inscriptions generated by digital media for the study of collective phenomena. The strength of these methods comes from their capacity to take advantage of the data and computational capacities of online platforms; their weakness comes from the difficulty to separate the phenomena that they i...

In this article, we discuss Facebook’s strategy to influence the development of a new communication format known as live video streaming. We take this case study as an example of the ways in which Web platforms operate to harness media innovations and their social uses. The case of Facebook Live illustrates exemplary how, far from developing sponta...

A change of speed In the BBC documentary The Blue Planet, the British naturalist David Attenborough narrates marine life commenting on the 'time-lapsed' images of a tropical reef. The images are beautiful and surprising. Played at accelerated speed, the sequences reveal corals for what they actually are: not minerals or plants, but animals who grow...

In this article, we present a few lessons we learnt in the establishment of the Sciences Po médialab. As an interdisciplinary laboratory associating social scientists, code developers and information designers, the médialab is not one of a kind. In the last years, several of such initiatives have been established around the world to harness the pot...

The description of large temporal graphs requires effective methods giving an appropriate mesoscopic partition. Many approaches exist today to detect communities in static graphs. However, many networks are intrinsically dynamical, and need a dynamic mesoscale description, as interpreting them as static networks would cause loss of important inform...

No doubt, networks have become indispensable mathematical tools in many aspects oflife in the twenty first century. They allow us to calculate all kinds of relational metricsand to quantify the properties of their nodes, clusters and global structures. Thesemodes of calculation are becoming increasingly prevalent in an age of digital data. Butnetwo...

The web is a field of investigation for social sciences, and platform-based studies have long proven their relevance. However the generic web is rarely studied in itself though it contains crucial aspects of the embodiment of social actors: personal blogs, institutional websites, hobby-specific media… We realized that some sociologists see existing...

This paper is about the politics of transdisciplinarity. Not in the sense of the research politics fostering collaboration across disciplines, but in the stronger sense of transcending disciplinary boundaries to make significant political contributions. In short: it is about the making research public. Also, this chapter is not theoretical: it disc...
