Interactional and Informational Attention on Twitter

Our paper called “Interactional and Informational Attention on Twitter”, by Agathe Baltzer, Marton Karsai and Camille Roth, just got out in Information 10(8), and is featured on its cover page. This work appraises the distribution of attention at the collective and individual level on Twitter, and both from a social (users) and semantic (topics) viewpoint. We exhibit the existence of socio-semantic attentional constraints and focus effects.

Neurons spike back

This article by Dominique Cardon, Jean-Philippe Cointet and Antoine Mazières retraces the history of artificial intelligence through the lens of the tension between symbolic and connectionist approaches. From a social history of science and technology perspective, it seeks to highlight how researchers, relying on the availability of massive data and the multiplication of computing power have undertaken to reformulate the symbolic AI project by reviving the spirit of adaptive and inductive machines dating back from the era of cybernetics.

Appraising algorithmic biases

“Algorithmic Distortion of Informational Landscapes”, by Camille Roth, has just been published in Intellectica 70(1):97-118 –
This review paper focuses on biases induced by recommendation algorithms. It explores the state of the art along a double dichotomy: first regarding the discrepancy between users’ intentions and actions (1) under some algorithmic influence and (2) without it; second, by distinguishes algorithmic biases on (1) prior information rearrangement and (2) posterior information arrangement.

Welcome to Jérémie Poiroux

Jérémie Poiroux is currently completing his masters in information architecture at the ENS of Lyon. He joined the CSS team at Centre Marc Bloch in February. He will be interning for the next six months towards the completion of his thesis, while participating in the AlgoDiv project, under the supervision of Camille Roth. He focuses on sociological issues raised by the design of recommender algorithms and more specifically will devote part of his time to the representation of filter bubbles on Twitter. More information on his research progress may be found on his medium feed.

Welcome to Antoine Mazières

Antoine Mazières just joined the team in the framework of the Algodiv project. He recently submitted his PhD dissertation in Paris on machine learning algorithms and did several quantitative studies on Google recommandations and on pornography. Within the DH-CSS team at CMB, he aims at studying the various kinds of biases which algorithms may induce in online informational landscapes, especially with respect to the production and use of search engine results.

3-year Doctoral Fellowship on information diversity in online communities

We’re looking for a PhD candidate to work with us around the issue of online information diversity. Here are the details:

Main topics: quantification of informational and social diversity in online communities, the digital public space and online media; understanding and modeling of filter bubbles and of the role of algorithms in shaping online informational landscapes.

Keywords: online communities, social complex systems, information diffusion and filtering, filter bubbles, diversity quantification, socio-semantic networks.

Profile: a strong master’s degree either in computer science, applied mathematics or statistical physics, with skills in modeling, data science and a marked interest for social sciences and interdisciplinarity, or in quantitative social science, with prior knowledge of data/network analysis and ICT sociology.

Application deadline: March 20, 2016, applications may be accepted after this date until the position is filled.

14. Berliner DH-Rundgang: Centre Marc Bloch, Dec 7, 4-5:30pm

The “Digital Humanities / Computational Social Science” jointly organizes a workshop with the ifDHB of the BBAW as part of the so-called cycle “Berliner DH Rundgang“, on Monday, December 7 from 4 till 5:30pm . The aim of this cycle is to present DH-related teams towards the academic community of the region. The program of this event, which is open to all and will take place in the Georg-Simmel room at Centre Marc Bloch, is available here.

Berlin-Brandenburg Workshop on Computational Social Science

A critical mass of scholars interested in computational social science emerged in the Berlin-Brandenburg area over the recent years. The goal of this workshop is essentially to provide a local and rather informal opportunity to get to know neighbors who potentially work on related issues.

About 15 academics from the region will introduce some of their research topics. See the attached program for more details on the specific talks.

Where and when: on Nov 11, 2015, from 9am to 2pm. Georg-Simmel-Raum, Centre Marc Bloch, 3rd Floor, Friedrichstrasse 191, U. Stadtmitte, Berlin.

Detailed program: available here

Qual-Quant Meetings: reloaded

A new season of the “Qual-Quant Meetings”, which aim at stimulating interdisciplinary approaches within Centre Marc Bloch, will start on Monday October 26, from 11:15am till 1pm in Georg-Simmel-Raum (see introductory post for more detail on the aim of these sessions).

The updated program for 2015, featuring related activities including a workshop on “Computational Social Sciences in Berlin-Brandenburg” and a Rundgang “Digital Humanities” co-organized by BBAW, may be downloaded here.

Qual-Quant Meetings

Following a handful of methodological workshops over the past year on social network analysis or scientific blogging, the team will from now on organize on a regular (bi-monthly) basis a series of internal meetings on qual-quant approaches.

The sessions will aim at presenting the recently finished or ongoing work of the team as well as proposing methodological workshops conceived as a training to digital methods (fabrication and curation of databases, text processing, etc.). We hope to enter into a fruitful dialog prone to initiative new qual-quant research questions at the Centre.

The first meeting will take place on Friday February 27th, from 3 to 5pm in Georg-Simmel room, featuring the presentation of a study on German and French blog networks together with the introduction of a text corpus processing platform.

The provisional detailed program may be downloaded from here.

Welcome to Lou Charaudeau

Lou Charaudeau just joined the team in the framework of the Algopol project. He currently works on the definition of political communities within Twitter users, relying in particular on press and media links they exchange. This research builds upon his PhD in biomathematics (Oct 2013) on epidemiology, where he could study the propagation of influenza in French cities, based on commuter dynamics. He should categorize cities depending on their transmission behavior. Within the DH team at CMB, he will extend this work towards informational epidemiology.

MSc. seminar “Digitale Kulturen”

Sessions will be devoted to discussing texts dealing with general issues (including the emergence of virtual realms and related investigation methods) or focusing on specific case studies or contemporary debates (such as the impact of the digital public space on democratic practices and cultural divides).

Lecturers: Camille Roth (coord. and contact), Joyce Bessis, Sébastien Lerique and Telmo Menezes.

The full program (in German) is available here.

Date: usually Wednesdays, 10am-noon, from Apr 16 until Jul 16, 2014.
Location: Humboldt Universität, Raum 3, Universitätsstraße 3b, Berlin-Mitte.

Crossing the boundaries – Digital Humanities today and tomorrow

The third workshop of the Einstein-Zirkel “Digital Humanities in Berlin“, in which the CMB-Digital Humanities team takes part, will take place on Feb 28, 2014 (8:30am-5pm) at the Henry Ford Building of the Freie Universität.

It aims at providing an overview of “digital humanities” projects and teams of the Berlin area. The morning will feature about sixty DH projects and institutions during a “poster madness” session. Kurt Fendt (MIT) will then deliver a keynote speech in the early afternoon, where he will be introducing the Hyperstudio of the MIT and several research projects which are being hosted there. A final podium will gather various key representatives of the local institutions, including Peter-André Alt (FU’s president), Peter Frensch (VP-Research at HU), Jürgen Renn (Director of MPI-WG), Günther Schauerte (VP Stiftung Preußischer Kulturbesitz), Reinhard Förtsch (Scientific Director of DAI-Berlin) and Wolf-Hagen Krauth (Scientific Director of BBAW), to discuss the future of Digital Humanities in Berlin.
