More than complex: large and rich network structures

I co-organize this Satellite to the NETSCI2018 Conference in Paris, 12 June 2018. We are now accepting submissions of proposals for presentations.

Information on the Satellite

In traditional research paradigms, sociology handles small but rich networks where the richness of network attributes is derived from the specific buildup of the data collection process. In the sociological approach, differences among nodes and edges are key to describe network properties and the ensuing dynamical social processes. Instead, the complex systems tradition deals with large but poor networks. Assuming statistical equivalence of graph entities, a mean field treatment serves to describe the aggregate properties of the network. Today’s network datasets contain an unprecedented quantity of relational information at all, and between all, the possible levels: individuals, social groups, political structures, economical actors, etc. We finally deal with large and rich network structures that expose the implicit limitations of the two abovementioned approaches: the traditional methods from social science cannot be upscaled because of their algorithmic complexity and those from complex systems lose track of the complex nature of the actors, their relationships and their processes. This workshop has the aim of developing an interdisciplinary reflection on how methods from social science could be upscaled to large network structures and on how methods from complex systems could be downscaled to deal with small heterogeneous structures.

We are proud that five prominent international scholars are our invited speakers: Camille Roth, SciencesPo Paris; Matthieu Latapy, LIP6UPMC Paris; Alessandro Lomi, ETH Zurich; Fariba Karimi, GESIS Cologne; Noshir Contractor, Northwestern University.

Contributions

We invite abstracts of published or unpublished work for contributed talks to take place at the satellite symposium. We expect a broad range of topics to be covered, across theory, methodology, and application to empirical data, relating to an interdisciplinary reflection on how methods from social science could be upscaled to large network structures and on how methods from complex systems could be downscaled to deal with small heterogeneous structures.

Submission can be made through our website.

Submissions are required to be at most 650 words long and should include the following information: title of the talk, author(s), affiliation(s), email address(es), name of the presenter, abstract. Papers or submissions longer than 1 page will not be accepted.

Important dates

Abstract submission deadline is March 25, 2018. Notification of acceptance will be no later than April 23, 2018.

All participants and accepted speakers will have to register through the NETSCI2018 website.

Sharing Networks BCN 2017

Did you attend the OuiShare Fest Barcelona 2017? If you did, and were not interviewed by a member of our team there, please take our survey online!

With a group of colleagues from Universitat Autònoma de Barcelona and in Collaboration with OuiShare, we are studying networking at the event. The OuiShare Fest aims, among other things, to bring people together: we want to see how interactions between participants facilitate circulation of ideas and possibly give rise to future collaborations.

We did the same study at the OuiShare Fest Paris 2016 and 2017.

SPS seminar, second edition

Our inter-disciplinary, inter-institutional SPS seminar (Paris Seminar on the Analysis of Social Processes and Structures) has just started its second edition! Its purpose is to take stock of the debates within the international scientific community that have repercussions on the practice of contemporary sociology, and that renew the ways in which we construct research designs, i.e., the ways in which we connect theoretical claims, data collection and methods to assess the link between data and theory. Several observations motivate this endeavor. Increasing interactions between social sciences and disciplines such as computer science, physics and biology outline new conceptual and methodological perspectives on social realities. The availability of massive data sets raises the question of the tools required to describe, visualize and model these data sets. Simulation techniques, experimental methods and counterfactual analyses modify our conceptions of causality. Crossing sociology’s disciplinary frontiers, network analysis expands its range of scales. In addition, the development of mixed methods redraws the distinction between qualitative and quantitative approaches. In light of these challenges, the SPS seminar discusses studies that, irrespective of their subject and disciplinary background, provide the opportunity to deepen our understanding of the relations between theory, data and methods in social sciences.

Recent ethical challenges in social network analysis (RECSNA17)

Research on social networks is experiencing unprecedented growth, fuelled by the consolidation of network science and the increasing availability of data from digital networking platforms. However, it raises formidable ethical issues that often fall outside existing regulations and guidelines. New tools to collect, treat, store personal data expose both researchers and participants to specific risks. Political use and business capture of scientific results transcend standard research concerns. Legal and social ramifications of studies on personal ties and human networks surface.

We invite contributions from researchers in the social sciences, economics, management, statistics, computer science, law and philosophy, as well as other stakeholders to advance the ethical reflection in the face of new research challenges.

The workshop will take place on 5 December 2017 (full day) at MSH Paris-Saclay, with open keynote sessions to be held on 6 December 2017 (morning) at Hôtel de Lauzun, a 17th century palace in the heart of historic Île de la Cité.

Calendar:

  • Submit a 300-word abstract by 15 October 2017.
  • Let us know if you wish to be panel discussant or session chair by 20 October 2017 (send to: recsna17@msh-paris-saclay.fr).
  • Acceptance notifications will be sent by 31 October 2017.
  • Registration is free but mandatory: speakers (and discussants and chairs) should register between 15 October and 15 November 2017, other attendees by 30 November 2017.

Keynote Speakers

José Luis Molina, Autonomous University of Barcelona, “HyperEthics: A Critical Account”
Bernie Hogan, Oxford Internet Institute, “Privatising the personal network: Ethical challenges for social network site research”

Sharing Networks 2017: pen-and-paper fieldwork in a big data world

I’m excited to report that earlier this month, I ran the second wave of data collection for our Sharing Networks research project at OuiShare Fest 2017!

Publicizing the survey at OuiShare Fest 2017

To understand how people form and reinforce face-to-face network ties at such an event, I fielded a questionnaire with the help of a committed and effective team of co-researchers. It is a “name generator” asking respondents to name those they knew before the OuiShare Fest, and met again  there (“old frields”); and those they met during the event for the first time (“new contacts”). Participants then have to choose those among their “old” and “new” contacts, that they would like to contact again in future for joint projects or collaborations.

Interestingly, my good old pen-and-paper questionnaire still gives a lot of insight that digital data from social media cannot provide – just like a highly computer literate community such as this feels the need to meet physically in one place every year for a few days. Like trade fairs that flourish even more in the internet era, the OuiShare Fest gathers more participants at each edition. They meet in person there, which is why they are to be invited to respond in person too.

Sharing Networks study 2017: Moving online!

I’m so excited that earlier this month, I ran the second wave of data collection for my Sharing Networks research project at OuiShare Fest 2017!

The Sharing Networks 2017 survey team (incomplete).

The study aims to map the collaborative economy community that gathers at OuiShare Fest, looking at how people network and how this fosters the emergence of new trends and topics.

During the event, a small team of committed and effective co-researchers helped me interview participants. We used a questionnaire with a “name generator” format, typically used in social network analysis to elicit people’s connections and reconstitute their social environment.

Specifically, we asked respondents to name people they knew before the

OuiShare Fest, and met again there (“old friends”), and people they met during the Fest for the first time (“new contacts”). Then we asked them to choose, from among the “old” and “new” they had named, those they would like to contact again with soon, for example for joint projects or collaborations.

I am very happy with the result: 160 completed interviews over three half-days! But it is still not enough: participants to the Fest were much more numerous than that, and in social network analysis, it is well-known that sampling is insufficient, and one needs to get as close to exhaustiveness as possible.

Therefore, for those OuiShare Fest 2017 participants that we did not manage to interview, there is now an opportunity to complete the questionnaire online.

If you were at the Fest and we did not talk to you, please do participate now! It takes less than 8 minutes, and you will help the research team as well as the organization of the Fest.

Many thanks to the team of co-researchers who helped me, the OuiShare team members who supported us, and all respondents.
