First part of the analysis chose to picture the global conversation on Twitter by picking 3 accounts in Italian, Spanish and English languages.
We identified several clusters gathering professional epidemiologists.
In this follow up, we run a new analysis where the starting points are 3 Twitter accounts of epidemiologists that were found in these clusters. The end goal is to identify many more epidemiologists.

Part 2: covid-19 on Twitter, with a focus on 3 new seed accounts

  1. 1. Re-focusing on 3 Twitter accounts Follow up to the first part published on Slideshare: https://www.slideshare.net/seinecle/covid-actors-relations-and-topics-on-twitter-as-of-march-30-2020 published on April 1, 2020 by Clément Levallois, Associate Professor at emlyon business school Based on the methodology published in (free pdf download): Benabdelkrim, M., Levallois, C., Savinien, J., & Robardet, C. (2020). Opening Fields: A Methodological Contribution to the Identification of Heterogeneous Actors in Unbounded Relational Orders.

  2. 2. In the previous study, we found 3 clusters of interest for epidemiology specialists: See https://www.slideshare.net/seinecle/covid-actors-relations-and-topics-on-twitter-as-of-march-30-2020/12 -> We now pick the Twitter accounts that are most central to each cluster: @SCBriand, @JenniferNuzzo and @SCBriand
  3. 3. Using these 3 accounts as seeds, we run the method to find related accounts Because our interest here is to zoom in on epidemiologists. We could have chosen any other focus (journalists, healthcare companies, state organizations, etc.)
