1. Mapping the actors, their relations and sub-groups Covid-19 on Twitter published on March 31, 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. M@n@gement, 23(1), 4-18. https://doi.org/10.37725/mgmt.v23.4245 Contact: levallois@em-lyon.com or @seinecle on Twitter

2. Very brief note on these pictures 1. I selected 3 Twitter accounts: @COVID19Tracking @CoronavirusESP and @ItaliaCovid19 2. Then our algorithm identified thousands of similar Twitter accounts, based on the Twitter lists they share 3. The pictures show similar Twitter accounts next to each other. Groups of closely similar Twitter accounts are shown in different colors. 4. Text analysis: for each group of Twitter accounts, an algorithm identifies the most relevant words (most frequent words in the Twitter bios of the members of the group) See this free

3. Objectives and disclaimer - These maps are provided ‘as is’, in the hope they will be useful to the individuals and organizations trying to make sense of the epidemics (journalists? NGOs? Governments?) - Get in touch at levallois@em-lyon.com for questions and further research
