Fig 5. K-core decomposition of the July 2019 semantic networks for the M5S (top left) and the MINGOs (bottom left) partisan communities.

The k-core decomposition reveals the bulk of the discussion about immigration developed by these two partisan communities: while the M5S community displays a mixed behavior towards immigration policies, as shown by the hashtags #freecarola and #bibbiano, the MINGOs innermost k-shell uncovers a strong support towards pro-migration positions, as proven by the hashtags #ioaccolgo (‘I host’), #iostoconcarola (‘I stand with Carola’) and #facciamorete (‘let us act as a network’).
