Presentation transcript:

Hashtag ecosystem reveals group identity. Hashtag ecosystem reveals group identity. Hashtags are coupled together if they appear simultaneously in a message, building a network of concepts. Analyzing the hashtag networks obtained from each group, we identify the hashtags which are ranked similarly (A) and very differently (B) in the two groups to visualize the corresponding neighboring concepts. In A, low-ranked hashtags coexist in both groups and do not allow us to identify the underlying ideology of each group. In B, top-ranked hashtag that exist only in group 1 are strongly related to concepts of freedom, independence, fight, shame against the Spanish government, dictatorship, and blame against police violence, providing evidence that group 1 consists of Catalan Independentists. Remarkably, concepts related to “sonunesbesties” (translated as “they are beasts”)—highlighted in B—are posted by bots only, whereas the other hashtag networks have contributions by both humans and bots. Note that, for clarity, in B we show only hashtags fully characterizing accounts associated with Independentists. Massimo Stella et al.
