The Koo interaction network and the impact of linguistic homophily on the network’s structure.

Each node represents a user, and two nodes are connected if one of the users interacted with the other user’s content. Users are colored according to their modal language on the platform. The main linguistic communities are the Hindi-speaking users (blue), English-speaking users (green), Nigerian users (purple) and Portuguese-speaking users (yellow). The layout is generated by using a force-directed graph drawing algorithm. A) The total interaction network. B) The k-core of the interaction network with k = 150. C) The Shannon entropy of the modal language of the nodes belonging to the k-core of the graph, with respect to the value of k. The entropy of the interaction network is compared to the value obtained in a null model, where we shuffle the modal language associated to each node in the network. For an alternative network visualization with greater clarity of the different language groups active on Koo, we refer the reader to Fig 2 in our original Koo dataset paper [15] where we present a network of “accounts of eminence” on Koo (similar to verified users) labeled according to language.
