A paper on emoji and collective identity on Twitter.

We propose a measure for group identity on Twitter using emoji displayed by users in their names or biographies. Viewing the use of emoji as social phenomenon, we introduce methods for measuring how often emoji users follow/friend other emoji users compared to non-emoji users. Furthermore, we introduce methods to measure quantify the frequency users friend/follow users with similar emojis, concluding with visual analysis of what ties between certain emoji look like.
