The above contributions, in addition to emoji similarity datasets (Barbieri et al., 2016;Wijeratne et al., 2017) or emoji sentiment lexicons (Novak et al., 2015;Wijeratne et al., 2016;Kimura and Katsurai, 2017;Rodrigues et al., 2018), have paved the way for better understanding the semantics of emojis.
our understanding of what exactly the neural models for emoji prediction are capturing is currently very limited.
