*** OVERVIEW ***

Given the paramount importance of visual icons for providing an 
additional layer of meaning to social media messages, on one hand, and 
the indisputable role of Twitter as one of the most important social 
media platforms, on the other, we propose the Emoji Prediction task. We 
invite participants to submit systems designed to predict, given a tweet 
in English or Spanish, its most likely associated emoji. We will 
challenge systems to predict emojis among a wide and heterogeneous emoji 
space. As for the experimental setting, we remove the emoji from the 
tweet and ask users to predict it, ignoring tweets including more than 
one emoji, for simplicity purposes (same settings as in [1]). We will 
provide data for two tasks:

Subtask 1: Emoji Prediction in English
Subtask 2: Emoji Prediction in Spanish

Participants can take part in one or two of the subtasks.
