Interpreting Emoji with Emoji

Abstract

We study the extent to which emoji can be used to add interpretability to embeddings of text and emoji.To do so, we extend the POLAR-framework that transforms word embeddings to interpretable counterparts and apply it to word-emoji embeddings trained on four years of messaging data from the Jodel social network.We devise a crowdsourced human judgement experiment to study six usecases, evaluating against words only, what role emoji can play in adding interpretability to word embeddings.That is, we use a revised POLAR approach interpreting words and emoji with words, emoji or both according to human judgement.We find statistically significant trends demonstrating that emoji can be used to interpret other emoji very well.
