EPUTION at SemEval-2018 Task 2: Emoji Prediction with User Adaption

Abstract

This paper describes our approach, called EPUTION, for the open trial of the SemEval-2018 Task 2, Multilingual Emoji Prediction. The task relates to using social media - more precisely, Twitter - with its aim to predict the most likely associated emoji of a tweet. Our solution for this text classification problem explores the idea of transfer learning for adapting the classifier based on users' tweeting history. Our experiments show that our user-adaption method improves classification results by more than 6 per cent on the macro-averaged F1. Thus, our paper provides evidence for the rationality of enriching the original corpus longitudinally with user behaviors and transferring the lessons learned from corresponding users to specific instances.
