DataStories at SemEval-2017 Task 6: Siamese LSTM with Attention for Humorous Text Comparison

Abstract

In this paper we present a deep-learning system that competed at SemEval-2017 Task 6 ''\#HashtagWars: Learning a Sense of Humor''. We participated in Subtask A, in which the goal was, given two Twitter messages, to identify which one is funnier. We propose a Siamese architecture with bidirectional Long Short-Term Memory (LSTM) networks, augmented with an attention mechanism. Our system works on the token-level, leveraging word embeddings trained on a big collection of unlabeled Twitter messages. We ranked 2nd in 7 teams. A post-completion improvement of our model, achieves state-of-the-art results on \#HashtagWars dataset.
