SwissAlps at SemEval-2017 Task 3: Attention-based Convolutional Neural Network for Community Question Answering

Abstract

In this paper we propose a system for re-ranking answers for a given question. Our method builds on a siamese CNN architecture which is extended by two attention mechanisms. The approach was evaluated on the datasets of the SemEval-2017 competition for Community Question Answering (cQA), where it achieved 7th place obtaining a MAP score of 86.24 points on the Question-Comment Similarity subtask.
