In: 15th Conference of the European Chapter of the Association for Computational Linguistics:, Valencia, Spain.
Abstract
We show that a neural approach to the task of non-factoid answer reranking can benefit from the inclusion of tried-and-tested
handcrafted features. We present a novel neural network architecture based on a combination of recurrent neural networks
that are used to encode questions and answers, and a multilayer perceptron. We show how this approach can be combined
with additional features, in particular, the discourse features presented by Jansen et al. (2014). Our neural approach achieves state-of-the-art performance on a public dataset from Yahoo! Answers and its performance is further improved by incorporating the discourse features. Additionally, we present a new dataset of Ask Ubuntu questions where the hybrid approach also achieves good results.
