Applying Deep Learning to Answer Selection: A Study and An Open Task

7 Aug 2015  ·  Minwei Feng, Bing Xiang, Michael R. Glass, Lidan Wang, Bo-Wen Zhou ·

We apply a general deep learning framework to address the non-factoid question answering task. Our approach does not rely on any linguistic tools and can be applied to different languages or domains. Various architectures are presented and compared. We create and release a QA corpus and setup a new QA task in the insurance domain. Experimental results demonstrate superior performance compared to the baseline methods and various technologies give further improvements. For this highly challenging task, the top-1 accuracy can reach up to 65.3% on a test set, which indicates a great potential for practical use.
