Community-Based Question Answering via Asymmetric Multi-Faceted Ranking Network Learning

Nowadays the community-based question answering (CQA) site has become the popular Internet-based web service, which has accumulated millions of questions and their posted answers over time. Thus, the question answering becomes an essential problem in CQA site, which ranks the high-quality answers to the given questions. Currently, most of the existing works consider the problem of question answering as text matching task that ranks the answers based on their semantic relevance, while ignoring the authority of answerers to the given question. In this paper, we consider the problem of community-based question answering from the viewpoint of asymmetric multi-faceted ranking network learning. We propose a novel asymmetric multi-faceted ranking network learning framework for question answering by exploiting both answers’ relative quality rank to given questions and the answerers’ following relations in CQA sites. We then develop an asymmetric multi-faceted ranking network learning method with recurrent neural networks for communitybased question answering. The extensive experiments on a large-scale dataset from a real world CQA site show that our method achieves better performance than other state-of-theart solutions to the problem.
