摘要:

在从电子商务网站购买产品时,客户通常会有很多问题。从电子商务服务提供商和客户的角度来看,必须有一个有效的问答系统,以提供即时的答案,用户的查询。虽然某些问题只能在使用产品后才能回答,但有许多问题可以从产品说明书本身回答。我们的工作在这个方向上迈出了第一步,找到了相关的产品规格,这可以帮助回答用户的问题。我们提出了一种方法来自动创建这个问题的训练数据集。我们利用最近提出的XLNet和BERT架构,这个问题,发现他们提供了更好的性能比暹罗模型,以前应用于这个问题。我们的模型即使在一个垂直领域进行训练并在不同的垂直领域进行测试,也能提供良好的性能。

英文摘要:

While buying a product from the e-commerce websites, customers generally have a plethora of questions. From the perspective of both the e-commerce service provider as well as the customers, there must be an effective question answering system to provide immediate answers to the user queries. While certain questions can only be answered after using the product, there are many questions which can be answered from the product specification itself. Our work takes a first step in this direction by finding out the relevant product specifications, that can help answering the user questions. We propose an approach to automatically create a training dataset for this problem. We utilize recently proposed XLNet and BERT architectures for this problem and find that they provide much better performance than the Siamese model, previously applied for this problem. Our model gives a good performance even when trained on one vertical and tested across different verticals.
