摘要:

随着跨境电子商业的蓬勃发展,迫切需要设计智能化的方法来帮助电子商业卖家为来自世界各地的消费者提供当地产品。本文探讨了跨语言信息检索的一个新任务,即,跨境电子商业中的跨语言集合到描述检索,其涉及将源语言中的产品属性集合与目标语言中的有说服力的产品描述进行匹配。我们手动收集一个新的和高质量的配对数据集,其中每对包含一个无序的产品属性集的源语言和信息丰富的产品描述的目标语言。由于数据集构建过程既耗时又昂贵,新数据集仅包含13.5k对,这是一个低资源设置,可以被视为跨境电子商业模型开发和评估的具有挑战性的测试平台。为了解决这种跨语言集到描述检索任务,我们提出了一种新的跨语言匹配网络(CLMN)与增强的上下文相关的跨语言映射的预训练单语BERT表示。实验结果表明,我们提出的CLMN在具有挑战性的任务上产生了令人印象深刻的结果,并且与预训练的多语言BERT模型相比,BERT上的上下文相关的跨语言映射产生了显着的改进。

英文摘要:

With the prosperous of cross-border e-commerce, there is an urgent demand for designing intelligent approaches for assisting e-commerce sellers to offer local products for consumers from all over the world. In this paper, we explore a new task of cross-lingual information retrieval, i.e., cross-lingual set-to-description retrieval in cross-border e-commerce, which involves matching product attribute sets in the source language with persuasive product descriptions in the target language. We manually collect a new and high-quality paired dataset, where each pair contains an unordered product attribute set in the source language and an informative product description in the target language. As the dataset construction process is both time-consuming and costly, the new dataset only comprises of 13.5k pairs, which is a low-resource setting and can be viewed as a challenging testbed for model development and evaluation in cross-border e-commerce. To tackle this cross-lingual set-to-description retrieval task, we propose a novel cross-lingual matching network (CLMN) with the enhancement of context-dependent cross-lingual mapping upon the pre-trained monolingual BERT representations. Experimental results indicate that our proposed CLMN yields impressive results on the challenging task and the context-dependent cross-lingual mapping on BERT yields noticeable improvement over the pre-trained multi-lingual BERT model.
