摘要:

蓬勃发展的在线电子商业平台需要高度准确的方法来细分查询,携带消费者的产品需求。最近的工作表明,监督方法,特别是那些基于深度学习,是有吸引力的,以实现更好的性能的问题上的查询分割。然而,缺乏标记数据仍然是训练深度分割网络的一大挑战,并且词汇表外(OOV)问题也对查询分割的性能产生不利影响。与开放域中的查询分割任务不同,电子商业场景可以提供与这些查询密切相关的外部文档。因此,为了应对这两个挑战,我们采用了远程监督的思想,并设计了一种新的方法来发现外部文档中的上下文,并从这些上下文中提取特征。在这项工作中,我们提出了一个基于BiLSTM-CRF的模型与注意力模块编码的外部功能,使外部上下文信息,可以自然和有效地利用,以帮助查询分割。在两个数据集上的实验表明,与几种基线相比,我们的方法是有效的。

英文摘要:

The booming online e-commerce platforms demand highly accurate approaches to segment queries that carry the product requirements of consumers. Recent works have shown that the supervised methods, especially those based on deep learning, are attractive for achieving better performance on the problem of query segmentation. However, the lack of labeled data is still a big challenge for training a deep segmentation network, and the problem of Out-of-Vocabulary (OOV) also adversely impacts the performance of query segmentation. Different from query segmentation task in an open domain, e-commerce scenario can provide external documents that are closely related to these queries. Thus, to deal with the two challenges, we employ the idea of distant supervision and design a novel method to find contexts in external documents and extract features from these contexts. In this work, we propose a BiLSTM-CRF based model with an attention module to encode external features, such that external contexts information, which can be utilized naturally and effectively to help query segmentation. Experiments on two datasets show the effectiveness of our approach compared with several kinds of baselines.
