神经IR满足图嵌入:一个产品搜索的排序模型

Neural IR Meets Graph Embedding: A Ranking Model for Product Search

Yuan Zhang, Dong Wang, Yan Zhang

摘要:

近年来,神经网络模型在信息检索中的应用越来越广泛。由于它们在语义匹配方面的竞争优势,为产品搜索提供了有效的途径。然而,它是具有挑战性的,使用基于图的功能,虽然证明非常有用的IR文献中,在这些神经方法。在本文中,我们利用图嵌入技术的最新进展,使神经检索模型,利用图结构的数据自动特征提取。该方法不仅有助于克服点击数据的长尾问题,而且还可以结合外部异构信息来改善搜索结果。在真实世界的电子商务数据集上进行的大量实验表明,我们提出的方法在多个强基线上取得了显着的改进,无论是作为一个单独的检索模型,还是作为学习排名框架中使用的一个功能。

英文摘要:

Recently, neural models for information retrieval are becoming increasingly popular. They provide effective approaches for product search due to their competitive advantages in semantic matching. However, it is challenging to use graph-based features, though proved very useful in IR literature, in these neural approaches. In this paper, we leverage the recent advances in graph embedding techniques to enable neural retrieval models to exploit graph-structured data for automatic feature extraction. The proposed approach can not only help to overcome the long-tail problem of click-through data, but also incorporate external heterogeneous information to improve search results. Extensive experiments on a real-world e-commerce dataset demonstrate significant improvement achieved by our proposed approach over multiple strong baselines both as an individual retrieval model and as a feature used in learning-to-rank frameworks.
