AI总结:

本文针对下一购物篮推荐(NBR)算法缺乏统一评估的问题,在相同数据集和实验设置下系统性地比较了多种代表性NBR算法的性能,为未来研究提供了统一的公平评估框架与参考。

摘要:

下一购物篮推荐系统(NBRs)旨在通过基于用户的购买历史(通常是一系列历史购物篮)建模用户对物品的偏好,来推荐用户的下一个(购物)购物篮中的物品。由于其在现实世界电子商务行业中的广泛适用性,近年来NBR的研究受到了越来越多的关注。NBRs已被广泛研究,并取得了很大进展,提出了多种NBR方法。然而,一个重要问题是缺乏对各种NBR方法的系统和统一评估。不同的研究通常在不同的数据集上、不同的实验设置下评估NBR方法,这使得难以公平有效地比较不同NBR方法的性能。为了弥补这一空白,我们在NBR领域进行了一项系统的实证研究。具体而言,我们回顾了NBR中的代表性工作,并分析了它们的优缺点。然后,我们在相同的数据集上、相同的实验设置下运行选定的NBR算法,并使用相同的指标评估它们的性能。这提供了一个公平比较不同NBR方法的统一框架。我们希望这项研究能为这一活跃领域的未来研究提供有价值的参考。

英文摘要:

Next basket recommender systems (NBRs) aim to recommend a user's next (shopping) basket of items via modeling the user's preferences towards items based on the user's purchase history, usually a sequence of historical baskets. Due to its wide applicability in the real-world E-commerce industry, the studies NBR have attracted increasing attention in recent years. NBRs have been widely studied and much progress has been achieved in this area with a variety of NBR approaches having been proposed. However, an important issue is that there is a lack of a systematic and unified evaluation over the various NBR approaches. Different studies often evaluate NBR approaches on different datasets, under different experimental settings, making it hard to fairly and effectively compare the performance of different NBR approaches. To bridge this gap, in this work, we conduct a systematical empirical study in NBR area. Specifically, we review the representative work in NBR and analyze their cons and pros. Then, we run the selected NBR algorithms on the same datasets, under the same experimental setting and evaluate their performances using the same measurements. This provides a unified framework to fairly compare different NBR approaches. We hope this study can provide a valuable reference for the future research in this vibrant area.
