论文摘要
在个性化产品搜索中,用户偏好建模是一个至关重要但充满挑战的问题。近年来,基于潜在空间的方法通过共同学习产品,用户和文本令牌的语义表示来实现最先进的性能。但是,现有方法的建模能力受到限制。他们通常使用细心的模型在短时间内访问的产品代表用户,并且缺乏利用关系信息(例如用户产品交互或项目共发生关系)的能力。在这项工作中,我们建议通过在用户连续行为图上探索本地和全局用户行为模式来解决先前艺术的局限性,该模式是通过利用所有用户的短期操作来构建的。为了捕获隐式用户偏好信号和协作模式,我们使用有效的跳跃图卷积来探索高阶关系,以丰富用户偏好模型的产品表示。我们的方法可以与现有的潜在空间方法无缝集成,并有可能在使用购买历史记录来模拟用户偏好的任何产品检索方法中应用。对八个亚马逊基准测试的广泛实验证明了我们方法的有效性和潜力。源代码可在\ url {https://github.com/floatsdsds/sbg}中获得。
User preference modeling is a vital yet challenging problem in personalized product search. In recent years, latent space based methods have achieved state-of-the-art performance by jointly learning semantic representations of products, users, and text tokens. However, existing methods are limited in their ability to model user preferences. They typically represent users by the products they visited in a short span of time using attentive models and lack the ability to exploit relational information such as user-product interactions or item co-occurrence relations. In this work, we propose to address the limitations of prior arts by exploring local and global user behavior patterns on a user successive behavior graph, which is constructed by utilizing short-term actions of all users. To capture implicit user preference signals and collaborative patterns, we use an efficient jumping graph convolution to explore high-order relations to enrich product representations for user preference modeling. Our approach can be seamlessly integrated with existing latent space based methods and be potentially applied in any product retrieval method that uses purchase history to model user preferences. Extensive experiments on eight Amazon benchmarks demonstrate the effectiveness and potential of our approach. The source code is available at \url{https://github.com/floatSDSDS/SBG}.
