About this paper

Hui Zhou, Jian Hui Ji, Lei Ma, Rong Xiao, Xiaoyi Zeng

SAM-D2Q adds relevant, image-supported query terms to e-commerce product records before Boolean indexing, filtering out title-covered terms and training visual attributes through counterfactual masking. It also scores new terms for relevance and commercial value. At Top-3000, it raises relevant retrieved items 30.7% over original-title retrieval. In a live test, the full module lifted GMV 3.38% and Pay Count 2.27% on active products.
