DSIRM: Learning Query-Bridged Discrete Semantic Identifiers for E-commerce Relevance Modeling
Researchers have developed DSIRM, a machine learning model that improves e-commerce search relevance by combining discrete semantic identifiers with query-dependent ranking. The system achieved a 1.54% offline AUC improvement and significant online gains (+0.13% UCTR, +0.25% UCTCVR) when deployed on Tmall's platform, demonstrating practical value for large-scale recommendation systems.
