| contents | Personalized product search (PPS) aims to retrieve products relevant to the given query considering user preferences within their purchase histories. Since large language models (LLM) exhibit impressive potential in content understanding and reasoning, current methods explore to leverage LLM to comprehend the complicated relationships among user, query and product to improve the search performance of PPS. Despite the progress, LLM-based PPS solutions merely take textual contents into consideration, neglecting multimodal contents which play a critical role for product search. Motivated by this, we propose a novel framework, HMPPS, for \textbf{H}arnessing \textbf{M}ultimodal large language models (MLLM) to deal with \textbf{P}ersonalized \textbf{P}roduct \textbf{S}earch based on multimodal contents. Nevertheless, the redundancy and noise in PPS input stand for a great challenge to apply MLLM for PPS, which not only misleads MLLM to generate inaccurate search results but also increases the computation expense of MLLM. To deal with this problem, we additionally design two query-aware refinement modules for HMPPS: 1) a perspective-guided summarization module that generates refined product descriptions around core perspectives relevant to search query, reducing noise and redundancy within textual contents; and 2) a two-stage training paradigm that introduces search query for user history filtering based on multimodal representations, capturing precise user preferences and decreasing the inference cost. Extensive experiments are conducted on four public datasets to demonstrate the effectiveness of HMPPS. Furthermore, HMPPS is deployed on an online search system with billion-level daily active users and achieves an evident gain in A/B testing. |
