MPIUR：融合商品信息与用户评论的多模态图推荐模型
A Technique to Model Product Information and User Reviews (MPIUR)
AI 导读
MPIUR 是一个多模态图推荐模型，将用户评论编码进异构图，并对齐图像与文本表示，同时按商品交互密度自适应调整协同—语义对齐。在 Amazon Reviews 2023 的 Musical Instruments 和 Baby 两个类目上，MPIUR 在评测方法中取得最佳全局 nDCG@10 与 Recall@10，在稀疏商品上也同样领先，说明联合利用评论与多模态商品内容在交互历史有限时尤为有效。

Abstract:Modern e-commerce platforms naturally provide three complementary modalities: textual item descriptions, item images, and user reviews. However, existing multimodal recommendation methods often omit reviews or do not integrate all three modalities within a unified framework. In this paper, we propose MPIUR, a multimodal graph-based recommendation model that encodes reviews in heterogeneous graphs, aligns image and text representations, and adapts collaborative--semantic alignment to item interaction density. Experiments on the Amazon Reviews 2023 Musical Instruments and Baby categories show that MPIUR achieves the best global nDCG@10 and Recall@10 among the evaluated methods on both datasets. It also obtains the best nDCG@10 and Recall@10 on sparse items, indicating that jointly exploiting reviews and multimodal item content is particularly useful when interaction histories are limited.
